Use your own domain for your help center
By default your help center lives at yourslug.acornreply.com/knowledge. On a paid plan, you can serve it from your own domain instead — like help.yourcompany.com — so it feels like a seamless part of your site. Set it up under Settings → Knowledge → Custom domain (admins only).
Add your domain
Enter the hostname you want to use, such as help.yourcompany.com. It should be a subdomain of a domain you control — a bare hostname with no https://, port, or path.
When you add it, AcornReply gives you the DNS records to create at your domain provider.
Add the DNS records
You'll add two kinds of record at your DNS provider:
- TXT records — used to verify you own the domain and to issue an HTTPS certificate for it.
- A CNAME —
help.yourcompany.compointing todomains.acornreply.com.
The order matters, and it's designed so nothing breaks:
- Add the TXT records first and let verification complete. Your existing help center keeps working the whole time.
- Then add the CNAME. That's the cutover moment — once it's live, traffic to your custom domain serves your help center.
Watch the status
The settings page shows where things stand — pending DNS → verifying → active — and a Check status button re-checks after you've added records. DNS changes can take a little while to propagate, so if it's not active immediately, give it time and check again.
After it's live
Once your custom domain is active, your help center is served at https://help.yourcompany.com/knowledge, and the old yourslug.acornreply.com address automatically redirects there — so any links you'd already shared keep working.
Custom domains are a paid feature. If you downgrade later, you can still see and remove a configured domain, but adding a new one requires an eligible plan.
