What is the benefit of BIMI for Mailbox Providers?
BIMI promotes authentication, which is instrumental in protecting against some forms of abuse. BIMI’s goal is to promote message authentication and to allow brands to control the display of their logos in email they send. This solution aims to simplify the need for mailbox providers to support proprietary logo management systems.
Why don’t I create my own system to handle logos?
BIMI allows mailbox providers to leverage a system that is meant to scale and allow providers to obtain logos from locations specified by the brands. Maintaining a proprietary system can be difficult, time consuming, and add additional support costs. BIMI provides a standard for mailbox providers to display the same logos across platforms. Additionally, it provides verification that logos are approved by a 3rd party.
Why should I display logos?
Displaying logos can allow mailbox providers to create a richer, more engaging experience that connects brands and their consumers in a more meaningful way.
Is the MBP required to show a logo for a domain that employs BIMI?
No, a mailbox provider can make local determinations for individual domains. There is a draft BCP (https://tools.ietf.org/html/draft-brotman-ietf-bimi-guidance-01) for MBPs that discusses this in more detail.
