- An orange/red arrow appears on any communication sent directly to that particular person. So when viewing a guardian's communications log, a red arrow means the email was sent directly to them, regardless of whether or not the message arrived successfully.
- A green arrow appears next to a communication sent by that person, such as a guardian replying to an SMS the school sent.
- No arrow means the communication was sent to someone linked to the user. For example, an SMS that was sent to their child's other guardian. They appear in this guardians communications log because they relate to that guardian/the student despite not being directly sent to them.
Arrows will be different colours in different places, for the same communication. So for an email sent from the school to a guardian, the arrow will be green on the whole-school communication log, and orange on the guardian's communication log.
