Automatically tag incoming tasks via email?

While I love Trello for working collaboratively with clients, the way it handles notifications is terrible. Can anyone think of a way to automatically tag and file an incoming task with OmniFocus (or Things3 or…) so that I can dive into a client project and see the updates they’ve sent, without getting bogged down in the other notifications that just don’t matter right now.

I’m also up for a workflow (shortcut) that I can run on my Inbox in iOS, since I’m actually 99% iOS for everything I do.

Email rules are your friend here, you will need to write the rule to sort the good from the bad yourself, but then you can use the omnifocus mail drop to get them auto added into Omnifocus.
