Overview

Coolify is a self-hostable PaaS (a self-hosted Heroku/Vercel) that makes deploying services on your own server almost one-click — which is exactly why it's a great home for a self-hosted email stack. This guide is about the architecture of an email stack on Coolify specifically: which of its services fit, how they connect, and the gap you still fill yourself. (For picking tools, see best email marketing tools for Coolify.)

What runs on Coolify, and how it connects

Coolify's one-click catalog and Docker support let you deploy the sending and list layers in minutes: useSend as your sending app (it's a documented Coolify service), Listmonk for newsletters, Mautic or Plunk if you need them. Coolify provisions the databases and handles deploys, SSL, and updates, so you skip most of the Docker plumbing a Docker stack would require.

These apps still relay delivery through Amazon SES — Coolify hosts the application, not the mail-server reputation. So the connection shape is: Coolify-hosted useSend → SES → the inbox, with your domain authenticated.

  • useSend as a one-click/Docker Coolify service
  • Listmonk / Mautic / Plunk if you need lists or automation
  • Coolify handles databases, deploys, SSL, updates
  • Apps still relay through Amazon SES

What Coolify doesn't do

Coolify deploys the apps; it doesn't do deliverability or workflow. You still configure SPF/DKIM/DMARC, exit the SES sandbox, wire SNS for bounces, and warm the domain — the part teams assume "one-click" covers. And the one-click catalog has no shared reply inbox, AI drafts, or unified campaign-plus-reply workflow.

That workflow gap is where Mailbase fits: point it at your Coolify-hosted useSend (BYO at €5/mo) and the team gets campaigns, a shared reply inbox, analytics, and suppression on delivery you fully own — or run Mailbase on managed sending if you'd rather not host. See how to deploy useSend.

  • Still yours: SPF/DKIM/DMARC, SES sandbox exit, SNS, warmup
  • No shared reply inbox or AI drafts in the catalog
  • Mailbase adds the workflow layer on your Coolify useSend

Common Mistakes

  • Assuming “self-hosted” means plug-and-play — DNS and SES work remain.
  • Forgetting the SES sandbox exit and SNS bounce/complaint wiring.
  • Self-hosting the app but expecting it to fix IP reputation for you.
  • Skipping the workflow layer and stitching five tools together by hand.

FAQ

Can I run an email marketing stack on Coolify?

Yes — Coolify deploys the sending and list layers (useSend, Listmonk, Mautic, Plunk) as one-click or Docker services, provisioning databases and handling deploys and SSL. They relay delivery through Amazon SES, and you still handle DNS authentication and deliverability yourself.

Does Coolify handle email deliverability?

No — Coolify deploys the applications, but you still configure SPF/DKIM/DMARC, exit the SES sandbox, wire up SNS bounce/complaint notifications, and warm the domain. "One-click" covers the app, not the IP reputation or DNS work.

What's missing from a Coolify email stack?

The workflow layer — a shared reply inbox, AI-assisted drafts, and unified campaign-plus-reply handling aren't in the one-click catalog. You either build it or add a workflow layer like Mailbase pointed at your Coolify-hosted useSend instance.
