Frequently asked questions

What does Healthy do?

It runs all our checks on a domain at once (Whois, DNS, SSL, mail, blacklists, security headers, propagation on 500 resolvers) and produces a scored report you can share by link.

Why do I have to enter an email?

We send you the private link of the report and verify that the mailbox exists on the domain. The email does not appear in the public report and is not used for anything else.

How many checks can I run?

One per hour per IP address. A domain's report stays cached for 48 hours: anyone requesting it again gets it instantly.
