Mail Tester

Mail Tester provides a fast, technical check of an email message and its sending setup to help identify deliverability and spam-related issues. Send an email to the unique test address shown on the site and Mail Tester analyzes the message content, server configuration, DNS records and sending IP to produce a readable report with a spam score and diagnostic details.

Key capabilities:

• Spam scoring and content analysis using established filters to highlight elements that increase spam risk.
• Automated checks of authentication records (SPF, DKIM) and common DNS/mx configuration errors that affect delivery.
• Sender/IP reputation and basic header inspection to show how receiving servers may evaluate the message.
• Clear, itemized report that flags problems and shows which checks passed versus failed, making technical issues easier to prioritize.
• Rapid, one-shot testing workflow that requires only sending a single message to the provided test address to receive results.

Benefits:

• Helps diagnose why emails land in spam or are rejected by recipients’ servers by combining message and infrastructure checks.
• Useful for developers, deliverability engineers, and marketers who need a quick verification of authentication and basic server setup.
• Saves time compared with manual inspection of headers and DNS records by consolidating common deliverability tests into a single report.
• Produces actionable findings suitable for troubleshooting or handing to an IT/admin to resolve configuration problems.
