If you are hunting for a self hosted mailchimp alternative, you are probably tired of the same two problems: pricing that punishes you for growing, and zero real control over your own sending infrastructure. Mailchimp charges you per contact even when those contacts never open an email, and your deliverability is at the mercy of their shared IP pools and policies. Running your own email marketing platform on a VPS flips that around — you pay a flat server bill, you own your list, and you control your sending reputation. Below are the best self-hosted options that actually work in production, what each one costs, and what kind of server you need.
Why People Move Off Mailchimp
Mailchimp is fine until about 5,000 contacts. After that, the math gets ugly. Their Standard plan crosses $100/month fast, and you are still paying per stored contact, not per email sent. Then there are the softer frustrations: template builders that fight you, account reviews that freeze your campaigns at the worst moment, and deliverability that depends on a shared reputation you cannot see. A self hosted mailchimp alternative solves the cost problem completely — most of these tools are free and open source — but it trades money for responsibility: you become the deliverability team.
What You Need Before You Start
Every self-hosted newsletter tool needs a VPS with port 25 (SMTP) open. Most big cloud providers (AWS, Google Cloud, Azure) block outbound port 25 by default, which kills self-hosted email. Pick a provider known to allow it. For small lists, a 2 vCPU / 4 GB RAM / 50 GB SSD VPS is plenty; heavy Mautic installs with thousands of contacts benefit from 4 vCPU / 8 GB RAM. I have had good luck with Contabo for budget self-hosted mail servers — cheap, and port 25 access is straightforward to get — or RackNerd if you want a US-based VPS with solid network. Set up SPF, DKIM, and DMARC before you send a single campaign, or your mail lands in spam.
6 Best Self Hosted Mailchimp Alternatives
1. Listmonk — The Simple Workhorse
Listmonk is a single Go binary with a clean admin panel: import subscribers, build campaigns, track opens and bounces. Pro: dead simple to run — one binary, one Postgres database, tiny resource footprint. Con: no marketing automation or drag-and-drop builder; you write templates in HTML. Best for: newsletters and simple campaigns where you just want reliable sending without bloat.
2. Mautic — The Automation Powerhouse
Mautic is the closest thing to a free HubSpot: campaigns, lead scoring, segmentation, landing pages, email drip workflows. Pro: genuinely full-featured marketing automation at zero license cost. Con: resource-hungry (needs real RAM and cron tuning), upgrades can be painful, and the UI shows its age. Best for: marketers who need automation workflows and are comfortable maintaining a PHP/MySQL stack.
3. Postal — For High-Volume Senders
Postal is not a newsletter tool by itself — it is a full mail server (SMTP + webhooks + bounce tracking) that you pair with a frontend like Mautic or Listmonk. Pro: excellent delivery pipeline, message tracking, and it is built for volume (hundreds of thousands of emails a day). Con: it handles transport, not campaigns — you still need a frontend. Best for: senders who outgrew shared-SMTP relays and want their own serious sending engine.
4. Mailcoach — The Modern Laravel Option
Mailcoach (by Spatie) is a polished self-hosted newsletter app with a great campaign editor, subscriber segments, and automation. Pro: beautiful UI and excellent developer experience. Con: the self-hosted version is paid (~$99 for the code) — you buy it once, host it yourself. Best for: Laravel shops and people who want a premium experience without a SaaS subscription.
5. Sendy on Your Own AWS Account
Sendy is not open source, but it is a one-time $69 license that sends through your own Amazon SES account. Pro: dirt-cheap sending ($1 per 10,000 emails via SES), clean analytics. Con: no automation, and you are still partly dependent on Amazon's sending policies. Best for: high-volume newsletters where cost-per-email is the deciding factor.
6. Keila — The Privacy-Focused Newcomer
Keila is an open-source newsletter tool built with privacy in mind, with a solid campaign workflow and API. Pro: modern, lightweight, respects subscriber privacy by default. Con: smaller community and fewer plugins than Mautic. Best for: privacy-conscious senders who want a simple, modern newsletter app.
Total Cost Comparison
Here is the honest math for 20,000 contacts sending 4 campaigns a month. Mailchimp Standard: roughly $200–300/month. Listmonk + a $6–10/month VPS: under $15/month total (list free, server cost only). Mautic: $10–20/month for a bigger VPS, software free. Mailcoach: $99 once + ~$8/month hosting. Sendy: $69 once + AWS SES at about $8/month for 80,000 emails. The self-hosted route pays for itself within the first month at any serious list size — the real cost is your time setting up authentication and warming up your IP.
Key Takeaways

- Listmonk is best for simple newsletters; Mautic is best for automation; Postal + a frontend is best for high volume.
