APPLE’S MAIL APP is often overlooked in favor of alternative email clients that appear to offer more in the way of features. However, it’s a very capable and easy–to–use tool and offers many advantages, particularly if you have multiple Apple devices and synchronize them using iCloud. What’s more, it’s had a couple of decent upgrades in recent versions of macOS, many of them focused on privacy. Sign in with Apple enables you to sign up to an email newsletter or enter a competition using a random email address that is forwarded to your iCloud email account. That prevents the sender from knowing your real address. And in Monterey, you can generate a random email address using Hide My Email.
Mail can also prevent senders finding out whether you have opened an email, if you select the option to block all remote content from loading. In Monterey, this is improved so that content is routed via a relay and you can load images while still preventing the sender from tracking whether you opened the message.
