We also shouldn’t have to have so much spam, but alas people are crappy. So the common routes get targeted. Welcome to the modern internet.

Do you have a better solution?

You can complain on the forums about how unfair life is, how incompetent companies are, fight every provider to prove your reputation until cows come home,… Or you can pay someone to handle that for you. It’s a no-brainer. The whole discussion is moot.

You pay your plumber to plumb, your builder to build, and email delivery company to deliver your emails. Trying to DYI everything is a waste of everyone’s time.
