Replacement scope: Self-hosted mailing lists and campaign/transactional sending

Keep
When you should keep paying for Mailchimp
- If you're on an older plan, check your actual bill before comparing — grandfathered pricing can beat every list price here.
- Mailchimp's integration ecosystem is still the broadest in this comparison and Standard's 200 flows are enough for many automation setups.
- Under the free caps (250 contacts, light sending) there is little practical pressure to move.
Before you switch
Switching boundaries
- Templates, automations and signup forms are rebuilt in every candidate — no importer carries Mailchimp automations over.
- Sender reputation and warmed sending domains do not transfer automatically; expect a re-warm period with any new provider.
- Listmonk means running your own server plus a delivery infrastructure (IP reputation, ESP relay) — the license is free, the operations are not.
Rebuild
Rebuild it yourself instead?
A modest email sender with signup forms, segments, and a few automations is a multi-day build on an email API. Mailchimp's weight is deliverability at massive scale, a polished editor and templates, automation, and a large integration ecosystem.

FAQ
Questions people ask before switching
What is the best free Mailchimp alternative?
Depends on your shape: MailerLite Free (250 subscribers, 2,500 sends, 3 automations) for the same audience size as Mailchimp Free; beehiiv Launch (2,500 subscribers, unlimited sends) for newsletters; Cal-style unlimited is not on the table here — every hosted option meters something.
Is anything cheaper than Mailchimp?
Three pricing models compete: per-contact (Mailchimp, ActiveCampaign), per-subscriber-tier with usage caps (MailerLite) and flat/self-hosted (Listmonk at $0 license). At 1,000 contacts, ActiveCampaign Starter ($15/mo annual) undercuts Mailchimp Standard ($20/mo promo) while adding deeper automation.
Which Mailchimp alternative has better automation?
ActiveCampaign — automation-plus-CRM is its core product. MailerLite includes 3 automations on free and unlimited on paid; beehiiv has none on its free plan.
Is there an open-source Mailchimp?
Listmonk: AGPLv3, single binary plus Postgres, Docker deployment, lists with SQL segmentation, transactional sends. Self-hosting the software is free; reliable delivery (IP reputation, relay) is the real cost. Mautic adds marketing automation at higher ops complexity.
Can I move my subscribers?
Yes, with friction: MailerLite offers a guided switch, an API-key import and a free done-for-you migration service; beehiiv imports CSV subscribers plus Mailchimp campaign content; ActiveCampaign's import path is unverified here; Listmonk takes CSV. Automations never carry over.
Does Mailchimp have AI?
Yes — generative AI features ship as a no-extra-cost add-on on Standard and Premium only; Free and Essentials don't include them. Checked on the official pricing page, Oct 2, 2026.
Will AI just write and send my emails?
No. Every AI in this category assists — subject lines, drafts, send-time optimization. Strategy, list hygiene, deliverability and judgment stay with you. Pages claiming otherwise are marketing.
