QA Testing With Temporary Emails

Use temporary emails to validate signups, verify flows, and test email deliverability without polluting real inboxes.

Why Use Temporary Emails for QA?

  • • Rapidly generate disposable addresses for repeated test cycles
  • • Avoid rate limits and duplicate-account conflicts on staging/prod
  • • Keep personal and team inboxes clean and compliant
  • • Reduce PII exposure in screenshots, logs, and bug reports

Common QA Scenarios

Signup & Verification

  • • Verify email confirmation links and codes
  • • Test rate limiting and resend flows
  • • Validate edge cases (expired links, reused tokens)

Transactional Emails

  • • Password reset, welcome, receipts, and receipts retry
  • • Rendering checks for HTML/plain text and dark mode
  • • Link tracking: UTM presence, correct destinations

Test Plan Checklist

  1. Generate a new temporary address for each test case
  2. Trigger email flow and capture the inbox state with timestamps
  3. Open, validate content, links, and rendering variants
  4. Verify bounce, resend, and expiration behaviors
  5. Document results and attach sanitized screenshots

Best Practices

  • • Separate test categories with different addresses to simplify triage
  • • Use unique identifiers in display names/subjects for quick filtering
  • • Keep the inbox tab open during tests to avoid missed messages
  • • Store expected email templates and compare programmatically if possible
