Setting up a custom domain (share.yourcompany.com)

Send links and signature envelopes from your own domain. Wildcard SSL handled.

Before you start

You'll need DNS access for the domain you want to use, plus Owner or Admin role in your Dataroom workspace.

Step-by-step

Go to Settings → Branding → Custom domain.
Enter the subdomain you want (e.g. share.acme.com) and click Add.
Copy the CNAME target Dataroom shows you.
In your DNS provider, create a CNAME record from share.acme.com pointing to the Dataroom target.
Wait 2–10 minutes for propagation. Dataroom auto-detects, provisions SSL via Let's Encrypt, and flips the domain to Live.

Per-client subdomains? Add a wildcard CNAME (*.share.acme.com) pointing to our wildcard target. You can then provision per-client subdomains from the API.

Branded transactional emails

Configure DKIM and SPF for send@yourdomain.com in Settings → Branding → Email. Once verified, all transactional emails (invitations, completion receipts, reminders) ship from your address.
