Abstract: In embodiments of trusted email sender indicators, email messages are received for distribution, and validation techniques can be applied to determine whether a sender of an email message is trusted. If the sender of the email message is determined to be trusted, a trusted sender indicator can be associated with the email message for display with the email message. The trusted sender indicator indicates that the email message is from a trusted sender, such as when the trusted sender indicator is displayed along with the email message at a recipient client device.
