I had the opposite vibe. Had the same process went through the call and they asked what I needed and wanted from an email client and after telling them they said that it probably wasn’t for me yet. And I didn’t sign up.

They emailed me when features I mentioned were added and then a couple of years ago tried again. Been using it everyday since then as my primary email driver at work.

They know they have a niche product - a paid email client; an expensive one at that! So they filter so word of mouth and reviews and all match expectations and make sure their product is a good fit. It has been the opposite of scammy.
