Can the URLs in a RCS message have a custom domain? Yes! Here's how you can go about it: **Step 1:** Create a custom domain that will exclusively be used to add links in your campaigns. **Step 2:** Add a CNAME entry for the custom domain and point it to *weurl.co* with a TTL (`time to live`) of 30 minutes in your DNS (Domain Name System) zone file. Doing so will ensure that your domain name is not replaced with *weurl.co* when the link is shortened. **Step 3:** Add the domain to your dashboard under *[Settings > Campaign Custom Domain](campaign-custom-domain)* And you're all set! *([Detailed read](campaign-custom-domain))* ### 2.
