Verification Emails Never Arrive: Replit Email Config Chaos

The communication breakdown

Critical emails aren't reaching users, causing confusion and frustration. Password resets fail, verification emails disappear, and important notifications never arrive. Your support team is overwhelmed with "I didn't get the email" tickets while users abandon the signup process.

How AI misconfigured email delivery

AI tools often generate basic email code without proper configuration for production environments. They might use localhost SMTP settings, skip SPF/DKIM authentication, or fail to handle delivery failures properly. The code works in development but fails silently in production.

The email rescue

1. Configured proper SMTP settings for production
2. Implemented SPF, DKIM, and DMARC authentication
3. Added delivery status tracking and error handling
4. Set up email queue processing for reliability

The delivery success

Email delivery rates improved from 40% to 98%. Users now reliably receive verification emails, password resets, and notifications. Support tickets about missing emails dropped to near zero, and user signup completion rates increased significantly.
