# Sender Authorization

Sender authorization is a functionality that allows you to authorize a domain that will be used to send messages through EmailLabs. It protects your account from messages sent by unauthorized third-party senders. Moreover, your emails are being signed with a DKIM key. In EmailLabs, you can authorize the whole domain.
