Privacy in email communication: we should use encryption by default
&gt; Therefore, in 2022 a daily email traffic of 333.2 billion emails is expected<p>I mean, sure, but let&#x27;s be honest, a big majority of that is going to be spam, the next step down from that are silly little things like email verifications, password resets, notifications, newsletter spam, and other similar crap. As a millennial who doesn&#x27;t touch emails for work or for personal reasons (because there is Slack, Signal or some other alternative to those two), I could very well be out of touch, but I&#x27;d be surprised if actual legitimate emails (both business and consumer) are more than 5% of that number.<p>I suppose 5% is still a big number, putting it at a comfortable ~16 billion emails.<p>Anyway, yes, we should be using encryption by default wherever possible, but honestly, encryption isn&#x27;t easy for the common folk, which is going to be the majority of those 333 billion. Heck, I migrated away from PM and I struggled with a lot of it. As someone who mostly lives in the CLI, GnuPG is not easy to use. Something like MailVelope makes it easier, but still not that easy.<p>Then there is the matter of administration. Your sysadmin, especially of the bigger orgs, do not want encryption on your emails. Especially when the business you&#x27;re in is regulated. Imagine being able to casually leak something without anyone knowing what&#x27;s in the content? I know regulation is usually not a good answer for why not, but within a business, yes, it totally is. As a customer of Big Bank Corp, I do not want employees to be able to mess with my data, money, or worse, the money of the bank so that it can fail and for my money (or the tax payer&#x27;s in case of govt protections) to be gone because everyone&#x27;s emails were encrypted.<p>The only viable solution here is something like ProtonMail, which actually makes it easier to use, at $&#x2F;£&#x2F;€ 5 per month, not many are able to afford to part with that. And no, their free tier is really not that great. But regardless, even PM doesn&#x27;t really help if a non PM user sends you an email.
