Fewer surprises, less time spent checking.
Most small businesses only find out something is wrong when a customer tells them. KT8 checks for you, explains what it found, and tells you what to do about it.
Email that lands
Find out why emails go to junk, prove who is allowed to send as your domain, and spot anyone pretending to be you.
Mail tester · DMARC reportsA fast website
See how quickly your pages load around the world, what slows them down, and which fix will help most.
Speed testNothing expired
We watch your domains, certificates and email records, and email you before a renewal date or a change catches you out.
My domains · DNS checkerNothing broken
Every page crawled for broken links, missing pictures and old redirects, with the page and the link text to fix.
Link InspectorEvery site and domain on one screen.
Speed, email health, DNS, broken links, DMARC and renewal dates for each of your sites, with the things that need you at the top.
