What we check
SPF Authentication
Verifies the sending server is authorised to send mail for your domain, preventing spoofing.
DKIM Signature
Validates the cryptographic signature that proves the email has not been tampered with in transit.
DMARC Compliance
Checks that SPF and DKIM align with the From domain and that your DMARC policy is enforced.
Spam Score
Runs the email through SpamAssassin to predict how spam filters will treat it, with a breakdown of triggered rules.
Blocklist Check
Checks your sending IP against major email blocklists that could silently prevent delivery.
Content Analysis
Reviews subject line, links, and formatting for common patterns that cause emails to be flagged or filtered.
