> Ability to use multiple aliases. I want to have site_name@rolisz.ro, besides the main address I will give out, but still have everything come in to my main inbox.

It's not an alias, but you can effectively get this for free with any mail provider by using a plus sign (+). For a really extreme (and awesome) example, see:

He suggests using emails like: aorth+news.ycombinator.com+2020-04-12@example.com. The benefits are that you get a lightweight alias that you can filter on, but you also get a canary that tells you which site sold your email address when you start getting spam to it! :)
