When processing credit cards in the BBMS Virtual terminal, one of the available fields to complete is for email address.
In the Card Not Present section of BBMS the email address is a required field. However, this is not a required field when processing a credit card in the Card Present section. If processing a Card Not Present transaction you can enter any address in the Email field. The email address does not get checked and no email is sent to the address. (Tip: If the donor does not have an email, enter an email like DonorHasNoEmail@yoursitename or NoEmailKnown@yoursitename to record that one was not known at the time of processing.)
