An email service that displays the logo of the sender or brand for authenticated emails that arrive in consumer inboxes is scheduled for launch Tuesday, writes DM News. Email identification firm Iconix is working with business-to-consumer marketers on a pilot of the Trumark technology, which is similar to security certificates used on many websites to show consumers that the email is from a trusted source and not, say, a phisher.

"Part of what we're bringing back is brand control, to the ones that have been victims of phishing," Wilbur said. In the service's pay-for-performance pricing model, the sender pays a fraction of a penny each time a logo is displayed in a consumer's inbox.
