• If you are looking for a little bit of “extra” to go with your password manager, check out firefox relay. You can create emails that forward to your real email without exposing it. They allow you to block emails entirely, or just promotions. Their paid option is like $12/year (USD) and allows unlimited masks, and allowing you to create your own relay subdomain (like (whatever I decide)@dusty.mozmail.com). It’s definitely worth the relatively tiny charge for the paid version.

    There is also a relay service with Cloudflare but I’ve not tried it out yet. But having an email like 0tK8h384jkcxas@mozmail.com saved to my password manager is no big deal.
