How can using UTM parameters in your email marketing help measure success? As you know, email marketing is one of the most effective ways to connect with customers, promote products, and drive sales. But understanding which emails generate traffic and conversions is essential to your business’s success.
UTM parameters provide valuable insights into how subscribers interact with your campaigns after clicking a link. They help you identify which emails drive traffic, which promotions generate conversions, and where your marketing efforts are paying off. Understanding how to use UTM parameters can help you make smarter decisions, optimize future campaigns, and improve your email marketing ROI.
Let’s dig in.
UTM Parameters in Email, Defined
UTM (or Urchin Tracking Module) parameters are short pieces of tracking information added to the end of a URL. They allow analytics platforms like Google Analytics to identify where website traffic originates and which marketing campaigns bring visitors to your site.
When a subscriber clicks a link containing UTM parameters, the tracking information travels with the URL. Then, your analytics platform can use that information to categorize the visit and associate it with a particular marketing campaign.
For example, a basic website URL might look like this:
https://example.com/sale
With UTM parameters, it might look like this:
https://example.com/sale?utm_source=newsletter&utm_medium=email&utm_campaign=summer_sale
Both links lead to the same webpage—however, the second URL provides information about the visitor’s source, marketing channel, and campaign.
What UTM parameters don’t do is track email opens or personally identify subscribers. Instead, they help connect email marketing activity with website behavior, offering a different and valuable piece of information.
Why Are UTM Parameters Important for Email Marketing?
Most email marketing platforms provide metrics such as open rates, click rates, and unsubscribes. While these metrics are important, they don’t tell the entire story. What happens after someone clicks your email? Do they browse your website, download a resource, complete a form, or make a purchase? We’re sure you’d like to know!
UTM parameters help bridge the gap between email engagement and website performance. By using UTM tracking, businesses can identify which campaigns generate the most traffic, compare different promotional strategies, and understand which emails contribute to conversions.
For example, imagine you’re running three email campaigns promoting a seasonal sale. Each campaign generates a similar number of clicks, but one produces significantly more purchases. UTM tracking can help reveal that difference. Instead of relying solely on clicks, you can evaluate campaigns based on meaningful business results.
The 5 Types of UTM Parameters Explained
There are five commonly used UTM parameters, each providing different information about your website traffic.
#1 – utm_source
This parameter identifies the source of the traffic. For email marketing, it might be your newsletter, a particular email program, or another consistently named source.
Example: utm_source=newsletter
# 2 – utm_medium
The medium identifies the marketing channel responsible for the visit. For email campaigns, the recommended value is typically email. Using a consistent medium helps Google Analytics categorize your email traffic.
Example: utm_medium=email
#3 – utm_campaign
This parameter identifies the specific marketing campaign associated with the link. It can describe a product launch, seasonal promotion, or special event. Campaign names make it easier to compare results across different promotions.
Example: utm_campaign=summer_sale
#4 – utm_content
The content parameter differentiates links or creative elements within the same campaign. For example, you might use separate values for a headline link and a call-to-action button. This allows you to compare which elements attract valuable traffic.
Example: utm_content=shop_now_button
#5 – utm_term
Originally designed to track paid search keywords, this optional parameter can also be used for additional campaign classifications. However, most email campaigns don’t require this parameter.
Example: utm_term=vip_customers
Google Analytics supports additional campaign parameters, but these five are the traditional foundation of UTM tracking.
How to Create UTM Parameters for Your Email Campaigns
Good news here—this is a relatively simple task. You can build tagged URLs manually or use a URL builder.
Start with the webpage you want subscribers to visit. This might be a product page, landing page, blog article, or promotional offer.
Next, identify your campaign’s source, medium, and name. Add optional parameters if you want to differentiate specific links.
For example:
https://example.com/shop?utm_source=newsletter&utm_medium=email&utm_campaign=summer_sale&utm_content=hero_button
In this example, the URL identifies traffic from a newsletter promoting a summer sale, specifically through the hero button.
You can create URLs using Google’s Campaign URL Builder or the UTM tracking features available in many email marketing platforms, like Mailchimp and Klaviyo, which make it even easier for you.
Pro tip: Before sending your campaign, test every tagged link to ensure it directs subscribers to the correct page and preserves the tracking information.
Different Uses for UTM Parameters in Email Marketing
UTM parameters aren’t limited to promotional newsletters. They can be useful across almost every type of email marketing campaign.
- Promotional emails: Track traffic and purchases resulting from discounts, product launches, and seasonal sales. This allows you to compare campaigns to determine which offers generate the best results.
- Welcome emails: Understand how new subscribers interact with your website after joining your list. You’ll be able to identify whether welcome messages encourage browsing, account creation, or purchases.
- Abandoned cart emails: Measure how many visitors return to your website through cart recovery messages and complete their purchases.
- Newsletters: Discover which articles, resources, and featured products encourage subscribers to explore your website.
- Automated email sequences: Compare the performance of individual messages within a welcome, nurturing, or re-engagement sequence.
- A/B testing: Use the utm_content parameter to distinguish different buttons, images, or creative variations and evaluate their website performance.
UTM tracking helps marketers understand not just which emails get clicks, but which messages encourage meaningful actions.
How to Track Email Campaigns in Google Analytics
Once you’ve added UTM parameters to your email links, you can analyze campaign performance in Google Analytics 4 (GA4). Begin by signing in to your Google Analytics account and selecting the appropriate property.
Then, follow this path: Navigate to Reports → Acquisition → Traffic acquisition. This report shows where website visitors come from, including email marketing campaigns.
To examine email performance, select a relevant dimension such as Session source / medium or Session campaign. You can then filter your data to focus on email traffic or individual promotions. Depending on your analytics configuration, you can review metrics such as sessions, engaged sessions, engagement rate, key events, and revenue. For more detailed comparisons, use GA4 Explorations to examine individual campaigns and tagged content variations.
Remember that accurate reporting depends on proper Google Analytics installation, consistent UTM naming, and correctly configured conversion events.
UTM Parameter Best Practices for Email Marketing
UTM tracking works best when you follow a consistent approach. Poorly organized tracking can produce confusing reports and make campaign comparisons difficult.
Here are several best practices to follow:
- Use consistent naming conventions. Decide how your team will name campaigns, sources, and mediums.
- Stick with lowercase letters. Google Analytics treats uppercase and lowercase parameter values differently.
- Keep campaign names descriptive. Use meaningful labels such as summer_sale rather than generic names.
- Avoid unnecessary parameters. Include information that supports your reporting goals without making URLs overly complicated.
- Check for automatic UTM tagging. Some email marketing platforms add parameters automatically, so avoid duplicating them.
- Test links before sending. We cannot say this enough. Verify that tracking parameters remain intact and landing pages load correctly.
- Protect subscriber privacy. Never include email addresses, names, or other personally identifiable information in UTM values.
It’s also important to avoid using UTM parameters for links between pages on your own website. Internal UTM links can interfere with accurate traffic attribution.

How to Measure Email Marketing ROI Using UTM Parameters
One of the biggest advantages of UTM parameters is their ability to connect email campaigns with business outcomes. Rather than measuring success solely through opens and clicks, marketers can use tagged traffic alongside conversion and revenue data to evaluate campaign profitability.
For example, suppose you spend $500 creating and sending a promotional email campaign. Google Analytics then attributes $2,000 in revenue to that campaign under your selected attribution model. You can calculate a simple revenue-based ROI using this formula:
ROI = (Revenue − Campaign Cost) ÷ Campaign Cost × 100
In this example:
($2,000 − $500) ÷ $500 × 100 = 300% ROI
This simplified calculation assumes revenue is the return being measured. For a more accurate profitability assessment, include product costs, discounts, and other expenses.
UTM parameters don’t calculate ROI automatically. They provide campaign attribution information that can be combined with revenue and cost data. Also, attribution isn’t always perfect. Customers may interact with several marketing channels before purchasing, so analytics reports may assign credit differently depending on the attribution model.
Nevertheless, UTM tracking provides valuable evidence about which campaigns contribute to sales, leads, and other important business goals.
Make Every Email Click Count
Simply put, understanding UTM parameters in email marketing can transform how you measure campaign success. By adding basic tracking information to your links, you gain greater visibility into where website traffic comes from and how subscribers interact with your business.
From promotional newsletters to automated email sequences, UTM parameters help you compare performance, identify successful strategies, and make more informed marketing decisions.
When combined with Google Analytics and consistent tracking practices, UTM parameters provide a clearer picture of your email marketing efforts. Start incorporating them into your campaigns to better understand your results, optimize future emails, and maximize your marketing ROI.
