Feature Request: Support dont-track attribute to exclude specific links from tracking

[honzavalusek]

Hi,

Thanks for this package — it's been very helpful.

I’d like to request a feature that allows users to exclude specific links from being tracked.

---

🧩 Proposed Feature

Add support for a custom HTML attribute like data-dont-track (or similar), which users can apply to <a> tags to indicate that those links should not be rewritten or tracked by the package even if the track-links config option is set to true.

Example Usage:

<a href="https://example.com" data-dont-track>Untracked Link</a>

In this example, the link to https://example.com would be rendered in the email without any tracking applied, even if other links in the same message are being tracked.

---

💡 Use Case

There are scenarios where tracking all links isn't desirable — for example:

• Links to unsubscribe pages
• Privacy-sensitive external links
• Internal links used purely for accessibility or compliance

Having this option would give users finer control over what gets tracked.

⚙️ Implementation Idea

During the HTML parsing phase, the logic could skip adding tracking parameters to links that have the data-dont-track attribute (or similar).
The attribute could then be removed from the final rendered HTML to keep things clean.

🤝 Contribution

I'd be happy to implement this feature and open a PR if you're open to the idea.

Thanks for considering!

Let me know if you want to change the attribute name (data-dont-track), or if you’d like a draft implementation outline to help get started.

I think it's a reasonable thing to add - feel free to create a PR. Be sure to have appropriate test cases with it. Thanks!
