> Thunderbird is one of the few in a dying category I reluctantly agree. I think that the continuing relevance of email is largely a consequence of open standards and interoperability - things that Google et al are getting less and less keen on. As well as Thunderbird allowing me to have a copy of my emails on my desktop/laptop, rather than in someone's cloud, I think its good to have an open-standard success story to point to. But in reality I use the Fastmail web client on desktop and Fastmail's app on my Android devices. Despite using Thunderbird for over a decade, nowadays I really only use it to sync a local email archive. I wish it were otherwise.
