I need to know how emails are related to leads.
I am using the API and I need to know how they are related to perform the lead search by email.

I don’t know about the API, but try searching by a field called “email1”, usually that contains the primary email.

The full email information is more complex, it’s a one-to-many relationship to table email_preferences, since each person can have more than one email.
