How Certified Email Works

 

Accreditation

CertifiedEmail is trusted-class email: to qualify for it, a sender must have among the lowest complaint rates. Accreditation takes about one week and costs a one-time fee of $399. Find out more.

1. CertifiedEmail Imprinting

CertifiedEmail works with how you send email today - your existing email service provider (ESP), or your existing infrastructure if you maintain your own system. CertifiedEmail Imprinting software - located at your ESP or within your own system - imprints email with a unique, cryptographically secure token.

2. ISP Routing

Participating ISPs detect the token on incoming CertifiedEmail messages and automatically process CertifiedEmail differently from regular email, bypassing content and volume filters and delivering it directly to the recipient's inbox. Links and images are rendered on default.

3. Inbox Presentation

CertifiedEmail messages are displayed with a special blue ribbon envelope icon, letting consumers know that the email message is authentic and comes from a verified sender. They see this at the inbox level view, as well as when they open the message.

4. Delivery Confirmation

Since CertifiedEmail messages are all imprinted with unique tokens, and ISPs validate each token when these messages are delivered, senders obtain accurate delivery confirmation at the message level.

5. Regular Email

Regular email must pass through ISP Volume and Content Filters. These emails may be deleted, have their images and links blocked, or go into the junk email folder.
