I'm trying to register for a website without exposing my main personal email address. Temporary and disposable email services are blocked, and the site says the provider isn't allowed. I'm not trying to bypass verification or do anything suspicious—I simply may use the site once and don't want it connected to my primary inbox. What alternatives are generally accepted, such as a secondary mailbox, email aliases, masked forwarding addresses, or a custom-domain address?

The simplest option is to create a separate mailbox with an established provider and use it only for signups like this. Since it’s a normal, long-standing email service rather than a disposable domain, it’s much more likely to be accepted. You can check it occasionally or set up forwarding to your main inbox.
If none of those work, the practical choices are using an old secondary account from a mainstream provider, asking the company’s support team whether they can approve the address, or choosing a competing service without the restriction. Avoid cycling through disposable domains, since the block is usually intentional.
A masked email service or Apple’s private forwarding addresses can hide your real address while still giving the website a unique, functioning mailbox. These are different from temporary inboxes because messages are forwarded and the address can usually be disabled later.
Email aliases are useful if your provider supports them. Plus addressing, such as [email protected], can help identify who shared your address and makes filtering easier, but some websites reject the plus sign or treat every variation as the same account.
