What is Trusted Delivery?

Trusted Delivery is a patent pending authentication system for email. It prevents email spoofing by ensuring that the email was sent from the person identified as the sender.

This "proof of sender" technology can be used in many different industries where companies rely on email communication to their customers.

How does it work?

When a person uses Trusted Delivery and sends an email message using Webmail or an email client such as Outlook, the following actions occur:

  1. A hash of the sender, receiver and other data is taken.
  2. The hash is stored in a database.
  3. Once the email arrives at its destination, the mail server (or email client plug-in) can lookup the hash and verify the sender. This is done by a DNS query to the Trusted Delivery DNS.

These actions are done "behind the scenes" and are invisible to the user.

How does Bluebottle use Trusted Delivery?

All Bluebottle users have Trusted Delivery tags added to their email headers. If a Bluebottle user sends an email message to a third-party who uses Trusted Delivery then the system can identify the email as coming from them, and not someone else.

Bluebottle users can view their Trusted Delivery statistics within the webmail interface. This tells them the number of Trusted, Not Trusted and Not Validated emails they received within a 24 hour period.
