Jamie, what you're talking about is a form of the ​Counter Pattern ​in Marketo. Counters are used to count things taken off a stack -- those things can be registrations to a space-limited event, software trial keys, or, as in your case, sample packs or other physical offers -- it doesn't matter what the thing is, it's all the same concept. Unfortunately, counters aren't a true built-in feature, so we have to manage them in one of 2 ways: Using a special lead to represent the counter, which I call a ​Resource Lead. Whenever you use up a thing, send a form post (using a webhook) to that special lead that tells the lead to bump up a score field. Using a true counter in a remote database, also incremented (or decremented) via webhook. OK, so now you have a counter with the right count... somewhere out there. Then the question becomes, as I alluded to above, how to use that count to influence the display of a form.  Best destination (IMO) to store these options is a program-level {{my.token}}: have the webhook in (2) also update the program token via the Asset API when you go over a certain target count. But some people just manage the {{my.token}} by hand and have the webhook trigger an email ("Campaign Blah-Blah has used all its chits!") to remind them to change it. ... View more

For the flow use three "Remove from List" actions choose each of the three lists. This should remove everyone who received the email for each of your lists. ... View more
