Yes, all these email services want you to pay up for them. I think this is the price tag for privacy.
I have switched to Mailbox org a couple of years ago. I had a freemail provider before that. Unfortunately, this providers’ data got leaked, and therefore I got pwned, luckily only resulting into a tsunami of spam. The entry-tier with Mailbox is 1 € per month (= 12 € per year) which is compareably cheap in my opinion. Of course, it depends on what features you desire - more features cost more money. They also offer a free trial for 30 days (but it is wise to start the free trial at the begin of a month, as far as I recall).
The process of switching the email provider took me at least 6 months, where both the old and the new email adress have to exist simulatiously.
If you need to register quickly to an online service, i can recommend Temp-Mail org. Its free, but you need to have the tab opened for the registration process, as all data (including the free temporary email adress) will be deleted once the tab is closed. I used this service to register with my home instance, because back then I didn’t want to expose my real email adress.
