We would like to use Ad Bridge for re-targeting purposes but would need to hash the email addresses prior to them being pushed to FB.
We were told we need Web Personalization for the hashing feature but that doesn't make much sense.
Is anyone currently using AdBridge without Web Personalization and successfully hashing email addresses? If so, can you give a brief run down of how you are implementing this?
You can't hash the standard Email field in-place because you'll never be able to retrieve the original value.
You can push a hash of the Email to another custom field using using a webhook. Is that what you're aiming at?
Then your main objective is to be able to use hashes in the connector. It's not so much about having hashes generated and stored in Marketo -- that is relatively easy -- but about using those hashes in place of the standard Email field (and of course telling Facebook to match on hashes, since both sides have to know you're sending hashes!).
I have no idea if this is possible but suspect you will need a custom connector, not Ad Bridge proper.
