I would suggest that one volume picks up, it will become impractical to monitor in this way anyway.
I would recommend thinking about these channels in the same way as you do voice. You don't have someone verifying every word an agent says on the phone before the customer hears it, to ensure that there are no words or sentences which are not appropriate to say which impacts the Company's image. Instead you fundamentally trust your agents to be professional, but verify this through recordings and evaluations of a sample.
If you truly want Supervisors to control the outbound messaging, you may as well have them reply to the customers themselves.
Just my 10 cents.
