Consider a Signal group or some sort of backup comms channel.

Edit: Email can have latency, which is why I did not recommend it.

Email is always there as a backup, but no one in the company uses it anymore, to the point where we have to remind people to check it incase an external vendor reaches out.

Slack has provided so much additional functionality that trying to cram day to day working back into email just doesn't work anymore.
