I agree and that's what I meant by Google's "web apps" having promos about Gemini.

But in terms of accessing Gmail accounts via the IMAP protocol in Mozilla Thunderbird, Apple Mail client, etc, there are no spam emails about Gemini AI. Google could easily pollute everybody's gmail inboxes with endless spam about Gemini such that all email clients with IMAP access would also see them but that doesn't seem to happen (yet). I do see 1 promo email about Youtube Premium over the last 5 years. But zero emails about Google's AI.
