Test your email deliverability with a detailed spam score analysis. Check SPF, DKIM, DMARC, SpamAssassin, content quality, and IP reputation.

An email deliverability tester analyzes your outgoing emails against the same criteria that spam filters use to decide whether to deliver your message to the inbox, send it to spam, or reject it entirely. Instead of guessing why your emails aren't reaching subscribers, you get a concrete score and specific issues to fix.
This tool checks your email against 15+ criteria across authentication, IP reputation, spam content analysis, and technical best practices. Unlike simple SPF/DKIM checkers, it receives your actual email via SMTP — the same way Gmail, Outlook, and other providers receive it — giving you the most accurate picture of how your emails are perceived.
SPF, DKIM, and DMARC prove your emails are legitimate. Missing authentication is the #1 cause of inbox placement failure.
Up to -4.0 points for failures
If your sending IP is on a blacklist like Spamhaus, your emails will be rejected by most providers before content is even checked.
Up to -3.0 points for listings
SpamAssassin and content analysis check for spam patterns, suspicious links, image-heavy layouts, and other red flags.
Up to -3.0 points combined
Email authentication is a set of DNS-based protocols that verify the identity of email senders. Without proper authentication, your emails can be spoofed by anyone and most providers will either reject them or send them to spam.
Use the SPF Checker, DKIM Checker, and DMARC Checker for in-depth analysis of each protocol.
v=DMARC1; p=none is better than nothing, but p=quarantine or p=reject is recommended.
