Comments on Thunderbird (pre-2017)
“Mozilla free e-mail program – light and easy to use, manages all my email accounts” Debora Gallo
“Email may be dead, but my email client continues to be a place of constant activity. Most of our corporate communications come by email, as do the various mailings lists I subscribe to, comments and enquiries from people around the world, and more. Email remains my primary communications tool precisely because it is asynchronous – I prefer to send and receive messages on my own schedule.” Stephen Downes
