Email sending failed - invalid API keySender address not verifiedInvalid email addressEmail bounced - address unreachableEmail marked as spam

Common Causes

  1. Email service API key incorrect or not loaded
  2. Sender email not verified with service
  3. Email address invalid or bouncing
  4. Missing DKIM/SPF/DMARC records causing spam filters
  5. Email content flagged as spam

How to Fix It

Check API response: email services return delivery errors

Verify sender email: must be verified in email service (SendGrid, Mailgun, etc.)

Check spam folder: legitimate emails might land there

Configure email records: DKIM, SPF, DMARC in DNS for higher delivery

Test email: send to own mailbox first, check content for spam triggers (ALL CAPS, many links)

Use verified templates: pre-written email templates have better delivery
