How this service works
Audit email deliverability for a domain — checks SPF, DKIM, DMARC, MX records (POST variant)
Output
Returns a structured audit report for the specified domain covering SPF record validity, DKIM configuration, DMARC policy presence and enforcement, and MX record setup — indicating which checks passed or failed and likely issues affecting email deliverability.
Example use cases
Troubleshoot customer email delivery failures
“Our customers say they're not receiving order confirmations from sales@ourcompany.com. Can you audit our domain's email setup and tell me what might be causing delivery issues?”
Verify domain before launching campaign
“We just acquired a new domain for our marketing team and want to send out a big campaign next week. Can you check if the domain has all the right email authentication records set up properly?”
Debug spam folder deliverability problems
“A lot of emails from our support team are ending up in Gmail spam. Can you run a full audit on our domain to see if there's something wrong with our DKIM, SPF, or DMARC configuration?”
