Gmail adding a blue checkmark and you’ve already started making Twitter jokes at this point
Twitter’s adding a verified sender checkmark. Unfortunately it happens to be blue and look like Twitter’s, at least in the example image shown.
It appears the system uses DMARC and possibly BIMI to verify that the sender is an authorized sender and their logo is used in the preview.
It’s not clear if you have to have BIMI set up or if it’ll just blue checkmark DMARC, but if BIMI is involved so is the Trademark Office and that’s a whole ‘nother level of complexity.
The end result is emails that show with a blue checkmark should be from the real sender, or a phisher who’s managed to get into a compromised email account on the sender’s mail server.
Unlike Twitter’s crashing and burning status symbol this one’s useful.
Nothing you need to do unless you’re running your own website. OK, one thing to do and that’s start making checkmark jokes.
