I'm curious about the technical differences between email masking and just setting up a secondary email address that forwards to my main inbox. If I forward all the emails from this second address to my main one, isn't that the same as what email masking services do? It seems like people consider masking much more secure, but to me, it just sounds like creating another email that points to my real one. Am I overlooking something important regarding security and convenience?

Absolutely, the key difference lies in control and separation. With simple forwarding, you have one additional email still linked to your overall identity. Email masking lets you create unique emails for different sites, and if you encounter spam or a breach, you can instantly deactivate or generate a new masked address without any hassle.
When you create a secondary email that simply forwards to your main inbox, that email remains a fixed identity. It can still be compromised, sold, or traced back to you. The process of forwarding just passes along the emails; it doesn't provide any separation between accounts or minimize your exposure. If the forwarding inbox gets hacked, all accounts linked to it could be at risk. Email masking services, on the other hand, generate unique aliases for different accounts. So instead of just having one secondary email address for everything, you can have separate aliases for each service—like one for Netflix, one for forums, and another for shopping. This way, if one gets spammed or leaked, you can deactivate just that alias without affecting your other accounts. Plus, this method helps you track who might have shared your address without permission. The main difference is about control and reducing risk. Email masking helps you compartmentalize your online identities rather than just redirecting mail.
Email masking services offer the advantage of hiding the source of outbound emails. This means you can use different addresses for each site, making it safer. If any site begins to spam you or has a data breach that exposes user emails, you can easily disable that specific masked email without losing access to your main inbox.
