Best Newsletter Platforms for SaaS in 2025

Newsletter Features: Substack pioneered the newsletter-as-publication model and their editor reflects this philosophy. Writing on Substack feels like publishing, not email marketing. The editor is clean and focused, supporting rich text formatting, images, embedded tweets and videos, footnotes, and audio/podcast integration. Every newsletter automatically becomes a web post with SEO optimization, comments, and social sharing. Substack introduced "Notes" - a Twitter-like feature for sharing shorter thoughts and engaging with other Substack writers. The publication settings let you customize branding (within limits), set up sections for different content types, and manage publication schedules. While less flexible than Ghost or self-hosted options, Substack's constraints often help writers focus on what matters: the writing itself.

Subscriber Management: Substack's subscriber management is intentionally simple. Subscribers are either free, paid monthly, or paid annually - that's the primary segmentation. You can view subscriber lists, see when they joined, and check their engagement metrics (open rates, click patterns). The platform handles all payment processing through Stripe and manages subscription lifecycles automatically - billing, failed payment recovery, and cancellation. What Substack lacks in advanced segmentation (no tagging, no custom fields, no behavioral triggers) it makes up for in simplicity. For writers focused on content rather than marketing operations, this simplicity is a feature. Export your subscriber list anytime with full email addresses - Substack doesn't hold your audience hostage. The analytics dashboard shows growth trends, engagement patterns, and revenue metrics in an easily digestible format.

Monetization: Substack is built around paid newsletter subscriptions. Enable paid subscriptions with one click, set your price, and start earning. Substack takes 10% of revenue (plus Stripe's ~3%), making it more expensive than alternatives at scale but with zero upfront cost. The platform provides paywalling for individual posts or entire publications, founding member pricing for early supporters, and group subscription discounts for organizations. What makes Substack's monetization powerful is the network effect - the platform promotes newsletters to readers, and successful writers attract attention that lifts other publications. Many writers report that Substack's discovery features drive meaningful subscriber growth. The downside is the 10% take rate forever - at $10,000/month in revenue, you're paying $1,000/month to Substack. For comparison, Ghost charges $25/month flat with 0% transaction fees.

Growth Tools: Substack's growth strategy centers on network effects. The recommendation feature lets writers suggest other newsletters to their subscribers, creating a web of cross-promotion. When readers finish a post, they're shown recommendations from both the writer and Substack's algorithm. Substack Notes extends this by letting writers share shorter content that can drive newsletter signups. The Leaderboards surface popular publications by category. For writers, the strategy is clear: participate in the Substack ecosystem, recommend others, and benefit from reciprocal recommendations. The platform's apps (iOS and Android) give readers a unified newsletter inbox, increasing engagement across all publications. What Substack lacks is traditional growth tools like landing page builders, embedded forms for external websites, or referral programs with incentives. Growth comes through content and network, not marketing mechanics.

Newsletter Features: Beehiiv's editor is one of the best in the newsletter space. Built with a Notion-like block structure, it supports drag-and-drop layout customization, reusable content blocks, and rich media embedding. You can create templates for consistent formatting across issues, use the AI writing assistant for brainstorming and editing, and preview exactly how emails will render in different clients. The scheduling system includes timezone optimization to send at the best time for each subscriber. Beehiiv also supports multi-author publications with contributor management and editorial workflows. Every newsletter automatically publishes to a customizable web archive with SEO optimization, RSS feeds, and social meta tags. The platform recently added "Threads" for shorter, Twitter-style updates that keep subscribers engaged between newsletter issues.

Subscriber Management: Beehiiv provides sophisticated subscriber management built for publishers at scale. Subscribers can be segmented by engagement level (highly engaged, engaged, inactive), acquisition source, signup date, and custom tags. The platform automatically identifies subscribers who haven't opened recent emails, making it easy to run re-engagement campaigns or clean your list. Subscriber profiles show complete engagement history, referral activity, and survey responses. The preference center lets subscribers choose which content types they want to receive and how often. Beehiiv's automation features enable triggered sequences based on subscriber behavior - welcome series, engagement-based content, and win-back campaigns. Import/export supports major platforms with attribute mapping, and the API enables custom integrations with your other tools.

Monetization: Beehiiv offers multiple monetization paths. Premium subscriptions let you paywall content with flexible pricing (monthly, annual, or both). The platform takes 0% of subscription revenue on paid plans (only Stripe's standard fees apply). Beyond subscriptions, Beehiiv operates an ad network that connects newsletters with advertisers, providing revenue without requiring you to sell sponsorships yourself. The Boost program pays you when your recommended newsletters gain paid subscribers. For newsletters with significant traffic, these combined revenue streams can outperform subscription-only models. Beehiiv also supports digital product sales and integrates with payment processors for merchandise or course sales. The analytics dashboard shows revenue by source, subscriber lifetime value, and monetization trends.

Growth Tools: Growth is Beehiiv's defining strength. The referral program (called "Refer-a-Friend") lets subscribers earn rewards for bringing in new signups - configure milestones, rewards, and tracking automatically. The recommendation network cross-promotes newsletters to aligned audiences, and the Boost program incentivizes recommendations with revenue sharing. Landing pages are fully customizable with the drag-and-drop builder, supporting A/B testing and analytics. Embedded signup forms work on any website, and the API supports custom signup flows. Beehiiv's analytics go deep on acquisition: track which sources, landing pages, and content pieces drive the most valuable subscribers. The platform also supports magic link subscriptions (one-click signup from other newsletters), Twitter Verification for frictionless mobile signup, and pop-up forms with targeting rules. For newsletters pursuing aggressive growth, Beehiiv's toolkit is unmatched.

Newsletter Features: ConvertKit's newsletter editor prioritizes readability and deliverability over flashy design. The clean, minimal templates are intentionally simple - research shows plain-text styled emails often outperform heavily designed ones. The editor supports basic formatting, images, buttons, and custom HTML for those who want more control. ConvertKit's strength is in broadcast scheduling and consistent delivery. Schedule newsletters in advance, set timezone-adjusted sending, and trust that emails will land in inboxes. The platform also supports "Sequences" - automated email series that can serve as evergreen newsletters or onboarding content. What ConvertKit lacks in design flexibility, it compensates for with reliability and focus on what matters: getting your content read.

Subscriber Management: ConvertKit uses a tag-based subscriber system rather than traditional lists. This means one subscriber can have multiple tags but only exists once in your database - no more duplicate management headaches. Tags are added automatically through form submissions, link clicks, purchases, or manual rules. Segments combine tags with conditional logic for targeted broadcasting. The subscriber profile shows complete tag history, email activity, and custom field data. ConvertKit's automation builder (Visual Automations) creates sophisticated subscriber journeys based on behavior - tag changes trigger sequences, link clicks add tags, purchases trigger fulfillment emails. The "cold subscriber" feature identifies inactive subscribers for re-engagement or removal. List hygiene happens automatically with bounce handling and complaint management.

Monetization: ConvertKit supports creator monetization through several channels. Paid newsletter subscriptions let you charge monthly or annually for premium content, with flexible paywalling options. The platform charges a 3.5% + $0.30 transaction fee on top of Stripe processing. ConvertKit Commerce enables selling digital products directly - ebooks, courses, templates, or any downloadable content. These can be one-time purchases or subscription products. Tip jars let audience members support free content with voluntary payments. For SaaS companies, ConvertKit's monetization features are less relevant since you're likely monetizing through your software product. However, if you're creating educational content that could be productized (courses, templates, guides), ConvertKit's commerce features are mature and well-integrated.

Growth Tools: ConvertKit's growth tools focus on conversion optimization rather than viral mechanics. Landing pages are fully customizable with their drag-and-drop builder and convert well for newsletter signups. Signup forms come in multiple formats: inline, modal, slide-in, and sticky bar. The Creator Network allows cross-promotion between ConvertKit creators, similar to Substack's recommendations. Link pages (like Linktree alternatives) consolidate your web presence with newsletter signup. What ConvertKit lacks is a referral program - there's no built-in way to incentivize subscribers to share. However, you can build simple referral tracking using tags and automation. ConvertKit's real growth advantage is deliverability - their reputation management and email authentication setup help ensure your content reaches inboxes, which compounds over time as engagement rates stay high.

Newsletter Features: Buttondown is what newsletters would be if a developer designed them. The editor is markdown-first, meaning you write in plain text with simple formatting syntax and Buttondown converts it to beautiful emails. For developers and technical writers, this is a superpower - no fighting with WYSIWYG editors, no unexpected formatting, just clean text that renders predictably. The editor supports syntax-highlighted code blocks, making it perfect for dev changelogs and technical newsletters. You can also paste HTML directly for custom sections. Buttondown supports RSS-to-email (automatically send newsletters when you publish blog posts), scheduling, and basic A/B testing. The interface is intentionally spartan - there's almost nothing to learn, so you can focus entirely on writing.

Subscriber Management: Subscriber management in Buttondown is straightforward and no-nonsense. Import subscribers from any platform via CSV. View and export your list anytime. Tag subscribers manually or through automation. Create segments based on tags or engagement metrics. That's it. There's no complex automation builder, no elaborate customer journey mapping, no AI-powered predictions. For many newsletter writers, this simplicity is exactly right - you probably don't need enterprise marketing features for a 5,000 subscriber newsletter. Buttondown automatically handles bounces and unsubscribes, maintains list hygiene, and provides basic engagement stats (opens, clicks). The subscriber API lets developers build custom integrations when needed.

Monetization: Buttondown supports paid newsletters with Stripe integration. Set up monthly or annual pricing, paywall specific content, and manage subscriber billing directly from the dashboard. The platform takes no cut of your revenue beyond Stripe's standard fees - just pay your monthly Buttondown subscription. For developers running technical newsletters, this economics works out favorably compared to percentage-based platforms like Substack. Buttondown also supports sponsorship management with dedicated sponsorship blocks and tracking. You can define sponsor slots, track impressions and clicks, and generate reports for sponsors. While less automated than Beehiiv's ad network, it gives you full control over your sponsorship relationships.

Growth Tools: Buttondown intentionally offers minimal growth tools. There's no referral program, no recommendation network, no viral mechanics. What you get: embeddable signup forms, a customizable landing page, and a solid API for building custom signup flows. This philosophy matches Buttondown's user base - developers and technical writers who grow through content quality, SEO, and word-of-mouth rather than growth hacking. If your newsletter succeeds on the merit of its content, Buttondown provides everything you need. If you need sophisticated acquisition funnels and viral loops, look elsewhere. For SaaS developer newsletters specifically (changelogs, dev updates, technical content), Buttondown's simplicity is often an asset rather than a limitation.

Newsletter Features: Ghost is a full publishing platform where newsletters are one piece of a larger content strategy. The editor is phenomenal - a clean, distraction-free writing environment with rich media support, embeds, and flexible layout options. Every post can be simultaneously published to your website and sent as a newsletter. You have complete control over newsletter design with custom email templates and branding. Ghost supports multiple newsletter types (different audiences can receive different content), scheduling, and detailed send analytics. The platform also includes podcast hosting, memberships, and premium content gating. For SaaS companies wanting a unified blog + newsletter + membership platform, Ghost offers the most comprehensive solution without the bloat of WordPress or the limitations of Substack.

Subscriber Management: Ghost calls subscribers "members" and treats them as the center of your publishing business. Members can be free (receive newsletters and access free content) or paid (access premium content and features). The member directory shows engagement metrics, subscription status, and complete activity history. Segment members by status, labels, newsletter preferences, or engagement level. Ghost's email import supports major platforms and preserves member history. The platform handles transactional emails (signup confirmations, billing receipts) automatically. One unique feature is member management through the Ghost Admin API - developers can build sophisticated integrations with their products, syncing member status, adding custom attributes, or triggering platform-specific actions.

Monetization: Ghost offers perhaps the best newsletter monetization economics in the market. Enable paid memberships with flexible pricing - monthly, annual, or both. Offer founding member pricing for early supporters. Create multiple membership tiers with different benefits. And here's the key: Ghost takes 0% of your revenue. You pay your monthly Ghost subscription ($9-25/month for hosted, or free if self-hosted) and keep 100% of member revenue (minus Stripe fees). At scale, this saves thousands compared to Substack's 10% or ConvertKit's 3.5%. Ghost also supports one-time donations through the "Tips" feature and integrates with services like Memberful for additional membership flexibility. For newsletters aiming to build sustainable, profitable publishing businesses, Ghost's economics are unbeatable.

Growth Tools: Ghost's growth approach combines organic discovery with technical flexibility. All content is published to SEO-optimized web pages with proper meta tags, structured data, and fast loading times. The built-in theme system supports fully custom designs that reflect your brand. Signup forms embed anywhere, and Ghost's Zapier integration connects to other growth tools. The platform supports custom integrations through its API - connect Ghost to your CRM, product database, or analytics tools. What Ghost lacks is built-in viral mechanics (no referral programs, no recommendation network). Growth comes through content quality, SEO, and the reputation you build. For publishers willing to invest in long-term content strategy rather than growth hacking, Ghost provides the foundation for sustainable audience building.

Newsletter Features: Mailerlite offers a capable newsletter editor that punches above its price point. The drag-and-drop builder includes a variety of content blocks (text, images, buttons, social links, video, countdown timers) and pre-designed templates to start from. A rich text editor option provides simpler formatting for those who prefer writing over designing. Newsletters automatically generate web versions with sharing options. The scheduling system supports timezone sending and can optimize delivery time based on subscriber engagement patterns. Mailerlite recently added AI features for subject line generation and content suggestions. While not as polished as Beehiiv or Ghost, the editor handles standard newsletter needs competently and without friction.

Subscriber Management: Mailerlite uses a group-based subscriber organization system. Subscribers can belong to multiple groups, and you can segment based on group membership, engagement, location, or custom fields. The subscriber dashboard shows import history, engagement trends, and list growth over time. Automation triggers based on subscriber actions (signup, link click, purchase) enable welcome sequences and behavioral campaigns. The platform automatically handles bounces, complaints, and unsubscribes to maintain list hygiene. What Mailerlite does well is making subscriber management accessible without overwhelming complexity - small teams and solo creators can manage their lists without email marketing expertise.

Monetization: Mailerlite's monetization features are basic compared to specialized newsletter platforms. You can sell digital products and subscriptions through their e-commerce integration, accepting payments via Stripe or PayPal. The platform supports paid newsletter subscriptions with gated content blocks. Landing pages can include payment forms for product sales. However, Mailerlite wasn't designed primarily for newsletter monetization - features feel bolted on rather than native. For newsletters focused on paid subscriptions as the primary business model, platforms like Ghost, Substack, or Beehiiv offer more sophisticated tools. Mailerlite works best when the newsletter supports other revenue (SaaS product, services, advertising) rather than being the product itself.

Growth Tools: Mailerlite provides a solid set of growth tools at an accessible price. Landing pages are fully customizable with the drag-and-drop builder and include A/B testing capabilities. Signup forms come in multiple formats (embedded, pop-up, promotional) with trigger controls (time delay, scroll depth, exit intent). The platform includes a website builder for those needing a simple web presence. Automation enables subscriber tagging and segmentation based on behavior. What Mailerlite lacks is the sophisticated growth mechanics of Beehiiv (no referral program, no recommendation network). For newsletters where growth comes primarily from content marketing, SEO, and direct promotion rather than viral mechanics, Mailerlite's toolkit is sufficient and cost-effective.

Newsletter Features: Revue's editor focuses on content curation alongside original writing. The platform makes it easy to collect links, tweets, and media throughout the week, then compile them into newsletter issues. This curation-first approach works well for newsletters that summarize and comment on industry developments rather than publishing entirely original content. The editor supports standard formatting, images, and embedded tweets. Each newsletter generates a web archive accessible through your Revue profile or Twitter integration. The design options are limited compared to other platforms - you can customize colors and logos but not fundamentally alter the template structure. For straightforward, content-focused newsletters, this simplicity works; for brand-conscious publishers wanting unique designs, it's limiting.

Subscriber Management: Revue's subscriber management leverages Twitter integration as its differentiator. Your Twitter followers can subscribe with one click, and subscribers can choose to follow your Twitter account when signing up. The subscriber dashboard shows growth, engagement, and Twitter connections. Import subscribers from other platforms via CSV. Segment by subscription status (free vs. paid) and engagement level. Revue automatically handles unsubscribes and bounces. The Twitter integration creates interesting growth dynamics - your newsletter and Twitter presence reinforce each other. However, this also creates platform dependency - if Twitter changes policies or reduces Revue integration, your growth strategy might need adjustment.

Monetization: Revue supports paid newsletter subscriptions with a simpler fee structure than Substack. The platform takes 5% of subscription revenue (plus Stripe's standard fees), compared to Substack's 10%. Enable paid subscriptions, set your price, and gate content for paying members. Payment processing is handled through Stripe with automatic billing and subscription management. The lower take rate makes Revue attractive for newsletters focused on subscription revenue - at $10,000/month, you save $500/month compared to Substack. However, Revue lacks the sophisticated monetization options of platforms like Beehiiv (ad networks, boost programs) or Ghost (tips, multiple tiers, product sales). It's subscription-focused with limited flexibility.

Growth Tools: Revue's growth strategy centers entirely on Twitter integration. Your newsletter appears on your Twitter profile, making discovery easy for followers. Twitter's "Subscribe" button in your profile drives signups directly. You can share newsletter previews as tweets, building anticipation and social proof. The platform also supports embedded signup forms for external websites and basic landing pages. What's notably absent: referral programs, recommendation networks, SEO-optimized web archives, or sophisticated landing page builders. Revue assumes you're growing through your Twitter presence. For creators with established Twitter audiences, this integration is powerful. For those building audience from scratch or through non-Twitter channels, Revue offers fewer growth levers than alternatives.

Newsletter Features: Mailchimp's editor has evolved over two decades from simple email template builder to comprehensive campaign creator. The drag-and-drop builder includes dozens of content blocks, pre-designed templates, and custom HTML options. The Creative Assistant uses AI to generate designs based on your brand assets. Preview emails across clients and devices before sending. Schedule campaigns with timezone optimization. What makes Mailchimp frustrating for newsletter publishers is the interface complexity - features aimed at e-commerce, automation, and marketing campaigns clutter the experience when you just want to write and send a newsletter. The editor is capable but the overall experience feels heavier than purpose-built newsletter platforms.

Subscriber Management: Mailchimp offers extensive subscriber management features - perhaps too many for simple newsletter use cases. Audiences (formerly Lists) organize subscribers, with tagging, segmentation, and custom fields available at all plan levels. The platform tracks subscriber engagement, e-commerce activity (with integrations), and predicted demographics. Segments can combine dozens of conditions for precise targeting. Automation triggers based on subscriber behavior enable sophisticated journeys. The challenge is complexity: Mailchimp's power comes with a learning curve, and the interface has accumulated years of feature additions. For large, complex subscriber databases, this flexibility is valuable. For simple newsletter lists, it's overhead that purpose-built platforms avoid.

Monetization: Mailchimp isn't designed for newsletter monetization in the way Substack or Ghost are. There's no native paid subscription feature. E-commerce integrations support product sales, and you can link to external payment processors, but Mailchimp treats email as a marketing channel rather than a product. For SaaS companies where the newsletter supports product marketing rather than being a revenue source itself, this isn't a limitation. But if you're building a paid newsletter publication, Mailchimp adds friction that specialized platforms avoid. The platform has become increasingly aggressive about upselling additional features and services, which can be frustrating for teams wanting simple newsletter functionality.

Growth Tools: Mailchimp provides comprehensive growth tools reflecting its email marketing heritage. Landing pages with customizable designs and A/B testing. Signup forms in multiple formats with behavioral targeting. Social media advertising integration for audience building. Website builder for basic web presence. The platform's massive integration ecosystem connects to virtually any other tool you use. For growth, Mailchimp's advantage is ecosystem - it works with everything and supports marketing strategies beyond pure newsletter publishing. The disadvantage is that newsletter-specific growth features (referral programs, recommendation networks) are absent. Mailchimp excels when email is part of a broader marketing stack; it feels heavy when you just need a focused newsletter tool.

Newsletter Features: Campaign Monitor's strength is visual design. The drag-and-drop email builder produces genuinely beautiful emails that render consistently across clients. Template designs feel more polished and modern than most competitors. The editor includes responsive design tools that ensure newsletters look great on mobile. Custom HTML support gives designers full control when needed. Brand asset management stores logos, colors, and fonts for consistent application. For brand-conscious SaaS companies where newsletter design reflects product quality, Campaign Monitor delivers professional results. The tradeoff: less innovation in newsletter-specific features compared to platforms built exclusively for publishing.

Subscriber Management: Campaign Monitor provides solid subscriber management without unnecessary complexity. Lists and segments organize subscribers, with custom fields capturing additional data. Engagement scoring identifies your most active readers. The platform handles bounces and unsubscribes automatically, maintaining list hygiene. Import subscribers from major platforms with field mapping. What Campaign Monitor does well is making subscriber data actionable for design - you can personalize content based on subscriber attributes, creating tailored newsletter experiences. The platform integrates with CRMs and e-commerce platforms to enrich subscriber profiles with external data.

Monetization: Campaign Monitor, like Mailchimp, is designed for email marketing rather than newsletter monetization. There's no native paid subscription feature. The platform supports e-commerce integrations for product promotion and transactional emails. For SaaS newsletters where email supports product marketing, this isn't a limitation. For building paid newsletter publications, you'd need external payment processing and subscriber management - added complexity that platforms like Ghost handle natively. Campaign Monitor works best when your newsletter is a brand touchpoint rather than a standalone business.

Growth Tools: Campaign Monitor includes essential growth tools with a design-first approach. Signup forms are customizable and embeddable, matching your brand aesthetic. The platform supports landing pages for campaigns, though with less flexibility than dedicated builders. Analytics track subscriber acquisition sources, helping you understand what drives growth. Integration with advertising platforms enables coordinated campaigns across email and social. What's missing: viral growth mechanics like referral programs or recommendation networks. Campaign Monitor assumes growth comes through content quality, brand reputation, and marketing coordination rather than newsletter-specific growth hacking.

Newsletter Features: AWeber is one of the original email marketing platforms, and its newsletter features reflect decades of refinement. The drag-and-drop editor handles standard newsletter creation competently, with a library of templates, content blocks, and customization options. A Smart Designer feature can automatically generate branded email templates from your website URL. RSS-to-email automates newsletters from blog content. The editor isn't as modern as Beehiiv or as minimal as Buttondown, but it's reliable and well-documented. AWeber's long history means the platform has encountered and solved most common email challenges - it just works, without surprises.

Subscriber Management: AWeber uses a list-based subscriber organization with tags for additional categorization. Create multiple lists for different purposes, or manage everyone in one list with tag-based segmentation. The platform tracks subscriber engagement over time, identifying active and inactive subscribers for targeted campaigns. Automation (called "Campaigns") enables triggered email sequences based on subscriber actions. AWeber handles unsubscribes, bounces, and complaints automatically, maintaining deliverability. The subscriber interface feels dated compared to newer platforms but covers all essential functionality without confusion.

Monetization: AWeber's monetization features focus on e-commerce support rather than paid newsletters. Integrate with payment processors for product sales, create landing pages for lead magnets and purchases, and track e-commerce revenue in your dashboard. The platform doesn't offer native paid newsletter subscriptions like Substack or Ghost - you'd need external tools to manage recurring content payments. For SaaS companies using newsletters for marketing rather than direct monetization, this isn't a gap. For building paid newsletter businesses, more specialized platforms offer smoother experiences.

Growth Tools: AWeber provides fundamental growth tools without the sophisticated mechanics of growth-focused platforms. Landing pages are customizable through a visual builder. Signup forms come in multiple formats with targeting options. Web push notifications (a recent addition) extend your reach beyond email. The platform integrates with Facebook and Canva for cross-channel marketing. What's absent: referral programs, recommendation networks, or newsletter-specific viral features. AWeber's growth strategy assumes you're driving traffic through external channels (content marketing, SEO, advertising) and converting that traffic through reliable signup experiences. It's a solid foundation rather than a growth engine.
