What Is BIMI SVG CDN Hosting

What Is BIMI SVG CDN Hosting 

Overview 

BIMI SVG CDN hosting means SSL.com stores your BIMI logo at a stable, public HTTPS URL — https://bimi.ssl.com/mc-{ref}.svg — as soon as your Verified Mark Certificate (VMC) or Common Mark Certificate (CMC) is issued. You point your BIMI DNS record at that URL, so you no longer need to host the logo file on your own web server. 

Key takeaway: every VMC and CMC from SSL.com includes an SSL.com-hosted public URL for your BIMI logo, at no extra cost.  Why it matters. Email providers such as Gmail and Yahoo display your logo by downloading it from the HTTPS address in your BIMI DNS record. That file has to stay online, stay unchanged, and match the logo inside your certificate. SSL.com hosting takes care of all three.  What you get: 

• A permanent logo URL on bimi.ssl.com, delivered over HTTPS from a global content delivery network (CDN) 

• A hosted copy of your Mark Certificate (PEM file) for the BIMI a= tag 

• A hosted logo that exactly matches the logo embedded in your certificate 

• Your URLs and a ready-to-publish BIMI DNS record in your SSL.com account and issuance email 

• The same URLs after you renew or rekey with the same logo, so your DNS record does not need updating 

Who it’s for: customers with a Verified Mark Certificate (VMC), Common Mark Certificate (CMC), or Government Mark Certificate (GMC). 

How BIMI logo hosting works 

BIMI needs two files that anyone can download over HTTPS: your logo (named in the l= tag of your BIMI record) and your Mark Certificate (named in the a= tag). SSL.com hosts both under one reference ID that starts with mc-. 

File	URL	BIMI tag
Logo	https://bimi.ssl.com/mc-{ref}.svg	l=
Mark Certificate	https://bimi.ssl.com/mc-{ref}.pem	a=

From order to hosted logo: 

1. You upload your logo in SVG Tiny Portable/Secure (SVG Tiny PS) format with your VMC or CMC order. 
2. SSL.com validates your organization and mark, then embeds your logo in the certificate. 
3. When the certificate is issued, SSL.com publishes your logo and certificate at bimi.ssl.com. 
4. Your hosted URLs and BIMI DNS record appear in your SSL.com account and in your issuance email. 
5. You publish the BIMI record in your domain’s DNS, and supporting inboxes start showing your logo. 

Example BIMI record:  default._bimi.example.com.  TXT  “v=BIMI1; l=https://bimi.ssl.com/mc-a1b2c3d4.svg; a=https://bimi.ssl.com/mc-a1b2c3d4.pem”  Built to pass BIMI checks. The hosted logo is an exact copy of the logo inside your certificate, and the hosted certificate file includes the full chain that email providers need to confirm it was issued by a trusted authority. 

Requirements 

SSL.com hosts the logo for you, but the logo itself must still meet BIMI’s file rules before your certificate can be issued. See VMC Logo File Requirements for full details.  What the hosting service provides:

FAQ 

What is BIMI SVG CDN hosting? A public HTTPS URL on bimi.ssl.com, created when your Mark Certificate is issued, that serves your BIMI logo and certificate for use in your BIMI DNS record.  Does it cost extra? No. Hosting is included with your VMC, CMC, or GMC.  Does my URL change when I renew or rekey? Not if you keep the same logo. Your URLs stay the same and automatically serve the logo and certificate from your new certificate, so you don’t need to change your DNS record. If you upload a new logo during a rekey or renewal, you get new URLs and need to update your BIMI DNS record.  I bought my Mark Certificate before hosting was available. Do I have a hosted URL? Open the certificate in your SSL.com account to find its hosted URL. If none is shown, contact SSL.com support.  Can I still host the logo myself? Yes. BIMI only requires a public HTTPS URL. If you host it yourself, your file must exactly match the logo embedded in your certificate, and you are responsible for keeping it online.  Why is the <title> in my hosted logo different from my upload? SSL.com sets the logo’s <title> to the validated organization name in your certificate during issuance. The hosted logo and the logo in your certificate are identical.  Is the hosted URL based on my domain name? No. It uses a unique reference ID that starts with mc-. Always copy it from your SSL.com account.  Do Government Mark Certificates (GMC) include hosting? Yes. GMCs get the same hosted logo URL and BIMI DNS record as VMCs and CMCs.  Which email clients show my logo? Gmail, Yahoo Mail, and Apple Mail display BIMI logos. Apple Mail shows logos from VMCs only. Gmail adds a blue verified checkmark for VMCs and GMCs. Outlook does not support BIMI.
