The choice today

Owning your email usually means giving up the automation.

Leave a rented platform for your own server and something usually stays behind. The rented platforms keep the automation and your list. The free self-hosted tools send to a whole list, with no flows. The full open-source suites take a team to keep running.

Rented platforms keep the list.

Kit, Klaviyo and Mailchimp run the automation, but your list and history stay on their servers, and the bill grows with every subscriber.

Free tools stop at the newsletter.

listmonk sends to a whole list, with no multi-step flows. A welcome series needs your own scheduler.

Heavy tools need a team to run.

Mautic needs PHP, MySQL or MariaDB and cron jobs before the first email goes out.

How it works

What it takes to self-host Mimeo.

  1. Step 1: One server

    Mimeo is one Rails app with one SQLite database. No PostgreSQL, MySQL or Redis. Hatchbox on DigitalOcean is the documented path; any Rails host works.

  2. Step 2: Your domain and your sender

    Point your Mimeo's domain at the server with HTTPS, connect your Postmark or Resend account, and add one CNAME record per sending domain.

  3. Step 3: Your list and events

    Import your list and your opt-outs by CSV, then send events from your site, store or app to start flows.

Own your sending

Manage your own sending. Really.

Mimeo is your email marketing software where you manage your list, automations, and emails. It plugs into your own sending account. You pick one provider: Postmark or Resend.

The obvious question: what about deliverability and list health? Deliverability is your sending provider's whole job. That's what they're for. Mimeo keeps your side of the street clean, automatically.

  • Every send is checked before it goes out: verified sender, unsubscribe links, suppression list.
  • Bounces, complaints, and unsubscribes are cleaned up the moment they happen.
  • Big sends are paced: spread over hours at a rate you set, never blasted.

Your direct line to your customers' inboxes.
Now in your control.

Lowest cost · simplest setup. The developer-favorite email API. Verify your domain, paste one API key, and you're sending.

Questions

Self-hosting questions, answered.

What running your own email software takes.

What does self-hosted email marketing software need to run?

For Mimeo: one server that runs a Rails app with HTTPS and a stable domain, one SQLite database, and a Postmark or Resend account for sending. Deploy Mimeo has the requirements.

How does Mimeo compare with other self-hosted tools?

Mimeo has multi-step flows on any event and agent access; listmonk is a good free pick if you don't need flows, and Mautic suits a team that wants a large marketing suite. How Mimeo compares to alternatives has the sourced facts.

Is Mimeo open source?

No. Mimeo is a commercial license you buy once for one installation. It runs on your server, and your data stays in your database.

Can someone set it up for me?

Yes. Setup & Launch is $999 on its own or $1,399 with the license: we deploy Mimeo on your server, connect your sender, authenticate your domain and import your list. Get in touch.

Is there a hosted version?

No. Mimeo is self-hosted only, so your list never sits on our servers. If you don't want to run a server, a rented email platform is the better fit.

Email automation you own, on your own server.

Owning your email shouldn't mean giving up the automation. Mimeo keeps both: flows on any event, sequences, broadcasts and segments, in one app with one SQLite database.

Your list and its history live in your database, and your own Postmark or Resend account sends every email.

Buy it once for your installation. Stop renewing support & updates, and Mimeo keeps working.
