CI Email Assertions
Send from the test suite, poll the API, assert on subject and body, then expire or delete the message fixture.
Poll for a message
Use a unique subject or plus-address tag per run. The mailbox message list supports q= search across subject, sender, recipient, and text body.
curl -H "X-API-KEY: $SMTPDEV_API_KEY" \
