Yes, Airmail is still supported, but IMHO its UI suffers from severe feature creep. I also found it never reliably notified me that account passwords needed to be changed. I used it against MS Outlook, and whenever the password on the backend needed to be changed after 60 days, Airmail would simply sit there and not receive any new emails.

I didn't initially notice your privacy policy because there doesn't seem to be a link from the Mac app page. I had to go to the homepage by deleting the path from the URL in my browser, since I couldn't find a link to the main page on the Mac app page. I scrolled to the bottom of the page, as that's where these things usually are, but all I found was a trio of social media buttons. I scrolled back up and noticed the three-horizontal-lines symbol, which I correctly assumed would bring up a menu. I found the privacy policy under that.

I can only speak for myself, but I would have found it valuable to have an obvious link to the privacy policy on every page. I really wanted to find the privacy policy, because I felt a bit guilty about how tersely worded my previous comment to you was. Had I not been so motivated, I might have just looked at the page, thought it looked nice, then closed it when I couldn't find an obvious link to a privacy policy.

Anyway, thanks for answering my question. I hope I didn't come across as rude. I feel like a parent sending my kid to a sleep-over. I just want to make sure my data will be safe while it stays with people I don't know.
