“I have been using LeanMail for well over a year.”
I always had a pretty good control over my Inbox before, but LeanMail has helped me to optimize it even further. I especially like the archiving system which makes it much easier to find old Emails. Another feature that I appreciate is the LeanMail “Today” filter in the Inbox, which gives me a clear overview of what needs to be looked at and handled today. I highly recommend using LeanMail and am known to be quite a promoter for it.
