We'll check
Your results will appear here
Enter your domain on the left and hit check
01
Email authentication
SPF, DKIM, and DMARC determine whether receiving mail systems can verify that your messages are authorised.
02
Sending reputation
We check your sending IP against public reputation lists used by Gmail, Outlook, and Yahoo.
03
Domain reputation
Domain age and other signals affect how new sending domains are treated by mail providers.
04
Real email test
Send an actual message and we'll inspect its authentication results and subject line automatically.
This tool checks deliverability signals — not whether a specific email will land in any particular inbox. Inbox placement depends on many factors beyond DNS configuration.
