I switched to posteo. 1eur / month, does the job. Also use Thunderbird on mobile.
If people plan on switching my recommendation is not to do it all at once. Create the new email account and then slowly when you use accounts or buy something online point to the new account. It's also a good idea since you start a fresh email account to not give your email to just any random websites or services. For this I use firefox email relay that I also pay 1$ per month.
