What email provider do you use for shopping and corporate spam?

[ladybugs@lemmy.world]

I'm trying to de-Google, and that means finally getting off of Gmail. I need a new email address for shopping/corporate spam. Where should I park all the emails I get about coupons, shipping updates, new product features, policy changes, etc.?

Considerations:

-I don't want to just give all my shopping data to another big AI company. (So, not Outlook/Microslop.) I don't want a provider that will sell my data to third parties, either. These emails don't need top-level privacy protection, but random third parties don't need to know whether I buy cheap or expensive shoes.

-I'd like to use email aliases for different companies so I can figure out who's the leak if I start getting emails from an unexpected source. (Although maybe that can be a separate service from the email provider?)

-I don't care what country the email provider is based in. I don't care if the CIA can theoretically find out what shoes I buy, I just don't want businesses giving me higher "personalized" prices because of those shoes.

-I'd prefer to stick with a free email provider if possible, but maybe that's not compatible with the first point, IDK.

Suggestions, please!
