A Cron-Friendly Email Smoke Test for Staging

Short summary

Treat email verification as a narrow scheduled smoke test instead of a full end-to-end suite, testing one action per run with isolated mailboxes to prevent state pollution. Verify critical elements like subject, recipient, call-to-action link, and send timing while keeping implementation small and reproducible. This pattern catches real failures users experience—wrong environment links, delayed delivery, duplicate messages—without the maintenance burden that makes teams abandon complex test suites.

• •Use isolated, disposable inboxes per test run to avoid state confusion and false negatives
• •Assert one message type per run with minimal, focused assertions on critical elements
• •Schedule via cron every few hours rather than running on every PR to keep tests maintainable
• •Keep implementation small and boring; the goal is catching regressions, not building infrastructure
