When trying to protect your primary inbox from spam, you generally have two useful tools: email aliases and disposable temporary emails. They sound similar, but they solve different problems.
How Email Aliases Work
An email alias is usually a forwarding address. A service creates an address for a website, and messages sent there are forwarded to your real inbox. If the website starts spamming you, you can disable that alias.
Aliases are ideal for long-term relationships. Use them for stores, forums, or SaaS tools that you plan to keep using because you may still need password reset links later.
The Mechanics of Disposable Emails
Disposable emails, like SableMail inboxes, are public and temporary. There is no forwarding and no permanent storage. You open a web page, check the address, receive a message, and move on.
They are useful for one-off interactions, free downloads, demos, and testing. Because they are public and temporary, they should not be used for private or long-term accounts.
Choosing the Right Tool
Ask yourself whether you will need to access the website again after today. If yes, use an alias. If no, a disposable temporary inbox may be the faster option.
