Essential Zoho Mail Setup Instructions

  1. Generate an Application-Specific Password: Zoho blocks standard passwords for SMTP connections. Go to Zoho App Passwords (or accounts.zoho.com), generate a password named "Retatrutide Checkout", and copy the 16 characters into ZOHO_PASSWORD.
  2. Ensure Outgoing SMTP is Enabled: In your Zoho Mail Control Panel, navigate to Mail Accounts > User Details > Mail Configuration and verify that SMTP Access is switched ON.
  3. Matching Sender Address: The ZOHO_EMAIL address must match your authenticated Zoho user or an authorized sending alias.
