How to identify users with different UUIDs but same email address?

Question

Is it possible to identify users with different UUIDs but the same email address in Braze? I can see that Braze recognises alias profiles but there is afaik no filter in the segmentation for this.

The goal is e.g. to stop the same user who has 2 UUIDs but the same email address from receiving an email twice.

Thank you in advance.

Hi @IoanaPa ! This is from the Braze Docs:

Braze automatically checks for and removes duplicate email addresses when an email campaign is sent. This way an email is only sent once and is “deduped” which checks that it doesn’t hit the same email multiple times even if multiple user profiles share a common address.

Because deduplication occurs when targeted users are included in the same dispatch, triggered campaigns (excluding API-triggered campaigns) may result in multiple sends to the same email address (even within a time period where users could be excluded due to reeligibility) if differing users with matching emails log the trigger event at different times.
