Channel aware customers & users (email address conflicts)

[BeepLoveKarki]

In a proper multivendor store, we need customers and users aware of channel, but in our case if we use same email address across multiple channels, same user is returned, updated, deleted.

Please suggest some easy way to tackle this right now!!!

And hope vendure makes it auto tackled in future release.

I am interested in this specific feature also. I am trying to build a multi tenant solution where multiple channels can have the same customer with the same email. Maybe there should be an option to change the matching strategy to usernames instead of emails?

In my opinion, this functionality makes perfect sense, and we would like to ask whether you plan to include it in future releases. For organizations running multiple projects on a single backend, this feature is crucial—especially if the individual channels do not operate under a single domain.

We would prefer the ability to differentiate customers based on their email addresses within individual channels, as email is the standard identifier today, while usernames are becoming less commonly used in practice.
