How to Email score checker

Published October 16, 2024 · Updated July 16, 2026 · Email Security

An email score checker rates how likely your messages are to reach the inbox - before you send to your whole list. It scores content, authentication, and reputation, then tells you what to fix. Here is how to use an email score checker to protect your deliverability.

What it measures

Spam-trigger content - risky words, formatting, and links.
Authentication - whether SPF, DKIM, and DMARC pass.
Reputation - your sending IP and domain standing.
Technical setup - reverse DNS, list hygiene, and more.

How to use it

Send a test message to the checker's address, then read the report. A high score means you are inbox-ready; a low score comes with a checklist of exactly what to fix.

Biggest lever: most low scores come from authentication and IP reputation, not wording. Fix SPF/DKIM/DMARC and send from a clean IP first.
