Free Email Deliverability Test
Test the DNS and transport signals that affect email deliverability, including SPF, DMARC, DKIM, MX records, STARTTLS, and policy strength.
Frequently Asked Questions
What does an email deliverability test check?
This test checks the domain-level signals mailbox providers inspect before accepting or trusting email: authentication records, inbound mail routing, encryption, and DMARC policy posture.
Is this the same as sending a test email?
No. A send-based seed test checks inbox placement from a specific campaign. This domain test checks whether your DNS and transport setup gives campaigns a strong foundation.
What is a good deliverability score?
A strong domain should have SPF, DKIM, DMARC, MX records, STARTTLS, and ideally a DMARC policy moving toward quarantine or reject after reports confirm legitimate senders.
