What does Sender Audit check?

Sender Audit performs 40+ checks on your email including SPF, DKIM, DMARC, BIMI, DNSSEC, MX records, TLS/STARTTLS encryption, MTA-STS, IP & domain blocklists, spam score (SpamAssassin + Rspamd), content readability, subject line quality, image accessibility, broken links, tracking pixels, and Google/Yahoo bulk sender compliance.

Does Sender Audit help with Google and Yahoo compliance?

What is continuous domain monitoring?

With a free account, your domains are scanned every 12 hours. You receive instant alerts when DNS records change, IPs get blocklisted, SSL certificates near expiry, or DMARC/TLS-RPT reports arrive.
