Mailamator is a self-hosted automation tool that wraps the Purelymail service in a friendly Flask-based interface, letting homelabbers and small-team admins manage their email infrastructure without manually clicking through dashboards or hand-editing DNS zones.

The tool tackles a very specific pain point: spinning up a new domain on Purelymail typically means juggling DNS records (MX, SPF, DKIM, DMARC) across your registrar, then provisioning mailboxes one by one through a web UI. Mailamator collapses all of that into a single dashboard. Based on its topic tags, it integrates with Cloudflare for DNS automation, ships as a Docker container for easy deployment, and supports bulk user creation — the kind of operation that's tedious but common when you're standing up email for a family, a small org, or a side project with multiple aliases.

What makes this interesting:

• It fills a real niche. Purelymail is a budget-friendly indie email provider beloved in the self-hosted community, but its API surface isn't exactly polished. Tools like this make it more approachable.
• It's built on a Flask + Docker + Cloudflare stack — familiar, hackable, and easy to fork for adjacent providers (Migadu, MXroute, Fastmail) with relatively modest changes.
• The bulk-user automation is genuinely useful at the homelab scale, where you might want twenty role-based addresses but can't justify enterprise IDM tooling.

Who would benefit: homelab operators running their own custom domains, small communities or families sharing a Purelymail account, and indie hackers who want to provision email infrastructure as code rather than as clicks. It's also a useful reference for anyone wanting to see how to glue together a registrar's DNS API with a mail provider's user API in a single Dockerized service.
