@pimoore They are available on both. It’s actually handled in the DNS settings, so more a domain management thing than an email provider one. In very basic terms, properly setting up things (DMARC, DKIM, BIMI) validates your email address reducing its chances of being marked as spam and increasing its visibility. For example, your company logo would show in the users inbox even if they don’t have you stored in their contacts. For now, it’s restricted to entities with trademarked logos. I believe it’s been proposed to open it up further though. Once I understood the specifics, the setup only took a few minutes.
