Two complementary tests
Placement test
Send an email to our seed addresses and see whether it lands in the inbox, the Promotions tab or spam on Gmail and Outlook.
Authentication audit
Real-time DNS analysis of your SPF, DKIM and DMARC records. The foundations of good deliverability.
Blacklist check
Find out whether your server's IP or domain is listed on the major blocklists: Spamhaus, Barracuda, SORBS, SpamCop, CBL.
How it works
- 1
Enter your email
We create a test session and give you around ten seed addresses across Gmail, Outlook and other providers.
- 2
Send your test email
From your usual sending tool, send one email to those addresses, keeping the unique identifier in the subject line.
- 3
Read your score
We detect the placement in each mailbox and compute a deliverability score out of 10, with improvement tips.
Why test your email deliverability?
Deliverability measures your emails' ability to reach the inbox rather than the spam folder or the Promotions tab. An unauthenticated email (missing SPF, DKIM, DMARC), sent from a recent domain or a blacklisted IP, gets filtered by Gmail and Outlook before it is even read. This free spam checker gives you a clear diagnosis and concrete levers to improve your inbox placement rate.
