When a customer replies to an email from our support channel, their reply includes all the previous replies, making the comment history cluttered. Here's an example from "testy mctester" in which I only want to see the "Try Again" comment. We want to limit having customers make an account and respond via a portal, we would rather make the emailed responses the most accessible way for them.
I've tried using the email regex and automation rules, but there can be issues where we exclude important information like attachments.
