Quickly create Fastmail Masked Email addresses. It includes a client package for use in other projects in addition to the CLI.

What is Fastmail Masked Email ?

A Masked Email address is a unique, automatically generated email address that can be used in place of your real email address.

Masked Email addresses are especially useful when you need to sign up with new services online. Instead of sharing your real email address, keep it private and protect yourself from data breaches and spam by creating a new Masked Email for every service.

If a Masked Email address starts receiving unwanted mail, you can simply disable that address. Masked Email addresses also make it easy to identify which service shared or leaked the address.
