In my country, e-mail is now used purely as a sales tool. Notifications from government and schools are also delivered via SMS, and either WhatsApp or Telegram. So.. yeah, block everyone.

Turns out the second you do this you eliminate 100% of the spam in your life. Honestly, if I ever lived in North America again, I think I'd also just stop reading e-mail.

You're talking about personal email, they're talking about professional email.

Please do not assume that professional email is used differently. Plenty of companies here simply black hole inbound email unless it's from the same domain or known applications. Frankly, it's refreshing.
