Two-way
SMS messaging
in Slack channels
Finally, a way to manage all your SMS messages in one place.
No more personal phone numbers, no more chaos.
Just a piece of advice. I used my personal cell number as the company number and I still regret it a decade later (I get so many stupid calls). Don’t do what I did.
