How to use this tool
Choose the relevant mode, enter Base URL and complete the labelled fields. Use Calculate to review your result.
Worked example
Base URL = https://example.com/?a=1, Campaign source = email, Campaign medium = digest, Campaign name = launch.
Final URL = https://example.com/?a=1&utm_source=email&utm_medium=digest&utm_campaign=launch.
These example values are illustrative.
Interpreting the result
Open the generated link in a private staging test only after checking the destination and campaign taxonomy. Keep spelling and capitalization consistent across channels.

What happens to existing tags and fragments?
The five campaign keys are replaced. Other query parameters and the fragment remain in the resulting URL.
