When you get a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC), you have two options for hosting your logo image (.svg) and your certificate (.pem): you can host them, or let DigiCert host them for you.
When you let DigiCert host your files, use these instructions to update your Domain Name System (DNS) record.
In CertCentral, in the left menu, go to Certificates > Orders.
On the Orders page, in the Order # column, select the order number for your Verified Mark Certificate or Common Mark Certificate.
On the Order # details page, on the Details tab, in the Logo and certificate settings section, select Display the URLs for hosted files.
Copy the URLs for your logo and certificate to use in your DNS record.
Repeat this process for each domain on the certificate.
Go to your DNS provider’s site and create a new TXT record.
In the Record type field (or equivalent), select TXT.
In the Host field, enter
default._bimi.[yourdomain.com], substituting your domain name for the bold text.In the Value field, enter
v=BIMI1; l=[URL of your logo]; a=[url of your certificate], substituting the logo and certificate URLs you copied from CertCentral.In the TTL field, enter 1 hour or 3600 seconds (depending what values your DNS provider accepts).
Save the new record to your domain.
Wait at least 48 hours for the new record to propagate through the DNS system.
