Use simulation mode to test your site’s email-sending flows without contacting a real provider.

Turn it on

Go to BooleanSMTP → Settings.
Under Testing & Content, turn on Email Simulation Mode.

While it’s on, every outgoing email is recorded to Email Logs, under the Simulated tab, instead of being sent — nothing reaches a real inbox.
