Why is email verification not sending for new users?

Common reasons new-user email verification doesn’t send:
-
SMTP / mail provider not configured
- Missing or wrong SMTP host, port, username, password, or API key.
- The app may create the user, but email delivery silently fails.
-
Verification emails are disabled in settings
- Some auth systems require explicitly turning on “send verification email” for new registrations.
-
Email provider blocks the message
- Goes to spam, is rejected, or the sending domain is not authenticated.
- Check SPF, DKIM, and DMARC records if you’re using your own domain.
-
User account isn’t marked as requiring verification
- In some systems, only certain signup flows trigger verification.
- Social login or admin-created accounts may not auto-send it.
-
App logic never calls the verification function
- The account is created, but the code path that sends the email is skipped due to a bug or conditional.
-
Incorrect redirect / template / link settings
- Some providers require a valid callback URL or verification template setup before sending.
-
Rate limits or suppression lists
- The address/domain may be blocked because of too many attempts or prior bounces.
-
Environment mismatch
- Works in development but not production due to different env vars or service credentials.
