Buying and connect more than 10,000 domains to my proxied server

I’m Stephen, working for an email tracking tool. A few months ago, we introduced a feature that tracked links within emails. Unfortunately, we had to halt this feature after one of our users used it for phishing, leading to our tracking domain being blocklisted by Gmail, which caused emails containing our tracking links to land in spam.

We’re now planning to relaunch this feature with a new approach by creating a custom domain for each customer (e.g., client1-mailtrackerlink.com, client2-mailtrackerlink.com). Our tracking servers are hosted on Cloudflare and GCP, and we are seeking a solution to:

  • Purchase a custom domain for each customer.
  • Seamlessly integrate these domains with our proxied tunnel on Cloudflare.
  • Ensure each domain has a trusted SSL certificate.

Could you advise on how you can support us in achieving this? We’re particularly interested in automating these processes to streamline operations as we scale.

Before answering your questions, are you certain this is the approach you want to use?

If you buy client1-example.com through client10000-example.com today, there’s nothing stopping anyone from buying client10001-example.com tomorrow.

Also, this does not solve your problem with phishing but actually makes it worse. They are still your domains, and if multiple of them get reported for phishing, your entire account might get blocked by Cloudflare. This has happened before if you search on the forums and has the potential to cause huge downtime and costs to you.

The sane approach that basically everyone else is using is to have the customer use their own domain for tracking. Just ask the customer to create a CNAME record to target.example.com and you can use Cloudflare for SaaS to provide certificates automatically, with a single API call for every domain you add.

Thank you for your answer.
That’s not important if client10001-example.com is already taken, it was just a random example.

My customer can’t buy domain, they don’t have the knowledge to do that so add a CNAME to a domain looks impossible for them.

Any other solution like use Godaddy api to buy a domain and use it with a service like dnssimple?

How does url shortener like bitly managed this?

What do you think Google wil do when they see a thousand emails with different spamming domains – but all the emails originate from the same source?

And ask yourself – how does the rest of the industry handle this problem?
