If your organisation uses a proxy, firewall, VPN, or has other network security in place, it's possible that some pages of our product may be blocked or not function properly. This can mean that you may see a white page, blocked images or endless loading - instead of the content you're expecting.
Furthermore, emails you send to your company domain (whether test emails, or real sends) may not get through.
Fortunately, many IT teams that have implemented network security also have provisions for whitelisting. If you’ve run into issues related to network security restrictions, then you'll need to work with your IT and/or security team to whitelist our platform. Whitelisting requirements for our system are fairly straight forward and you can easily test on your end whether or not you need to get your IT team involved.

Hi, we use Vision6 to create and send email campaigns to our customers and recently, we've been having trouble accessing some of the content on their service.
It looks as though it could be being blocked by our own security infrastructure and the provider has suggested that we get in touch with IT to have their domain whitelisted.
Specifically, the domain to whitelist is:
This is the CDN address where the files for their product is hosted. If you need any further information from the email provider, let me know and I can put you in touch with them directly.
