Built for marketers who care about clean data.

We started Bulk UTM Builder to solve a simple problem: spreadsheets are slow, error-prone, and don't provide real-time validation. Our mission is to provide the fastest, most secure way to manage tracking links at scale.

1

Paste URLs

Drop your raw target links into the builder.

2

Set Parameters

Apply global tags or override them per row.

3

Export CSV

Get your clean tracking data in seconds.

Privacy First Commitment

Unlike other UTM builders, we don't store your URLs, your campaign names, or your email. Everything happens entirely within your browser using JavaScript. When you close the tab, your data is gone.

  • No server-side processing
  • No cookies or tracking pixels
  • No account or login required

Why UTM Accuracy Matters

In 2026, data-driven marketing is more competitive than ever. A single typo in a UTM source-like "Google" vs "google"-can split your attribution data into two separate rows in GA4 or HubSpot, making it impossible to see the true ROI of your campaigns.

Our tool enforces best practices by automatically suggesting hyphens for spaces and flagging special characters that might break your links in certain apps or browsers.
