Resolving Duplicate User Entries in Mixpanel by Email Address

·

Hello everyone, we made a mistake when we used wrong userId (different one) for identifying users. Then we fixed it but now we have duplicate user entries in mixpanel. We also log e-mails, that are unique. Is there any possibility to tell mixpanel to join those accounts with same e-mail address? Or how would you approach solving this issue? Thank you very much in advance for any help, Filip

do you know what version of id merge you are on?

if you go to project settings, it should say there (we are on original ID merge)

depending on what you're on, you have different options

can you simply delete those profiles?

we have Simplified ID Merge

Do you think if I could call identify twice with old and new id? mixpanel?.identify("oldId"); mixpanel?.identify("newId"); Because what I have read, the alias is not possible to use for this Simplified merge ID

this is from the documentation:
It is not possible to merge 2 $user_ids together using the Simplified API. We don’t recommend doing this in general, as it adds complexity to your identity resolution strategy. Instead, we recommend having a single, unchanging $user_id for each user and pointing all other IDs for that user to that single $user_id
so I think you'll have to delete the duplicate profiles, and maybe delete and resend the associated events too, depending on your case
