About this tool
This page opens the UTM builder with the email convention prefilled: utm_source=newsletter and utm_medium=email. Add the campaign name for this send and the link is ready.
Email is where UTM tagging pays off fastest, because most mail clients otherwise report as "direct" traffic and vanish from attribution. Convention: utm_medium stays email everywhere, while utm_source distinguishes the list — newsletter, onboarding, digest, promo. Use utm_campaign for the specific send (spring-digest-04) and utm_content to separate the header button from the footer text link inside the same message.
Tag every link in the message, not just the hero button — footer clicks count too. The builder runs entirely in your browser, keeps any existing query parameters on your URL, and remembers your last five links locally so the next send reuses the same pattern.
Example. A landing URL plus source newsletter, medium email, and campaign spring is emitted with those three utm parameters percent-encoded.
Limit. The builder appends query parameters and does not shorten the link or check that the destination responds.
