If they convert, we update their custom attribute label to "converted" for only the one profile that they used when converting. Therefore, we can end up with one user having multiple profiles with the same email, where one is labeled "converted" and the rest are still leads. If we want to send a campaign or canvas to leads only, we may end up sending to a user's email that has actually converted but it wasn't labeled on all of their same-email profiles.Is there a way to filter out all profiles if one of them is already "converted" using the segmentation tool? So the logic would hopefully be something like: Filter out profiles that have an email that matches to an email in a "converted" profile. Let me know - thanks so much! Re: How to identify users with different UUIDs but same email address? Hi! I was running into the same problem but have a different issue that comes up from this aside from duplicate email sends. Say that of the two profiles that have the same email but different ID, one is labeled as "converted" with a custom attribute, and the other is still a "lead". Is there a way to filter out both profiles if one of them is already "converted" using the segmentation tool? So the logic would be something like: Filter out profiles that have an email that matches to an email in a "converted" profile
