### 3/5 — Update please

*2022-03-28*

Update please

### 1/5 — Stopped working

*2020-01-21*

This worked great for a few days.  Now it insists that every message I submit to it is “Not Spam”.  You would think that I could make that decision a lot more effectively than the app or its backing web app...but no...it knows better.

The developer is not responsive.

Don’t waste your time and money.

**Developer response:** Hey Stevie.
I responded to your email and have followed up on this issue. As said, there is an update on the way. I’m sorry you feel this way as we are working hard on releasing a patch soon. Please bear with us.
