Email has become so ubiquitous that email addresses are now synonymous with a user's identities. More and more services and applications require users to share their email address alongside their other personal data. This tight coupling of an email address with personal identity carries significant privacy and security implications. If these are left unchecked, they expose users to significant threats such as identity theft, social engineering, account takeovers, doxing, and more. The Sudo Platform offers the following capabilities for enabling users to operate more security, privately and in control of their email. ## Key Features


Email Addresses	Give your users one or more of fully featured email accounts for your use case. Email Addresses include all the send, receive, folder, spam capabilities and more that you expect from an email service. This is the ultimate in private email solutions, your users' inbox is encrypted, only accessible to them and works in both E2EE or public email use cases.
Email Masks	For your users who prefer to keep their existing email provider, while obfuscating their real email address, the Sudo Platform offers Email Masks. Email Masks offer an additional level of privacy for your real email address when interacting with sites, apps or interactions.
