What is UTM Bulk Builder?
Campaign calendars need dozens of tagged URLs without hand-building each one. ToolYour UTM Bulk Builder takes a shared baseUrl, optional shared utm_* defaults, and rows[] (or csv/text lines) to emit one URL per row. Rows missing core UTMs return per-row errors. Not a spreadsheet product or Ads upload API. Same route via REST and MCP (POST /api/v1/marketing-apis/utm-bulk-builder).
What are common questions about UTM Bulk Builder?
How do I pass many campaigns?
Send rows[] objects with utm fields, or paste csv/text lines (optional header with utm_* columns).
What if a row fails?
That row returns an error for missing source/medium/campaign; other rows still build.
Is there a row limit?
The tool is built for campaign-calendar batches (tens of rows); very large lists are better split into a few calls. Each row is validated independently regardless of batch size.
What are the key features of UTM Bulk Builder?
Shared defaults + per-row overrides
Set medium once; vary campaign/content per line.
CSV-friendly input
Paste lines for quick calendar exports.
How do you use UTM Bulk Builder?
Set base URL and shared UTMs
Source/medium often stay constant.
Paste campaign rows
Export the result URLs into your tracker or ESP.
Why this tool exists
A campaign calendar with dozens of placements needs dozens of correctly tagged URLs, and building each one by hand in UTM Builder doesn't scale past a handful of rows. UTM Bulk Builder exists to turn a shared base URL plus a list of campaign rows into a full batch of tagged links in one pass.
Problems it solves
Manually repeating the same source/medium across 30 rows in a spreadsheet, then hand-building each URL, is slow and invites copy-paste drift — one row keeps an old campaign name, another has a typo in the medium. Per-row validation catches missing core UTMs before the batch ships instead of after.
Common use cases
- Agency campaign calendar: generating a full month of tagged links for a client's content calendar from one CSV export.
- In-house affiliate/partner program: building unique tracked links per partner from a shared base URL and partner list.
- Pre-launch: producing every campaign's tagged link at once before a multi-channel product launch.
- Agent/MCP: an agent building a batch of campaign URLs as one step in a larger launch playbook.
Honest scope
This builds URLs from rows you provide — it is not a spreadsheet product and not an Ads upload API; you still paste the results into your tracker, ESP, or ad platform. Rows missing core UTMs return a per-row error rather than silently building a broken link.
