Your inquiry is insightful. UTM parameters are snippets of code appended to the end of URLs in your email links. They play a crucial role in helping analytics tools like Google Analytics trace the origins of your website traffic, providing valuable insights into the performance of your email campaigns.
There are five standard UTM parameters, though not all are necessary for every email link.
Firstly, utm_source pinpoints the traffic source. In email marketing, you’d typically label this with your email platform or email type, like utm_source=mailchimp, utm_source=weekly_newsletter, or utm_source=email_broadcast.
Secondly, utm_medium specifies the marketing channel, consistently set as email for email links, such as utm_medium=email, to distinguish email traffic from others like social media or paid search.
Thirdly, utm_campaign names the specific email campaign or promotion, aiding in performance comparison over time with tags like utm_campaign=june_promo_2025.
Fourth, utm_content, although optional, helps differentiate links within the same email or during A/B tests, like utm_content=header_logo_link vs. utm_content=cta_button.
Lastly, utm_term, though less common in email marketing, could differentiate segments within a campaign if not covered by the campaign name or content tags.
When recipients click on links with UTM parameters, the data is relayed to your analytics platform, enabling precise tracking of the impact of email campaigns and specific links on your website traffic, engagement, and conversions.
Most email marketing platforms offer tools for automatic UTM parameter addition, or you can use resources like Google’s Campaign URL Builder.
