Check your domain's deliverability score in seconds. SPF, DKIM, DMARC, and more — with the exact DNS fixes to reach the inbox.
Why this matters
Major providers check SPF, DKIM, and DMARC before delivery. A misconfigured domain gets flagged silently — your newsletters, receipts, and notifications disappear without a bounce.
Without DMARC enforcement, anyone can send email from your domain. Phishing campaigns impersonate you, your customers get scammed, and your sender reputation tanks.
One misconfigured record can break your entire email setup overnight. Without monitoring, you find out from a customer complaint — days or weeks later.
The score
We score every domain from 0 to 100 based on how well your email authentication is configured. Higher scores mean better inbox placement.
0 – 20
Emails are likely being rejected or spam-filtered by major providers.
21 – 40
Serious gaps — deliverability is unreliable and spoofing risk is high.
41 – 60
Setup is incomplete — emails may land in spam intermittently.
61 – 80
Solid foundation. Minor fixes can maximize inbox placement.
81 – 100
Fully optimized. Maximum inbox placement and domain trust.
