Does anyone have any experience with the Durable Unsub function? I know the documentation says it works, but I'd like to verify if possible.
My company needs to clean up our DB by quite a bit and that will go a long way to doing it. Any other tips on that would be helpful, too.
Solved! Go to Solution.

Here is quick test you can use to verify that the durable unsubscribe option works. Create two test people in Marketo with the same email address. Run one of the people through a flow action updating the Marketo field "Unsubscribed" to "TRUE". The second person with the same email address who did not run through the flow action will also be marked as "Unsubscribed" to "TRUE".
If you are asking if it works i.e. have others experienced it? I can attest that I have and we rely on it to help us remain compliant as does a lot of other Marketo users.
The other posts provide some tips on checking this functionality and I recommend you test it for yourself if you have concerns.
Agreed, no one has ever reported it not working in my experience. It's part of the fabric of Marketo.
I had to send the durable unsubscribe through a whoooole battery of tests to prove it was working for GDPR purposes (including really odd edge cases for things like sending data between Marketo instances, honoring partial preferences, etc.) last year and couldn't find anything breaking aside from what I mention in . Confident that it works as intended.
