Email Sending Fails - Emails Never Received

Emails aren't being sent. Email API returns success but users never receive the emails. Emails sent but marked as spam.

No error logs showing what went wrong.

Error Messages You Might See

Email sending failed - invalid API key Sender address not verified Invalid email address Email bounced - address unreachable Email marked as spam
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

Frequently Asked Questions

How do I verify sender?

In email service dashboard, verify sender email. Click confirmation link or add DNS records

What's DKIM/SPF/DMARC?

DNS records proving you own the domain. Prevents spoofing and improves delivery. Add in domain DNS settings

Why are emails going to spam?

No DKIM/SPF, OR content has spam triggers. Use templates, verify sender, add unsubscribe link
