Anyone using Revue Newsletter?

My client wants a newsletter feature, and I recently saw Twitter promoting a new acquisition of theirs called Revue.

This Axios article states the free version of Revue has a 50 recipient limit that increases to 40,000 for $5/month.

However, the paid version is currently in private beta.

Just signed up, but am wondering if anyone has tried using Revue and what their experience has been like. At $5/month it seems the price can’t be beat.
