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
Common Causes
- Email service API key incorrect or not loaded
- Sender email not verified with service
- Email address invalid or bouncing
- Missing DKIM/SPF/DMARC records causing spam filters
- 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

Get HelpFrequently 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
