Decide whether Junipeer should also search for the matching Centra account by its account email.
Junipeer searches in this order: external ID (the company's ID in the other system), then VAT number (if Identify account by VAT number? is on). If no account is found:
Yes – Junipeer also tries to find the account by account email.
No – Junipeer doesn't search by account email.
Good to know
Billing email can be used as the last step. See Identify account by billing email?.
