Features
Everything for the infrastructure behind your mail
Six areas that work together. Use one, or all of them.
Blacklist monitoring
Check any IP or domain against the major DNS blocklists on demand, or let monitors re-check them around the clock and tell you the moment something changes.
Read moreSMTP and authentication testing
Connect to any public mail server and read the whole conversation, or send one message to your private test inbox and get a graded report on authentication and hygiene.
Read moreEmail validation
Check single addresses instantly or upload a list and get each address back with a clear reason: valid, risky or invalid.
Read moreDNS authentication
We generate the records for your domains, publish them through your DNS provider, check they propagated and keep watching for changes.
Read morePowerMTA servers
Give us a fresh server login and we install licensed PowerMTA, configure it with safe defaults, set up IP rotation and prove the setup with a test message, then clean up after ourselves.
Read moreDeliverability analytics
Turn your PowerMTA logs, DMARC reports and mailbox-provider data into charts and alerts that point at problems early.
