I have switched to inbox.com after 15 years with Yahoo Mail. It takes forever to load, my emails are odd (format changes, saved drafts of stuff I sent), and the controls I used to use seem to be missing. Mainly, I’m tired of clicking on an email and waiting 10-15 seconds for it to display. They have ruined my favorite email...
I’m dismayed that you can no longer view messages in alphabetical order, which made it easy to sort through my inbox. And that ad on the right side of the screen—which you now have to pay money to get rid of—is annoying.
