Where each falls short

The honest trade-offs — what you give up with each, versus the proprietary tools they replace.

AcyMailing
  • Tightly coupled to Joomla/WordPress ecosystem
  • Advanced automation features gated behind paid plans
  • No standalone deployment outside a CMS
Mail-in-a-Box
  • Requires a dedicated Ubuntu VPS with a clean IP reputation; shared hosting is not supported
  • No built-in bulk mailing or newsletter campaign tools
  • Limited horizontal scalability; single-server architecture only
  • Webmail (Roundcube) is functional but far less polished than Gmail's UI

Bottom line

Both are a similar lift to self-host; choose Mail-in-a-Box for the larger community and ecosystem. Mail-in-a-Box has seen more recent development. Open each guide below for deploy steps and the full feature gap.
