How to Add and Authenticate a CDN Domain


Adding and authenticating your own CDN domains means that images hosted in your emails will use your own domain rather than one of our shared domains.

This can allow for better inboxing if one of our shared domains rarely gets blocked due to another customer.

Here's how to add your own CDN Domain.

Step 1: Before you begin, you must make sure you are logged in to the MAILVIO control panel.

Step 2: Click your name at the top right of the control panel, and then click Company Profile.


Step 3: Click the "My Domains" tab towards the top of the screen.


Step 4: Now click "Add & Verify a New Tracking Domain"


Step 5: A drawer will slide onto the screen asking you for the domain you would like to use for your CDN domain. Usually, people would use a subdomain here, so for example if your domain is example.com you might use cdn.example.com for the CDN domain.

Enter your chosen CDN domain or subdomain in the box.

The drawer also details the CNAME record you need to add to your DNS records. 


Step 6: Now you have created the record and entered your domain or subdomain click the "Continue" button back on our Control Panel.

Once the DNS changes reach us the drawer will close and your domain is ready to use.
Please note: It can take up to 48 hours for the domain changes to reach us, however ordinarily changes should reach us within 1 hour.

Step 7 (Paid subscribers Only): If you have a paid subscription you will notice the domain now says "SSL Pending". As part of our service to paid subscribers, we automatically generate SSL records for all domains added.

This process can take up to 1 hour so please wait until this SSL record changes to completed before sending.
