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.

Is Sender Audit free?

Yes. The full email analysis is free with no account required. Creating a free account unlocks scan history, domain monitoring and real-time alerts.

How do I test my email deliverability?

Send an email to the unique address generated on our homepage. Within seconds, you receive a detailed report with a score out of 100 covering authentication, security, reputation, content quality and compliance.

Does Sender Audit help with Google and Yahoo compliance?

Yes. We check all requirements for bulk senders: DMARC authentication with alignment, List-Unsubscribe header with one-click support, proper SPF/DKIM setup, and low spam complaint rates.

What is continuous domain monitoring?

With a free account, your domains are scanned every 48 hours, and every 12 hours from the Pro plan. You receive instant alerts when DNS records change, IPs get blocklisted, SSL certificates near expiry, or DMARC/TLS-RPT reports arrive.

Is Sender Audit a spam checker?

Yes. Every analysis runs your message through SpamAssassin and Rspamd, the two engines used by a large share of receiving servers. The report details each rule triggered and its impact on the score, so you can fix it before sending.
