The easiest way to get a branded link shortener without touching your website is a subdomain, for example go.yourbrand.com or link.yourbrand.com. Your website on yourbrand.com keeps working as before. Custom domains are available on paid plans (Pro and higher).
1. Add the subdomain in Capsulink
- Log in to Capsulink and open Settings → Custom domains.
- Enter the full subdomain (for example go.yourbrand.com).
- Optionally, enter the main redirect URL and the Not Found (404) redirect URL.
2. Add a CNAME record
In the DNS settings of your domain (registrar, hosting or Cloudflare) add:
- Type: CNAME
- Host / Name: your subdomain, for example go (some providers want the full name go.yourbrand.com)
- Points to / Value: cname.capsulink.com (if your provider doesn't accept the dot at the end, leave it out)
If there is already a record for this subdomain, edit it instead of adding a second one. Other records (your website, MX for email) stay unchanged.
A CNAME is recommended for subdomains. An A record to 91.241.66.74 also works, but with a CNAME any future change of our server addresses is applied automatically.
Using Cloudflare? Set the record to DNS only (grey cloud), not Proxied.
Check the status in Capsulink
Open Settings → Custom domains. While Capsulink is waiting for the DNS record, the domain shows Verifying. As soon as the record is found, the status changes to Verified and you receive an email "Domain is verified". You can then pick the domain when you create short links.
DNS changes usually take 10–30 minutes and sometimes up to 24 hours. You don't have to wait for our automatic check: click Check DNS now next to the domain to check it right away.
If the status is Verification Failed, Capsulink shows what it found instead (for example, another IP address). Fix the record and click Check DNS now again. There is no need to delete and re-add the domain.
The SSL certificate (https) for your domain is issued automatically after verification, no extra setup is needed.
