Using Usernames Instead of Emails for Profile Integration

Hi Khushi L., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so.

Yes, you can use a unique user identifier instead of an email. However, the identifier you choose should be unique to each user and should not change. For example, a database ID could be used. While using an identifier like email may be more convenient, keep in mind that you cannot merge 2 $user_ids or change a $user_id, so if the user changes their email, they will count as a separate user. In terms of stitching to the profile, User Profiles are set directly on $distinct_ids, not on $user_ids or $device_ids. It is recommended to wait until after a user is identified before setting user profile properties. However, for certain integrations like Facebook Ads, Google Ads, and Iterable, you must set an email as a user profile property or have a device advertising ID. In addition to an email address, Mixpanel sends the first name user profile property, the last name user profile property, a phone number user property, an advertising ID user property and a distinct_id.

Yes, it would still work. You can use an email ID as the $user_id in Mixpanel. However, it's important to note that if a user changes their email, they will count as a separate user because you cannot merge 2 $user_ids or change a $user_id. Also, for certain integrations like Facebook Ads, Google Ads, and Iterable, you must set an email as a user profile property. Remember, User Profiles are set directly on $distinct_ids, not on $user_ids or $device_ids. It is recommended to wait until after a user is identified before setting user profile properties.
