Using your own domain for CamBuildr makes all of your pages look more professional. CamBuildr supports custom domains at three different levels, depending on what you want to brand:
Your whole organization — one subdomain that hosts all of your CamBuildr pages.
A single campaign — a separate domain or path prefix for one specific campaign.
A single landing page — a dedicated domain pointing to just one page (set up by our team).
You can also combine these — for example, an organization-wide subdomain plus a separate domain for one high-profile campaign.
Option 1: A subdomain for your whole organization
This is the most common setup. All of your CamBuildr pages — landing pages, signup forms, and email links — will be served from your subdomain.
Your domain is in use elsewhere (home page, etc.), and you still want to use it for CamBuildr? Choose a subdomain of your domain. If your domain is domain.com, possible subdomains are participate.domain.com or secure.domain.com. You can get creative here.
To set it up:
In CamBuildr, click Organization in the bottom left-hand corner.
Enter your desired subdomain in the Custom Domain field.
You will be shown a CNAME record to set in your domain configuration tool. For an apex domain (one without a
www.or other prefix), CamBuildr will also show an A record as a fallback.After you've set the DNS record, CamBuildr verifies it automatically. While we wait, the setting shows a Pending validation status.
Once verification succeeds, you will receive an email confirming that your custom domain is active.
Option 2: A separate domain or path for a single campaign
Sometimes you want a campaign to stand on its own — a dedicated brand or a clean URL just for that initiative. Each CamBuildr campaign can have its own routing, independent of the organization-wide custom domain.
There are two modes:
Domain mode: attach a full domain or subdomain to the campaign (for example
vote2026.domain.comorvote2026.com). All pages in that campaign will be served from that domain.Path prefix mode: keep using your main domain but add a campaign-specific path, for example
participate.domain.com/vote2026. Useful when you don't want to manage a separate domain.
To set it up:
Open the campaign you want to brand and click Edit domain.
Choose Domain or Path prefix mode and enter your value.
For Domain mode, set the CNAME (or A record for an apex domain) shown by CamBuildr. The campaign will be marked Pending validation until DNS resolves; you'll receive an email once it's active.
Optionally pick a home landing page — this is what visitors will see when they go to the root of your campaign URL.
If you are moving from a previous campaign domain, CamBuildr can automatically 301-redirect the old domain to the new one, so your existing links keep working.
Each campaign is independent — having a campaign domain does not require or change your organization-wide custom domain.
Option 3: A dedicated domain for a single landing page
If you want a domain to point to one specific landing page — for example a vanity URL for a petition or a one-page event site — please reach out to us. Our team can configure a dedicated domain that renders just that page.
This is also the right option if you want to use a domain solely for CamBuildr at the page level rather than at the organization or campaign level.
