What you give up vs Gmail / Google Workspace

  • Requires a dedicated server with proper DNS/PTR and good IP reputation
  • Not a bulk-newsletter tool — focused on mailboxes, not campaigns
  • Ongoing maintenance, updates, and spam tuning are on you
  • Resource-hungry; needs a few GB of RAM minimum

What you gain

  • • Full data ownership — self-host mailcow: dockerized on your own infrastructure.
  • • No per-seat SaaS bill (Gmail / Google Workspace: per-mailbox fees and data privacy).
  • • Open-source code you can audit and extend (GPL-3.0).
