How this service works
Email domain routing check for Security review: Validate an email address shape and check whether its domain has MX records. DNS data only; does not send email or verify that an inbox exists.
Output
Returns whether the email address passes format validation and whether the domain has MX DNS records, indicating the domain is configured to receive email. No email is sent and no inbox is verified — results are DNS-only.
Example use cases
User onboarding email pre-screening
“Before I save this new user's registration, can you verify that the email address they entered — support@newstartup.co — is valid and that the domain is actually set up to receive email?”
CRM lead quality filtering
“I have a lead who gave me the email biz@techventures.io — can you check if the domain has MX records so I know it's a real, routable email before I add them to our pipeline?”
Security review of submitted contact email
“As part of our security review, check whether the email address admin@suspiciousdomain.net has a valid format and whether its domain has legitimate mail exchange DNS records configured.”
