Looking for an easy way to validate that your email is configured correctly? While technical compliance is only part of the deliverability equation (don’t forget our old friends reputation and engagement), it’s still very, very important to make sure you get it right: DNS configured correctly, authentication and headers, too. Sender Audit is a tool that can help you with that, and more! Created by Simon Bressier, this free web-based utility provides a comprehensive health check for your email sending infrastructure.
Sender Audit acts as a "pre-flight check" for your emails. By sending a single test message to a unique address generated by the site, the tool performs a deep-dive analysis of your technical configuration and content.
Authentication Validation: It verifies that your SPF, DKIM, and DMARC records are not only present but correctly configured according to the latest RFC standards.
Blacklist Monitoring: The tool automatically checks your sending IP and domain against major industry blacklists to ensure you aren't being blocked before you even hit "send."
Anti-Spam Filter Simulation: Using industry-standard engines like SpamAssassin and Rspamd, Sender Audit shows you exactly how recipient servers perceive your mail. It flags common issues like suspicious tracking pixels or formatting errors that trigger spam filters.
DNS Hygiene: It ensures your DNS syntax is perfect, helping you avoid the small technical "gotchas" that often lead to hard bounces.
Unlike some overly complex enterprise tools, Sender Audit is straightforward and fast. It gives you a clear "Pass/Fail" look at your deliverability health, making it an essential resource for small business owners, marketers, and mail administrators who want to ensure their messages actually reach their audience.
Head on over to the Sender Audit website to test your emails today!
