I have a couple of webmail accounts. There’s the one I use for Important Stuff, like applying for visas, clawing back erroneously paid tax, and saving lives – and the one I use for everything else.
The reason I use two accounts is because everybody wants to spam me. Spam is just another form of currency. If I want to purchase item X or service Y from you, it costs me Z. But that’s not all it costs me. It costs me regular weekly emails from you and all your partners, and all the idiot companies you’ve passed my email address to.
I don’t want these emails. I don’t like them, I don’t read them. This crap outnumbers the number of emails that mean anything. What makes you think I read them, anyway?
