What We Check

MX Records
Verifies mail server entries exist and route email correctly. Also detects RFC 7505 Null MX — when a domain explicitly declares it does not accept email.
SPF
Checks which servers are authorised to send email on behalf of your domain.
DKIM
Confirms that outgoing messages carry a valid cryptographic signature.
DMARC
Checks the policy that tells receivers what to do with unauthenticated mail.
MTA-STS
Ensures that receiving servers enforce TLS encryption for inbound email.
TLSRPT
Verifies that TLS failure reports are sent to a designated address.
BIMI
Checks if your brand logo is configured to display in supporting email clients.
DMARC Reports
Checks if aggregate and forensic DMARC reports are configured so you receive deliverability data.
PTR Records
Verifies that MX server IPs have correct reverse DNS entries to improve deliverability trust.
Blacklist
Spot-checks your primary MX server IP against 8 major spam blocklists including Spamhaus and Barracuda.
