I have been on the search for another larger and more developed email provider as a backup for instances when I can’t use my other emails because they are blocked by some services or an entity I need to interact with. Here’s a list of email providers I have managed to find for you:
cock.li (Vulgar, but has less vulgar domain name options, and they claim to be more transparent and honest, but I get some right-wing libertarian vibes from this service as I learned about it from Mental Outlaw (yeah, I know I watch some cringey tech channels, but I learn some helpful device from them, which is the only reason why I still watch them on occasion))
Fastmail (Proprietary, but they contribute to open source projects, and their JMAP standard project is pretty interesting)
Forward Email (Free/paid and open source, including the backend, and quantum-safe encrypted)
Maildrop (Free and open source throwaway email service)
Migadu (Proprietary, but built with open source software and has some open source repositories (GitHub), but forced free tier users to switch to a paid tier within one month during the pandemic)
MXroute (Proprietary, but built with open source software and has some open source repositories (GitHub))
Runbox (Proprietary, but built with open source software and has some open source repositories (GitHub))
systemli.org (Apparently it’s only available by invite link, and you have to be a leftist and know someone willing to give you an invite link)
Zoho Mail (Proprietary, but has some open source repositories (GitHub), have a good reputation, and also provides services such as an office suite, though their services are business oriented)
Keep in mind I haven’t done much research on these email services to be able to recommend them. I am posting whatever I find, and hopefully someone may be able to make a comment or you will be able to research more about them to see if they fit your needs.
I’m going to post this as it lists some email resources, testing tools, etc. even though the curated list is more intended for self-hosting email and email design:
Is there an email service that isn’t like this?
Tutanota mail is an alternative to Protonmail, but you can’t use another email client like Thunderbird. There’s some more options listed in this link:

As I suggested before, macaw.me offers free email, and monocles.de offers free and paid encrypted email (both use Roundcube webmail).
