The problem

Email deliverability depends on proper DNS configuration. Misconfigured MX records cause bounced emails, while missing SPF/DKIM records lead to spam filtering.

The solution

Use our DNS Lookup API to query MX records for mail server configuration, then check TXT records for SPF, DKIM, and DMARC policies. Validate email infrastructure before sending.

Everything this unlocks.

Verify MX records point to valid mail servers
Check SPF records for authorized senders
Validate DKIM and DMARC configuration
Prevent email deliverability issues
