Set Up Your Tracking Domains

Why You Need a Custom Domain

FunnelFlux requires you to bring your own custom tracking domain. This gives you full control over your tracking links -- they look professional, build trust with your audience, and improve deliverability when sharing URLs across ad platforms and email.

You can use a root domain like domain.com or a subdomain like track.domain.com. A common pattern is to point your root domain at a landing page system and use a subdomain for tracking.

Your tracking domain does not need to be related to your page domains. However, using a subdomain of your page domain is beneficial -- browsers and extensions are less likely to block cookies and JavaScript when they come from the same parent domain.

Before You Start: Use Cloudflare for DNS

While not strictly required, we strongly recommend managing your DNS through Cloudflare. It is the fastest and most fully-featured free DNS provider available, and it simplifies several aspects of domain setup with FunnelFlux.

If you do not currently use Cloudflare, create a free account and add your domain. You will need to update your domain registrar to use the nameservers Cloudflare provides. Here are instructions for common registrars:

• Namecheap -- select the Custom DNS option and enter your Cloudflare nameservers
• GoDaddy -- use "Enter my own nameservers (advanced)" and enter your Cloudflare nameservers

Step 1: Add Your Domain in FunnelFlux

1. Go to the Domains page in FunnelFlux.
2. Click Add Domain.
3. Enter your full domain or subdomain -- just domain.com or track.domain.com. Do not include https:// or any path.

This registers the domain on FunnelFlux's side. Next, you need to configure DNS records so the domain actually points to FunnelFlux and SSL can be provisioned.

Step 2: Add a CNAME Record

In your DNS provider, add a CNAME record pointing to:

edge.funnelflux.pro

This is the same target for every domain you add. The CNAME target is shown above the domain table on the Custom Tracking Domains page.

To see the exact record FunnelFlux expects, click the DNS records icon in the DNS column -- that opens the Domain Settings panel:

The CNAME Record card shows the record name (your hostname) and value (edge.funnelflux.pro):

If you are using Cloudflare, you can leave the record in orange cloud (proxy) mode.

You can add this CNAME record before or after registering the domain in FunnelFlux -- order does not matter.

Step 3: Add a TXT Record for SSL Verification

FunnelFlux provisions SSL certificates for your domain through Cloudflare. To verify ownership, you may need to add a TXT record.

1. Click the DNS records icon for your domain to open Domain Settings.
2. Check the SSL Certificate Validation Record card. If SSL validation is pending, it shows a TXT record name and value to add at your DNS provider. If nothing is pending, you will only see a status line -- no extra TXT is required.
3. There is also an Optional | Hostname Pre-validation Record card. That supplies a _cf-custom-hostname TXT record you can add ahead of time if you want Cloudflare to pre-validate the hostname.
4. If a TXT name and value are shown, add them as a TXT record at your DNS provider and save. Validation may take up to 10 minutes.

To refresh status, click the DNS records icon again -- Domain Settings pulls the latest status from Cloudflare each time.

Note: If you already had an existing Cloudflare record in orange cloud (proxy) mode and are updating it to point to FunnelFlux, you may not need this TXT record at all. Cloudflare may have already verified your domain. It does not hurt to add the TXT record regardless, but if verification seems stuck, just make sure the CNAME is in place -- the domain should transition automatically.

Step 4: Verify Your Domain Is Working

On the Domains page, each domain has a status label. Refresh the page to see updates -- the status checks whether your domain is correctly pointing to FunnelFlux with SSL working.

You can also open Domain Settings and use Overall Domain Health -- it links to our debug page and has a Check now button that tests the FunnelFlux endpoint.

Once the status shows as active, your domain is ready to use in tracking links.
