### This is potentially a common need..
because Fibery email integration feature creates a new Contact database, and likely users have their own Contact database already, and want to synchronize contacts between these databases.
### Formula?
Is it possible in a fibery formula field to find and link two entities of two separate databases if they both have fields that contain the same email address?
### Text vs Email type field
The use case is that I have a fibery Email integration database ‘Contact’ and another contacts database ‘Contact’ from another space. I want to automatically synchronize contacts with a one-one relationship between the databases. Both contain a a field ‘Email’, although I see that the integration database does not utilize the email field type, but just a text field for it.
### GraphQL
I tried with scripting and graphql but am still learning that and a few hours later it did not work yet.

Have you tried using a 1:1 auto-linking relation?
