BIMI, or Brand Indicators for Message Identification, is a cutting-edge email authentication protocol. Simply put, BIMI allows you to show off a trusted sender logo with all your emails in your recipient’s inbox. Without BIMI, all you can see are just uniform letters in colored circles, which is likely to be less trusted or opened. The primal purpose of BIMI is to verify that you are who you say you are—not a scammer or spammer.
