Add a custom domain
Add the hostname, create the DNS records shown, and issue links on your own name once verification passes.
Custom domains are a paid feature: Pro includes 1, Business up to 10.
Add the hostname
A subdomain such as go.yourcompany.com is the usual choice. Apex domains work too, with an A record instead of a CNAME.
Create the records we show you
The dashboard prints the exact name and value for your zone, with a copy control on each. Nothing has to be typed by hand.
Run the check
Verification resolves DNS from our side and tells you precisely what it saw — not just "failed". If your zone has a long TTL, wait it out and check again.
Issue links
Once the domain is verified, choose it in the create-link dialog. Links already issued on our domain keep working; the two live side by side.
RFC 1034 forbids a CNAME alongside other records at a zone apex, which is why an apex domain uses an A record. Some providers offer ALIAS or ANAME records that work around this; either is fine.
