About PlainMailer

Email operations should feel measured, not chaotic.

PlainMailer brings mailbox access, reputation warm-up, campaign scheduling and suppression controls into one self-hosted workspace.

Built for responsible delivery

The system is designed around practical safeguards: administrators control infrastructure, users only access assigned mailboxes, and the delivery queue applies the smallest available limit.

Provider policies and recipient consent still matter. PlainMailer supports operational controls; it does not guarantee inbox placement or replace the sending rules of your email provider.

Our principles
