ConvertKit (Kit) Alternatives That Won't Nickel-and-Dime Your List

Why founders look for ConvertKit alternatives

ConvertKit earned its popularity. When Nathan Barry launched it in 2013, it filled a gap: email marketing for independent creators who needed more than Mailchimp's basic newsletter but did not want the complexity of enterprise tools. The visual automation builder, simple tagging system, and clean interface made it the default recommendation in creator circles.

But several things have changed:

Pricing scales poorly for solo founders. ConvertKit charges by subscriber count: $25/month for 1,000 subscribers, $50/month for 3,000, $100/month for 10,000. That pricing made sense when ConvertKit was the only creator-focused email tool with automations. Now that MailerLite offers comparable features at roughly half the price and platforms like Brevo charge by send volume instead of subscribers, ConvertKit's pricing feels premium without a matching premium in features.

The Kit rebrand created confusion. The 2024 rebrand from ConvertKit to Kit confused existing users, broke some integrations, and made searching for help harder (searching "Kit email" returns irrelevant results). The rebrand was a branding exercise, not a product improvement — the platform underneath did not fundamentally change.

The free tier is restrictive. ConvertKit's free plan gives you 10,000 subscribers but limits you to broadcasts only — no automations, no sequences, no integrations. MailerLite's free tier gives you 1,000 subscribers with automations included. For a solo founder just starting out, MailerLite's free plan is more practically useful despite the lower subscriber cap.

Newsletter-specific tools have caught up. When ConvertKit launched, there were no newsletter-specific platforms with growth tools. Now Beehiiv and Substack both offer newsletter publishing with built-in audience growth features that ConvertKit lacks — referral programs, recommendation networks, and ad monetization.

Developer tools have leapfrogged. For technical founders, ConvertKit's API is decent but Resend's developer experience is in a different league. React Email templates, modern SDKs, and clean documentation make Resend the obvious choice for product-driven email.

How we evaluated these alternatives

Each tool was assessed through the lens of an indie founder who uses email as a core business channel:

• Cost at 1k, 5k, and 10k subscribers: The real monthly cost including features you actually need.
• Automation capability: Can you build welcome sequences, conditional logic, and behavior-based emails?
• Deliverability: Do your emails actually reach the inbox? (This is harder to measure but we looked at reputation data and community reports.)
• Developer friendliness: API quality, webhook support, and integration options.
• Migration path: How easy is it to move your list and automations from ConvertKit?

We specifically looked at the solo founder use case: one person managing their email marketing alongside building a product. Enterprise features like team roles, advanced permissions, and multi-brand support were not weighted heavily.

Deep dive: what each alternative does best

Buttondown — the minimalist's email tool

Buttondown is the opposite of ConvertKit in almost every way. Where ConvertKit adds features to serve more use cases, Buttondown removes features to serve one use case perfectly: sending a great email newsletter.

You write in markdown. You hit send. Your subscribers receive a well-formatted email. That is the core workflow, and Buttondown executes it with zero friction.

The markdown editor is fast and clean — no drag-and-drop blocks, no template browser, no AI writing assistant. If you write in markdown already (and most developer-founders do), this is the fastest path from draft to send. The preview shows exactly what your email will look like, and the formatting is consistently good across email clients.

The API is where Buttondown punches above its weight. Every feature available in the dashboard is available through a well-documented REST API. Subscriber management, newsletter sending, analytics retrieval, tag management — all programmatic. If you want to subscribe users from your app's signup flow, tag them based on their plan, and trigger a welcome sequence via API calls, Buttondown handles this cleanly.

Paid newsletter support uses a direct Stripe integration. Connect your Stripe account, set pricing, and Buttondown handles the subscription flow. No revenue share — you pay Stripe's standard fees and Buttondown's monthly subscription, nothing more.

What Buttondown does not have: a visual automation builder, landing pages, a website builder, drag-and-drop email templates, commerce features, or any of the marketing infrastructure that ConvertKit provides. If you need those things, Buttondown is not the right choice. If you find those things unnecessary, Buttondown is liberating.

Migration from ConvertKit: Export your subscriber CSV from ConvertKit and import into Buttondown. Tags transfer. Automations do not (Buttondown does not have a visual automation builder). If your ConvertKit automations are simple welcome sequences, you can recreate them using Buttondown's API or basic automation features.

MailerLite — the value champion

MailerLite is the recommendation I give to most solo founders who ask what email tool to use. It does not have the best automations (ConvertKit), the best growth tools (Beehiiv), or the best developer experience (Resend). But it does everything well enough at a price that makes the choice obvious.

The free tier is the most generous in this category: 1,000 subscribers with automations, 12,000 emails per month, signup forms, landing pages, and a website builder. You can run a real email marketing operation on MailerLite's free plan for months before needing to upgrade.

The visual automation builder covers the essential flows: welcome sequences, conditional branching based on opens and clicks, tagging based on behavior, and time-delay sequences. It is not as flexible as ConvertKit's automation builder for complex multi-path workflows, but it handles the bread-and-butter automations that 90% of solo founders need.

Landing pages and signup forms are included on all plans. The templates are decent — not designer-quality, but good enough for a lead magnet landing page or a newsletter signup popup. You can connect a custom domain to your landing pages, which is useful for building domain authority.

The email editor supports both drag-and-drop and rich text. The drag-and-drop editor has a solid selection of blocks (text, images, buttons, social links, dividers), and the templates, while not the most polished, are professional enough for a business email.

Where MailerLite falls short: the account approval process can reject certain niches (affiliate marketing, cryptocurrency, some financial topics). Advanced segmentation based on e-commerce behavior or custom events requires the Advanced plan at $20/month. And the community is smaller than ConvertKit's, which means fewer tutorials, templates, and integration guides.

Cost comparison at 5,000 subscribers: MailerLite Growing plan = ~$39/month. ConvertKit Creator plan = ~$79/month. That is $480/year in savings for roughly equivalent features.

Resend + React Email — the developer stack

Resend is not an email marketing platform. It is an email sending API. I am including it because a growing number of technical founders are building their email infrastructure with Resend instead of using an all-in-one marketing platform, and the approach has real advantages.

The pitch: design your email templates as React components using the React Email library, then send them through Resend's API. Your email templates live in your codebase, version-controlled in Git, written in a language you already know. No more clicking through a drag-and-drop editor or wrestling with inline CSS in a web-based template builder.

React Email is the companion library that makes this work. It provides React components for common email elements — <Button>, <Image>, <Section>, <Column>, <Link> — that compile to email-compatible HTML. The development experience is writing React, not writing email HTML. You get hot reloading, component composition, and TypeScript type checking on your email templates.

Resend handles the sending infrastructure: deliverability, domain authentication (DKIM, SPF, DMARC), dedicated IP addresses, and delivery tracking. The API is clean: a single POST request sends an email with your rendered React template.

The pricing model is per email sent, not per subscriber: $20/month for 50,000 emails, $100/month for 500,000 emails. If you have 10,000 subscribers and send two emails per week, that is roughly 80,000 emails per month — covered by the $20 plan. Compare that to ConvertKit's $100/month for the same subscriber count.

What you give up: everything. No subscriber management dashboard, no automation builder, no analytics beyond delivery status, no signup forms, no landing pages. You are building all of that yourself (or pairing with another tool). This is a deliberate trade-off for developers who want full control and are comfortable writing code for their email operations.

The practical stack: Resend for sending, your database for subscriber management, your app's event system for triggering emails, and React Email for template design. If that sounds like fun to build, Resend is your tool. If it sounds like unnecessary work, use MailerLite.

Beehiiv — the newsletter growth engine

Beehiiv approaches email from the opposite direction of ConvertKit. Where ConvertKit is an email marketing tool that can send newsletters, Beehiiv is a newsletter platform that has some marketing features. The distinction shapes everything about the product.

If you are a solo founder whose primary channel is a regular newsletter — you publish weekly or daily, your growth comes from the newsletter itself, and your revenue comes from subscribers or sponsors — Beehiiv is built for you. The referral program, recommendation network, and built-in ad marketplace are growth features that ConvertKit simply does not offer.

The referral system works: subscribers share your newsletter using a unique link, and when their referrals hit milestones you define, they earn rewards. This is the mechanic that powered the growth of Morning Brew and The Hustle, and having it built into your platform means you do not need to integrate a third-party referral tool.

The ad network is unique to Beehiiv. You can monetize your free subscribers by running sponsored content sourced through Beehiiv's marketplace. For newsletters with large free audiences, ad revenue can be meaningful — and it is a revenue stream that does not exist on ConvertKit, MailerLite, or Buttondown.

The website builder generates an SEO-optimized site for your newsletter that helps you capture organic traffic. Previous issues are indexed, individual posts have proper meta tags, and the site structure helps Google find and rank your content.

Where Beehiiv falls short compared to ConvertKit: email automation and segmentation. Beehiiv has basic automation (welcome emails, drip sequences) but nothing approaching ConvertKit's visual automation builder with conditional logic and behavior-based branching. If you need to send different email sequences based on what product someone bought, what link they clicked, or what tag they have, ConvertKit is materially better.

The decision: Are you a newsletter publisher who sometimes sells stuff? Pick Beehiiv. Are you a creator who uses email sequences to sell stuff and sometimes publishes a newsletter? Pick ConvertKit.

Loops — the SaaS email platform

Loops is the most narrowly focused tool on this list, and that focus is its strength. It is designed specifically for SaaS companies that need to send product-driven emails: onboarding sequences, activation nudges, trial expiration warnings, usage-based triggers, and lifecycle campaigns.

Where ConvertKit thinks in terms of subscribers, tags, and broadcasts, Loops thinks in terms of events, contacts, and journeys. When a user signs up for your app, that event triggers a welcome sequence. When they use a key feature for the first time, another event triggers a congratulatory email. When their trial is about to expire, the system sends a conversion-focused sequence. This event-based model mirrors how SaaS products actually work.

The interface is clean and modern — it feels like a SaaS product designed for SaaS founders, not a generic marketing tool with SaaS features bolted on. The email editor supports both visual design and HTML, and the templates are optimized for transactional and product emails rather than marketing newsletters.

Integration with your app is straightforward. Send events from your backend via API (user.signed_up, trial.started, feature.used), and Loops triggers the appropriate email flows. This is similar to what you could build with ConvertKit's API plus tagging, but Loops makes it the primary workflow rather than an afterthought.

The pricing reflects the SaaS focus: $49/month for 5,000 contacts on the Basic plan, $149/month for 25,000 on Scale. This is more expensive than MailerLite or Brevo at the same contact count, but the product-email-specific features — event tracking, lifecycle automation, transactional email support — justify the premium if your primary email use case is product communication.

What Loops does not do well: traditional marketing newsletters, creator-focused email marketing, digital product sales, or anything that is not SaaS lifecycle email. If you need both product emails and a marketing newsletter, you might end up running Loops alongside Buttondown or Beehiiv.

When Loops beats ConvertKit: Your email is about your product, not your content. You want event-driven automation, not tag-based automation. Your trial-to-paid conversion rate depends on well-timed emails triggered by user behavior.

Brevo — the budget all-in-one

Brevo (formerly Sendinblue) takes a different approach to pricing that makes it uniquely attractive for certain use cases: it charges by email volume, not subscriber count.

This pricing model is transformative for founders with large lists and moderate send frequency. If you have 20,000 newsletter subscribers but only send once a week, that is about 80,000 emails per month. On ConvertKit, 20,000 subscribers costs roughly $179/month. On Brevo's Starter plan, 80,000 emails per month costs about $35/month. The savings are dramatic.

Beyond email, Brevo includes SMS marketing, live chat (website widget), and a basic CRM — all in the same platform. For a solo founder who needs email, occasional SMS campaigns, and a simple contact database, Brevo consolidates three separate tools into one.

The automation builder is functional. You can create workflows triggered by email opens, link clicks, contact properties, dates, and custom events. It is not as polished as ConvertKit's visual builder, but it covers the standard automation needs: welcome series, abandoned cart, re-engagement campaigns, and date-based triggers.

The transactional email API is included alongside marketing features. If your app needs to send password resets, order confirmations, and shipping notifications alongside your marketing newsletters, Brevo handles both without a separate service like Resend or SendGrid.

The downsides are real. The interface feels cluttered — Brevo tries to be an all-in-one marketing suite, and the navigation reflects that complexity. Email templates look dated compared to newer platforms. And deliverability reputation is mixed — some users report consistent inbox placement, others report issues, particularly on shared IP plans. The dedicated IP option (available on Business plan and up) solves the deliverability concern but adds cost.

When Brevo makes sense: Large subscriber list, moderate send frequency, tight budget, and you also need SMS or CRM features. The volume-based pricing model is the most cost-effective option for lists over 5,000 subscribers that do not require daily emails.

When to stick with ConvertKit (Kit)

ConvertKit is still the right choice when:

• Complex automations are your growth engine. If your business depends on sophisticated multi-step email sequences with conditional logic, ConvertKit's automation builder is the most intuitive option on this list.
• You sell digital products via email. ConvertKit's built-in commerce feature lets you sell ebooks, courses, and memberships directly from emails and landing pages without a separate checkout tool.
• The creator ecosystem matters to you. ConvertKit has the largest community of independent creators sharing templates, strategies, and integrations. That ecosystem has real value for learning and networking.
• You are already invested. If your automations, integrations, and workflows are deeply embedded in ConvertKit, the migration cost (rebuilding automations, re-tagging subscribers, reconnecting integrations) may exceed the savings of switching.

The premium pricing is worth it if you actively use the features that justify it. If you are only sending broadcast newsletters and not using automations, you are paying for capabilities you do not use — and a cheaper tool would serve you better.

Migration tips for founders

1. Export everything first. ConvertKit lets you export subscribers with tags, custom fields, and subscription dates as CSV. Do this before you start the migration.
2. Map your automations. Document every ConvertKit automation (triggers, conditions, actions, emails) before attempting to recreate them elsewhere. Screenshot each automation flow.
3. Migrate subscribers in batches. Import a test batch of 100 subscribers to your new platform first. Send a test email. Verify deliverability, formatting, and unsubscribe links work.
4. Run both platforms in parallel. Keep ConvertKit active for two weeks after switching. Forward new signups to both platforms during the transition.
5. Warn your subscribers. Send a brief email letting subscribers know you are updating your email setup. Ask them to add your new sending address to their contacts. This protects your deliverability on the new platform.
6. Expect some list hygiene. During migration, you will discover inactive subscribers, invalid emails, and duplicates. Take this as an opportunity to clean your list — smaller, engaged lists have better deliverability and lower costs regardless of platform.
7. Track your conversion rate for a month after switching. If open rates or click rates drop significantly, investigate deliverability issues before assuming the new platform is worse.
