Try setting up a SMTP server for youself. You'll instantly get added to a spam blacklist.

To be clear, you don't need to run email servers yourself just to use email which is an open protocol.

There are plenty of providers, even if you steer clear (as you should) of the big monopolies of gmail and microsoft.

But to address the specific comment,

I do and no. I run my own email infrastructure, including delivery. Works just fine.
