Auto-fill UTM parameters with live values
Insert dynamic placeholders like {{date}}, {{month}}, and {{campaign}} into your UTM links. Values resolve automatically at creation time, giving you unique, timestamped campaign URLs without manual entry.
Dynamic VariablesCampaigns often include dates, version numbers, or identifiers that change frequently. Manually updating these values for every link is tedious and error-prone.
Forgetting to update the date in campaign names (e.g., 'newsletter_jan' still used in March)
No way to auto-include timestamps or sequential IDs in UTM values
Dynamic ad platforms pass variables but UTM builders don't support them
Manual updates slow down high-volume link creation workflows
Variables like {{YYYY}}, {{MM}}, {{DD}} resolve to the current date automatically when the link is created.
No more stale campaign names. Dynamic variables ensure every link reflects the actual creation date.
Combine variables with bulk generation to produce hundreds of uniquely timestamped links at once.
Type {{date}}, {{month}}, or {{campaign}} in any UTM field. A preview shows the resolved value in real time.
When you generate the link, all variables are replaced with their actual values (e.g., {{YYYY-MM-DD}} becomes 2025-06-15).
Combine variables with templates to create self-updating presets that always produce fresh, unique URLs.
{{YYYY}}, {{MM}}, {{DD}}, {{YYYY-MM-DD}} resolve to the current date components.
{{timestamp}} and {{unix}} add unique time-based identifiers to prevent duplicate URLs.
Define your own variables like {{region}} or {{team}} and assign values at creation time.
See exactly how your variables will resolve before generating the final URL.
Embed variables inside templates for fully automated, always-fresh campaign links.
Variables expand individually for each row in bulk link creation.
