Postal is an open source mail delivery platform designed for teams preferring to manage their own infrastructure instead of relying on hosted services. It handles both outgoing transactional email and incoming mail, providing a self-managed alternative to SendGrid or Mailgun for organizations wanting full control.
It's best suited for teams with the infrastructure expertise and operational capacity to run their own mail servers. The open source model appeals to those prioritizing control and transparency over convenience.
