Release 2127
Trello card
Context
We want to improve candidate attendance, and think sending them additional SMS reminders might help.
Changes proposed in this pull request
- Split notify jobs and despatchers into SMS and email
Guidance to review
I thought we could get this base code merged, then add the SMSs in a separate PR.
Note: everything related to "despatch" is spelt that way already throughout, I think its just ye olde
