How it works

Existing query parameters on the destination are kept, and UTM values are percent-encoded so spaces and ampersands survive.
Be consistent with casing — Email and email show up as two different sources in most analytics reports.
utm_source and utm_medium are the only parameters you really need; the rest are optional refinements.
