The Comms module can only send out bulk SMS/App Messages/emails to recipients who are on the ScholarPack system as either a student contact, or as a staff member.
Although only existing contacts can receive bulk messages, individual email addresses can be added to the recipient list of a bulk email communication by entering their email addresses manually in the "Email directly" text box:
If you need to send the message to more than one individual email address, you can separate them with a comma and a space (e.g: example01@email.com, example02@email.com).
You will not be able to save the bespoke contact list to ScholarPack, however you can always save your list of additional email addresses to a Word document so that you can copy and paste them over each time you need it.
