What are the third party SMTP servers?

Question

Email

They are making mysite.com and I need a server to send mail.
The easiest option, goole, but letters will come from @gmail.com but I still want @mysite.com
1.My hosting provides such a mail service, but I don't know what will happen if I want to change hosting?
2. I tried to find third-party servers in Google, so that I would pay a small amount of money there, (let's say 10 rubles for 100 letters), I registered it in the site settings and letters were sent from it, regardless of the hosting. But I didn't find

it. Can I make mail on hosting and be afraid to lose it with letters when changing hosting?
What third-party services exist for these purposes?
