Hey Chris -
To avoid being black listed due to sending emails to hard bounces, you can set Email Invalid to True. That way you won't be able to send them emails - at least not from Marketo. Here is some information on Munchkin:
Hi Christian (apologies for calling you Chris - I think it's because I saw the response from Chris) -
No. First of all - that's a trigger that is listening for Marketing Suspending gets changed to True. It's not setting anything. Secondly that's the Marketing Suspended field (which also prevents Marketo from emailing the person if set to True - unless it's an operational email). I was talking about the field called "Email Invalid" - and changing it to True would be in the Flow and would look like this:
I'm not sure my organization is using [Munchkin].
If you're not, you should be.
As the others have explained, Munchkin is Marketo's web analytics feature, which tracks Clicks Link on Web Page and Visits Web Page activities. If you see those activities in leads' Activity Logs, you're using Munchkin. And since web engagement can continue long after an email address can't be emailed anymore, you must consider this factor before deciding a lead is dormant. You could even have an ongoing SMS relationship with someone after their email address is dead. That's not a lead that should be deleted!
Interesting discussion and example of management. I'm working on some clean up management at the moment, too.
Do you really delete all bounced emails?
If you're on a shared IP and another Marketo customer sends some bad mailings and the IP gets a bad reputation, you will also remove all emails which will be bounced because of Hard Bounce/Spam blocking?
I like your automated management/flow, but I would add a constrain to trigger "bounce email" and add "category 2". All other bounces I would keep in database and review before deleting.
