I can setup email on my own domain, but I don't want to. It isn't worth my time or money. This doesn't mean that I can't follow tunnel broker instructions.

I wasn't aware that there are only two options: completely self-hosted or Gmail.

I bet if someone made something in between, it might become at least a little popular.

Before Gmail we had Hotmail.

Still works by the way!

As the kids once said: No duh.

Gmail rejects mailing list messages that every other email provider accepts. It is impossible to get a human at Google to look at these issues. That's kinda the worst of all worlds. At least other email providing companies have support teams that can be talked to when things go off the rails.
