# Email Masks

**Email Masks** are a light weight alternative to [Email Addresses](/guides/email/email-addresses.md) for your use cases where email address obfuscation is necessary but you do not want to manage email message data.

Email Masks act as a relay mechanism that forward messages to and from your users real email address via an intermediary email address (the "mask address").

Email Masks can be used in multiple use cases including:

* Building consumer email masking solutions for general privacy enhancement.
* Protecting users real email addresses from workers in:
  * "gig economy" type software platforms.
  * Booking confirmation platforms, etc.
