One of the easiest things you can do to protect your email deliverability. Takes about ten minutes.
Every cold email you send with open or click tracking has a link embedded in it. That link tells you whether the email was opened and whether anyone clicked. Most people never think about where that link points. But email providers do, and it plays a real role in whether your email lands in the inbox.
This article explains what a tracking domain is, why using your own matters, and how to set one up in FoxReach in about ten minutes.
What is a tracking domain?
When you turn on open or click tracking in a campaign, FoxReach rewrites the links in your email. Instead of pointing directly to your website, they point to a tracking server first. The tracking server logs the open or click, then redirects the reader to the real destination.
The domain name of that tracking server is your tracking domain. It appears inside every tracked email you send.
By default, most cold email platforms use a shared tracking domain. That means every customer on the platform sends emails with links pointing to the same domain. It works, and nothing breaks. But there is a better way to do it.
Why your own tracking domain matters
Email providers like Gmail and Outlook check the reputation of every domain in your email, not just your sending domain. When your tracking links point to a shared domain used by thousands of other senders, your emails carry that shared reputation, good or bad.
If other senders on the same shared domain run into deliverability problems, the reputation of that domain drops. Your emails now contain a link to a domain with a weaker reputation, even though you did nothing wrong. This is one of the most overlooked reasons cold emails end up in spam when everything else looks fine.
A custom tracking domain solves this. Your tracking links point to your own domain, so your reputation is built entirely by your own sending behavior. Clean sends compound into a stronger domain over time, which is exactly how deliverability is designed to work.
What it does for you
Your reputation is yours alone
When your tracking links carry your own domain, your good sending behavior builds your own reputation. Other senders cannot affect it. Every clean campaign you run strengthens your domain, and that strength carries forward into the next campaign.
Better inbox placement
When your sending domain, your tracking domain, and your reply domain all belong to you, the email looks consistent and trustworthy to email providers. Mixed domains with different reputations raise flags. A custom tracking domain keeps everything aligned under your brand.
Your links look professional
A tracking link that reads track.yourcompany.com looks like it belongs in your email. Recipients who hover over links before clicking see a domain they recognize. That builds trust instead of raising questions.
Part of the full deliverability stack
FoxReach includes custom tracking domains alongside warmup, inbox rotation, email pacing, and real-time deliverability monitoring. All of it is included in your plan, with nothing gated behind a higher tier and no add-ons to buy. The whole deliverability stack works together, and a custom tracking domain is one piece of it.
When should you set this up?
Before you start sending, if you can. Set up your custom tracking domain at the same time you connect your email accounts and start warmup. That way every email you send from day one carries your own domain in its tracking links. Your reputation starts clean and stays clean.
If you are already sending, switching is still worth doing. Every email from that point forward will use your custom tracking domain. Campaigns that have already been sent are not affected.
Nothing breaks while you set this up. Until your custom domain is verified, tracking continues to work normally. There is no downtime and no risk to live campaigns.
How to set it up in FoxReach
The whole process takes about ten minutes. Most of that is waiting for DNS to update.
Step 1: Pick your subdomain
Choose a subdomain like track.yourcompany.com or email.yourcompany.com. Use a subdomain, not your root domain. Do not pick a subdomain that already hosts a website or other service.
Good choices: track., email., or go.
Avoid: your root domain (yourcompany.com) or any subdomain already in use. Also use a different subdomain than your sending domain to keep tracking and sending reputations separate.
Step 2: Add it in FoxReach
Open FoxReach and go to Settings (the gear icon, bottom left). Click the Integrations tab. Expand the Tracking Domain section. Type your subdomain in the box and click Add domain.
Step 3: Create the DNS record
After you add the domain, FoxReach shows you a CNAME record to create at your DNS provider. The record points your subdomain to the FoxReach tracking server.
Open your DNS manager (wherever your domain is hosted) and add a new CNAME record. In the "Name" or "Host" field, enter just the subdomain part (for example, track, not the full domain). In the "Value" or "Points to" field, paste the address FoxReach shows you.
If you use Cloudflare, make sure the proxy is set to DNS only (grey cloud, not orange). The orange proxy will interfere with the SSL certificate.
Step 4: Verify
Go back to FoxReach and click Verify. FoxReach checks the DNS record and issues an SSL certificate automatically. This usually takes a few minutes. The status moves from pending to verifying to active.
Once it says active, you are done. Every tracked email you send from that point forward will use your custom domain.
How long does it take?
| What you do | Time |
|---|---|
| Pick your subdomain | 1 minute |
| Add it in FoxReach | 1 minute |
| Create the DNS record | 2 to 5 minutes |
| Wait for verification and SSL | A few minutes |
| Total | About 10 minutes |
A few things to know
You still need to turn tracking on per campaign. The custom domain changes where tracking links point. It does not turn tracking on or off. You enable open and click tracking in each campaign's settings, the same way you always do.
Use a different subdomain than your sending domain. If you send from mail.yourcompany.com, do not use mail.yourcompany.com for tracking too. Keep them separate so a tracking issue cannot touch your sending reputation.
One domain per workspace is usually enough. If you run outbound for multiple clients using separate workspaces, consider a separate tracking subdomain for each client, so their reputations stay isolated from each other.
Set it up early. Every email sent before your custom domain is active carries a shared domain in its tracking links. Starting with your own domain from day one means your tracking reputation is clean from the first email.
