You pay that for every Slack user, no matter how many or few messages you exchange with them. I don't think someone else is going to pay $6.67 to replace ten email messages.

"I frequently interact with at least 25 people just to do my job"

Frequently, not ten messages in total.

Email works fine for non important sporadic communication.
