Get notifications to mail when the allert changes status

[DaEMON-123]

Hello. Can you please help me set up a mailing so that emails only come when the status of the tracked page changes (I need to track the presence of raw html code, for example <h3><a>Ac</a></h3> on a landing page). Let me explain, when your service doesn't find a string in html, it sends a message to the mail and keeps sending them until the string is back in place. Often the problem can only be fixed after a long time, and we wouldn't want to clog up the mail with one-size-fits-all messages saying that there's an error on the site and the string we're looking for is missing. I would like to receive only 2 emails, one that the string is missing and one that the string is back. Thanks for your help.

uncheck "Send a notification when the filter can no longer be found on the page"
Won't completely do what you want but you won't get a ton of filter not found emails.

Alas, this completely invalidates the allert itself. Without this checkbox, I don't get a single email when the line I'm tracking is missing or changed.

Would checking “treat empty pages as a change” in global settings alert you when it disappears?
