To send email from a secondary domain (e.g., mail.cocoonmail.so) with a sending avatar:
Log into your Google Admin console with an administrator account
Go to “Manage domains” in the dropdown menu
Click “Add a domain” and enter the domain name
Select “secondary domain” or “User alias domain” as appropriate
Add and start verification
Once verified, the secondary domain will use the same sending avatar as the primary domain.Note that avatars are only visible within the same email client. To display your avatar across all clients, create accounts and upload avatars in each one’s settings.Alternatively, consider using BIMI (Brand Indicators for Message Identification), a new email standard for displaying authenticated logos. BIMI requires some setup and legal work but provides an added layer of trust.
