Frustrating, unclear, and dishonest quota
The app measures quota in an unpredictable way, leading to portions of bulk messages, not being sent out, and it’s touted ability to pick up where it left off and resend them on the next quota period doesn’t actually work. Support is a bit of a joke, or you get a name and a picture of someone who looks unique, but then you get a boiler plate response that is just copy and paste it from their health page, which is rarely that helpful.
