Key points
  • The org has been inviting people from its Thundermail waitlist to try the service through an early-access program, and this writer just happened to be among them.
  • Yes, Thundermail is a paid service, which may put off some users who are used to free email accounts offered via Gmail, Outlook.com and Proton Mail, but with the first two of those you do get served ads along with your messages.
  • Firefox and the Thunderbird mail client both recently moved to a fortnightly release schedule in line with Mozilla’s plans, and Thunderbird itself gained support for Microsoft’s Exchange late last year.

Now known as Thundermail (what else?), the service was originally developed under the Thunderbird Pro banner, which encompassed paid email, appointment scheduling, and file-sharing services designed to generate additional revenue for the organization.

Additional details
  • Thundermail offers a web-based email interface and can also be accessed through the Thunderbird desktop app, the Thunderbird mobile app for Android, or other compatible email clients.
  • A welcome screen introduces you to the features of Thundermail, which include the ability to work on several drafts at once, schedule delivery times for emails, create folders to arrange messages, contact lists and identities – all pretty much standard for an email system.
  • This is roughly equivalent to the £55 we paid for a year on the early access program.
  • The web-based user interface of Thundermail presents a fairly clean and uncluttered look, and could be likened to Gmail with the screen partitioned into a pane with folders on the left and a larger one to the right displaying messages.
  • We haven’t really had the time to test out Thundermail a great deal since signing up, but there are no great surprises so far, and everything works pretty much the way you would expect it to.
