I must say, SendHub and co have done a pretty remarkable job. Their product is superb, I highly recommend just trying it to see how to do onboarding on a fairly complex service (considering multiple people & phones are involved).
Thank you for the kind words Bryan!
I love the shared groups concept. I always thought there would be a lot of benefit for small local businesses to benefit from group messaging.
SendHub seems like a great way to make that happen.
