Mailchimp Alternatives That Don't Charge You for Unsubscribed Contacts

Why founders look for Mailchimp alternatives

Mailchimp's origin story is indie to the core. Ben Chestnut and Dan Kurzius bootstrapped it from 2001 to a $12 billion acquisition by Intuit in 2021. For years, the generous free tier (2,000 subscribers, 12,000 emails per month) made it the obvious first email tool for any bootstrapped founder.

Post-acquisition, the economics shifted. The free tier dropped to 500 contacts and 1,000 emails per month. Paid plans crept up in price. The interface accumulated features — website builder, social media posting, CRM, postcards — that most email-focused users never asked for. Finding the email campaign builder now requires navigating through a dashboard full of cross-sell prompts.

The most frustrating change is how Mailchimp counts contacts. Unsubscribed contacts and cleaned (bounced) contacts still count toward your plan limit unless you manually archive them. A list of 2,000 subscribers where 300 have unsubscribed and 100 have bounced shows as 2,400 contacts on your bill. You pay for people who cannot receive your emails.

The alternatives below take different approaches. Some compete directly on features and price (MailerLite, Brevo). Some focus on specific use cases (ConvertKit for creators, Loops for SaaS, Resend for transactional). Some strip email down to its essence (Buttondown). All of them charge more honestly than Mailchimp's current pricing model.

How we evaluated these alternatives

We looked at each tool through the lens of a solo founder sending email to grow their product or content:

• Price per subscriber: What does it actually cost at 1,000, 5,000, and 10,000 subscribers?
• Time to first send: How fast can you go from signup to sending your first email?
• Deliverability: Do emails actually reach the inbox, not the spam folder?
• Automation: Can you set up welcome sequences, abandoned cart emails, or drip campaigns?
• Data portability: Can you export your subscriber list and email history if you leave?

We did not weight CRM, social media posting, or website building features. Those are distractions from the core job: sending email that people open and read.

Deep dive: what each alternative does best

ConvertKit (Kit) — the creator's email tool

ConvertKit has spent a decade building specifically for content creators — newsletter writers, podcasters, course creators, and indie founders who build audiences through content. The focus shows in the product.

The visual automation builder is ConvertKit's strongest feature. You map subscriber journeys as flowcharts — someone signs up, they get a welcome sequence, if they click a specific link they get tagged and enter a different sequence. It is intuitive to build and easy to debug when something is not working. Mailchimp has automations too, but they feel like they were bolted onto a platform that was not designed for them.

The tag-based subscriber system is fundamentally different from Mailchimp's list-based approach. In Mailchimp, a subscriber who signs up for two different lead magnets exists in two lists and counts twice. In ConvertKit, a subscriber exists once with multiple tags. This alone can cut your effective subscriber count (and bill) significantly.

ConvertKit includes landing pages and opt-in forms, which reduces tool sprawl. You do not need Leadpages or a WordPress plugin for lead capture. The built-in Creator Network — a cross-promotion feature where newsletter writers recommend each other — is a genuinely useful growth channel that has no equivalent in Mailchimp.

The trade-off is email design. ConvertKit deliberately keeps email templates simple. Plain text emails with minimal formatting outperform designed emails for most creators, and ConvertKit leans into that philosophy. If you need pixel-perfect HTML emails with custom layouts, ConvertKit's editor will frustrate you.

Best for: Content-driven founders who want visual automations, tag-based segmentation, and built-in lead capture.

Buttondown — the minimalist's newsletter

Buttondown is a newsletter tool built by Justin Duke, a solo developer who also works at Stripe. It does one thing: let you write and send newsletters. The editor supports Markdown. The subscriber management is straightforward. The analytics show opens, clicks, and unsubscribes. That is it.

For a founder who writes a weekly newsletter — updates about their product, industry commentary, technical tutorials — Buttondown is perfect. You write in Markdown (the same format you use for documentation and READMEs), preview the email, and send. No template gallery to browse, no drag-and-drop blocks to arrange, no AB test to configure.

The RSS-to-email feature is underrated. If you have a blog, Buttondown can automatically send new posts as newsletter editions. Write once, distribute to both web and email without manual effort.

Paid newsletter support works through Stripe with no additional transaction fees from Buttondown. For creators monetizing through subscriptions, this is cleaner than Mailchimp's paid newsletter implementation.

The limitations are real. Automation is limited to basic sequences — you cannot build the complex branching workflows that ConvertKit offers. The free tier caps at 100 subscribers, which most serious newsletters outgrow in their first month. And because Buttondown is a one-person operation, support responsiveness depends on Justin's availability.

Best for: Developer-founders and writers who want a simple, fast, Markdown-native newsletter tool without any feature bloat.

MailerLite — the value champion

If you need a full-featured email marketing platform but do not want to pay Mailchimp prices, MailerLite is the answer. It covers the same ground — drag-and-drop email editor, automation workflows, landing pages, opt-in forms, subscriber management — at roughly half the cost.

The free tier is genuinely generous: 1,000 subscribers with 12,000 emails per month, including automation. Mailchimp's free tier gives you 500 contacts and 1,000 emails with no automation. MailerLite's free plan alone is more capable than Mailchimp's paid Essentials plan in several areas.

The email editor is good. Not as polished as Mailchimp's, but it loads fast, the drag-and-drop blocks work intuitively, and the template library covers common layouts. The automation workflow builder handles sequences, conditional splits, and time-based triggers — everything most indie founders need.

The approval process is the biggest complaint. MailerLite reviews every new account to prevent spam, and the process can be strict. Some legitimate senders get rejected, particularly if your website is new or your use case is not immediately clear. If you get rejected, contacting support with more context about your business usually resolves it.

Deliverability is generally solid for engaged audiences but can struggle with cold or semi-engaged lists. If you are sending to subscribers who opted in and actually want your emails, MailerLite performs well. If you are importing a purchased list or emailing people who signed up years ago, you may see more spam folder placement.

Best for: Budget-conscious founders who need the full email marketing toolkit at the best price-to-feature ratio.

Loops — email for SaaS builders

Loops is different from everything else on this list because it is built specifically for SaaS products. It combines marketing email with transactional email and product-triggered messages in one system.

The key insight: in a SaaS product, the line between "marketing email" and "transactional email" is blurry. An onboarding email is technically marketing but feels transactional. A trial expiration reminder is transactional but also a sales nudge. Loops treats all of these as part of one messaging system triggered by product events.

You send user events from your app to Loops (user signed up, user activated, trial expiring, user churning), and Loops triggers the right email based on the event and the user's current state. The automation builder is designed around this product-event model rather than the traditional marketing funnel model.

The modern UI is refreshing if you are coming from Mailchimp's cluttered interface. Everything is clean and purposeful. The API documentation is thorough and the TypeScript SDK is well-built.

The pricing gap is the problem. Free up to 1,000 contacts, then $49/month for up to 5,000. There is no $10-20/month tier for small but growing SaaS products. If you have 1,500 contacts, you are paying $49/month — the same as ConvertKit's Pro plan for a product with far fewer features outside the SaaS-specific use case.

Best for: SaaS founders who want marketing and transactional email in one platform, triggered by product events, and can justify the pricing.

Brevo — the multi-channel workhorse

Brevo (formerly Sendinblue) tries to be the marketing platform that does everything: email, SMS, WhatsApp, chat, CRM, meeting scheduling. For a solo founder, most of that is noise. But two things make Brevo genuinely interesting.

First, pricing by email volume instead of subscriber count. If you have 5,000 subscribers but only email them twice a month, Brevo charges you for 10,000 emails — which starts at $9/month. Mailchimp would charge you for 5,000 subscribers regardless of how often you email them. For infrequent senders, the savings are significant.

Second, transactional email is included. Every Brevo plan, including free, includes a transactional email API. You can send password resets, order confirmations, and receipts through the same platform that handles your newsletters. This eliminates the need for a separate tool like Resend or Amazon SES.

The email editor shows its age. It works fine, but it lacks the polish of Mailchimp or MailerLite. The template library is adequate but not inspiring. The overall interface can feel overwhelming because Brevo keeps adding features (CRM, phone system, push notifications) that clutter the navigation.

Deliverability reviews are mixed. Some users report excellent inbox placement. Others report issues, particularly with Gmail. Your experience will depend on your sending volume, domain reputation, and list quality.

Best for: Founders who send email infrequently (volume-based pricing saves money), need transactional email included, or want SMS marketing alongside email.

Resend — the developer's transactional email

Resend is not a Mailchimp alternative in the traditional sense. It handles transactional email — password resets, receipts, notifications — not marketing campaigns. It is on this list because many founders use Mailchimp's Mandrill add-on for transactional email and need a replacement.

The developer experience is excellent. The API is clean and well-documented. The TypeScript SDK works seamlessly with modern frameworks. Domain verification with DKIM and DMARC is guided step-by-step. Sending an email from your app takes about 10 lines of code.

The React Email library is the standout feature. You build email templates as React components using JSX syntax, preview them locally, and deploy them with your application code. If you are already building with React or Next.js, email templates become part of your codebase instead of a separate tool.

Delivery speed is fast. Most emails arrive within 1-2 seconds of the API call. For time-sensitive transactional email (two-factor codes, password resets), this speed matters.

Resend is built on AWS SES infrastructure, which means deliverability depends heavily on your domain reputation. A new domain with no sending history will need a warmup period. An established domain with good reputation will see excellent inbox placement.

Best for: Developer-founders who need transactional email with a modern API and want to build templates in code.

The deliverability factor

No matter which tool you pick, deliverability depends more on your practices than your platform. The basics:

• Authenticate your domain: Set up SPF, DKIM, and DMARC records. Every tool on this list guides you through this. Skip it and your emails go to spam.
• Clean your list: Remove bounced addresses and unengaged subscribers regularly. A smaller, engaged list delivers better than a large, stale one. Watch your churn rate on subscribers.
• Warm up gradually: If you switch platforms, do not blast your entire list on day one. Start with your most engaged subscribers and ramp up over 2-3 weeks.
• Write emails people want: The best deliverability hack is sending content that people open and click. High engagement signals to email providers that your messages belong in the inbox.

When to stick with Mailchimp

Mailchimp still makes sense if:

• You are already running complex automations that would take significant effort to rebuild
• You use Mailchimp's Mandrill integration for transactional email alongside marketing campaigns
• Your team has non-technical marketers who know the Mailchimp interface well
• You need the most polished email template editor on the market (Mailchimp's is still the best)

The switching cost is real. Migrating subscribers, rebuilding automations, updating opt-in forms on your website — budget a full day for a simple migration and a week for a complex one.

Making the switch: practical advice

1. Export your subscriber list first. Download a CSV from Mailchimp with email addresses, tags, and custom fields. Every alternative can import CSV data.

2. Document your automations. Screenshot or write down every automation workflow in Mailchimp before you start rebuilding them in the new tool.

3. Update your DNS records. Remove Mailchimp's SPF and DKIM records and add the new provider's records. Overlapping authentication records can hurt deliverability.

4. Send a test campaign from the new tool to your most engaged segment first. Monitor open rates and deliverability before migrating your full list.

5. Update opt-in forms and integrations. Any form on your website, landing page, or app that connects to Mailchimp needs to be reconnected to the new provider.

6. Keep Mailchimp active until migration is verified. Do not delete your account until you have confirmed the new platform is sending and delivering properly. Most tools offer parallel sending during the transition.
