How can you test spam score before sending?

Testing spam scores before sending helps identify potential issues that would cause filtering problems. Several approaches are available depending on your technical resources.

Mail-Tester.com is a popular free option. Send your test message to their unique address, then view the detailed analysis showing spam score, authentication results, and content issues.

GlockApps and similar services provide professional-grade testing with spam scores across multiple filters plus inbox placement testing at major providers.

For technical users, running a local SpamAssassin instance lets you test messages directly and see exactly which rules trigger points. This is particularly useful for high-volume senders optimizing content.

Many ESPs include built-in spam checking that flags potential issues before campaigns launch.

Test before you sail. A pre-voyage inspection reveals problems when they are still easy to fix.
