It recently came to my attention that Gmail is using my (and others) emails to train their AI to provide "overviews" for email threads. I didn't find that in any of the recent Agreement changes so feel safe is stating Alphabet/Google never obtained my permission for this training. I'm not a fan of the far-flung use of AI and the mounting examples of how horrendously Google AI performs hasn't done anything to relieve my concerns. I began a search for a better, reliable email client and there is a depressing shortage of them that fulfill the average email users' needs. Thunderbird looks pretty good but reading through the Help section, Community Forum questions and just general articles hasn't clarified a couple of questions I have. 1. Is Thunderbird a comprehensive email client, independent of other clients, or does it provide service by partnering with another client? 2. Does Thunderbird utilize AI for any purpose that requires the "review" and storage of individual users' emails? Many thanks, MarilynB 2019 MacBook Pro
