Bulk adding email addresses to Online Express signup form

Danielle Allen 2

Because we can't add custom fields to the OLX signup form, we are going to have to create a Google form and then manually enter the email addresses that give us permission to do so (to comply with Canadian anti-spam laws) - does anyone know if there is a bulk function for doing this? We would need the confirmation email to be sent to each address so that users can opt in.
