FAQ
MX Record Lookup questions
Why do MX records matter?
MX records tell other mail servers where to deliver mail for a domain.
What if no MX record appears?
The domain may not be configured for mail, or it may rely on fallback A or AAAA routing that should be reviewed carefully.
Can I use this with the Email Validator?
Yes. Run the Email Validator when you want to combine MX status with syntax and verification signals for an address.
