Upsert a contact record by email

Update an existing record or insert a new contact record using the email address that you specify using the following logic:

  • If the email address exists in the list, only the first record matching that email address is updated with the data you provide.
  • If the email address is not already in the list, a new record is added.

Please take note that this means that any duplicate records are NOT updated.
