To use a custom domain for your Sendspark videos, go to your workspace settings, scroll to Custom Domain, and enter the subdomain you want (e.g. videos.yourdomain.com). Then copy the Type, Host, and Value that Sendspark generates into your DNS provider’s records, return to Sendspark, and click Test Connection to verify.

​
Key takeaways

  • A custom domain lets you serve your video share pages and video request pages from your own subdomain, which helps videos get through firewalls and gives customers a consistent, white-label experience.
  • Set your subdomain in Workspace Settings under Custom Domain, then copy the generated Type, Host, and Value into your DNS provider’s records.
  • CNAME setup is hard to remove or update later, so be sure of your subdomain first; to swap domains, contact support. Subdomains are per-workspace, so each workspace needs its own unique subdomain.
  • DNS changes can take up to 24 hours to verify. In Cloudflare, set the Proxy Status to “DNS Only,” and after setup run your new URL through the Twitter Card Validator so previews show on Twitter.
If you want to share videos from your own domain URLs,you can connect your domain to Sendspark. This will give Sendspark permission to use your domain for your video share pages and video request pages. Connecting your domain will also help your videos get through firewalls and provide a more consistent, white-label experience for your customers.
Important Considerations:
  1. Once you set up CNAME, it will be hard to remove or update it. Please be absolutely sure of the subdomain you want to use before setting it up.
  2. If you have already set up a Custom Domain and you want to remove it so that you can add a new one, please contact support
  3. Subdomains are set on a per-workspace basis. If you are using multiple workspaces with Sendspark, you must add a new, unique subdomain for each workspace.
To start the domain connection process…
  • In your Sendspark account, go to workspace settings
  • Scroll to the bottom of the page, where it says Custom Domain

  • Locate the records for the domain you want to use
  • Go to DNS Settings

​

Add Sendspark to DNS Records Note: Use A record values from sendspark.com/settings/workspace. The values above are sample data.

​
Important Notes

  1. You might need to modify the value based on your DNS provider. For example, in GoDaddy and Cloudflare, you will only paste the subdomain (“video”) and not the root domain (“yoursite.com”).
  2. For Cloudflare, the Proxy Status should be**“DNS Only”** (so you will need to change the default, which is “Proxied”)
Proxies Here are the help documentation pages for common DNS providers:

​
Verify your Domain

  • Back in Sendspark, click Test Connection
Verify Custom Domain
  • If your domain is connected, you will see a green dot, and the word **Connected.**Way to go — you’re all set! 🥳
Custom Domain is Connected
  • If you’re still seeing Unverified, no worries! It can take up to 24 hours to update your DNS records. Please pour yourself some coffee, and try again in a bit. ☕️

​
Twitter Validation

Please note, after you set up your custom domain, you may have to run the new URL through Twitter Card Validator to get video previews to show up when you share Sendspark links on Twitter. Validate Twitter cards here.
