Say we have a Pardot Prospect field 'Interests' and someone would update that field, either they themselves using a form or we do it through the Pardot UI (if we're on the phone with them).
Then how can I send out an email saying 'Thanks for updating your interests' every time they/we change that field?
I can use an automation rule, but that only matches once. So that does not cover the case when we update the field multiple times.
I can create a completion action on a form (which runs on every submit), but that doesn't cover the usecase that I change the 'Interests' field through the UI or the API etc.
Any other options?
