Email Deliverability Checker
Get a 0–100 deliverability score with a prioritized list of fixes.
See how likely your email is to land in the inbox. The Email Deliverability Checker scores your domain's authentication and reputation out of 100 and shows exactly which signals are helping or hurting.
The Weighted Score
We combine the six most important deliverability signals into a single weighted score:
Each signal is graded and weighted, then rolled up into an A–F grade so you can prioritize the highest-impact fixes first.
Frequently asked questions.
Does a high score guarantee inbox placement?
No tool can guarantee the inbox, but strong authentication and clean reputation are the biggest controllable factors. This score reflects those.
Why is my score low?
The most common causes are a missing DMARC policy, no DKIM record, or a blacklisted sending IP. The report flags each one.
How is the score calculated?
We weight six signals — MX, SPF, DKIM, DMARC, BIMI, and blacklist status — and combine them into a single 0-100 score with a letter grade.
What's a good score to aim for?
Aim for grade A or B (roughly 85+) — this means your core authentication is solid and your sending reputation is clean.
How often should I re-run this check?
After any DNS or email provider change, and roughly once a month otherwise, since blacklist status and reputation can shift over time.
Does fixing one issue improve my score right away?
Yes — the score updates instantly on your next check once DNS changes propagate, typically within a few minutes to a few hours.
