All those free and popular email services like Gmail aren’t as private as you think. The companies behind them have access to your email account, so they can technically view every email you have ever sent and received. While we have to trust that large, reputable companies follow their own privacy rules and don’t do that, they are definitely scanning all your emails automatically to provide popular features like Smart Reply and automatic sorting. Some even use that data to train their AI models, and all of them are required to hand over data to the government when asked.
Your email should be your business. Period. And that’s where secure email services come in. These differ from those offered by Big Tech because they use end-to-end encryption. They are completely secure, so the companies that own them can’t see your emails even if they wanted to.
