How to Track Email Marketing ROI
Tracking the return on investment (ROI) of your email marketing campaigns is crucial for understanding their effectiveness and ensuring that your efforts are generating tangible results. ROI helps you measure how well your email campaigns are contributing to your business goals, such as increased sales, lead generation, or customer retention. In this article, we’ll explore how to track email marketing ROI, with real-world examples to illustrate the process.
1. Understand the Formula for Email Marketing ROI
To calculate the ROI of your email marketing campaigns, you'll need a clear formula. The basic formula for ROI is:
ROI=(Revenue from Campaign−Cost of CampaignCost of Campaign)×100\text{ROI} = \left( \frac{\text{Revenue from Campaign} - \text{Cost of Campaign}}{\text{Cost of Campaign}} \right) \times 100
This formula helps you determine how much revenue your email campaign generated in relation to the cost incurred to run it.
Example:
Let’s say your company spent $1,000 on an email marketing campaign, which generated $5,000 in revenue. The ROI calculation would be:
ROI=(5,000−1,0001,000)×100=400%\text{ROI} = \left( \frac{5,000 - 1,000}{1,000} \right) \times 100 = 400\%
This means you earned four times the amount you spent, indicating a successful campaign.
2. Track Revenue Directly Attributed to Email Campaigns
One of the most direct ways to track email marketing ROI is by attributing revenue specifically generated from email campaigns. This can be done by tracking sales, conversions, or leads that came from a link or promotion in your email.
Example:
A clothing retailer runs an email marketing campaign offering a 20% discount code. They track how many purchases were made using that code, and they can directly attribute that revenue to the email campaign.
If 200 customers used the discount code, and the total revenue from those purchases was $4,000, this amount is directly tied to the campaign. Using the ROI formula:
ROI=(4,000−500500)×100=700%\text{ROI} = \left( \frac{4,000 - 500}{500} \right) \times 100 = 700\%
The campaign cost $500 to create and send, and it generated $4,000 in sales, providing a 700% return.
3. Use UTM Parameters to Track Campaign Performance
UTM (Urchin Tracking Module) parameters are unique tags added to the links in your emails, helping you track the source, medium, and campaign in your analytics platform, such as Google Analytics. This method is particularly useful for tracking the performance of your emails and attributing conversions accurately.
Example:
Let’s say a software company sends an email campaign with a link to a landing page offering a free trial of their service. They add UTM parameters to the link like this:
https://www.example.com/trial?utm_source=email&utm_medium=cpc&utm_campaign=free_trial_march
By using UTM parameters, the company can track how many visitors from the email click the link, how many sign up for the free trial, and ultimately how many convert to paying customers. This allows them to attribute any revenue to the email campaign and calculate ROI more accurately.
4. Calculate Customer Lifetime Value (CLV) for Long-Term Campaigns
Email marketing isn’t always about short-term sales. For many businesses, the true value of email marketing comes from building relationships that lead to repeat customers. Customer Lifetime Value (CLV) is a key metric to consider when measuring long-term ROI, as it helps you understand the long-term revenue potential of a customer acquired through email.
Example:
A subscription box company sends a series of welcome emails that result in 100 new customers signing up for a monthly subscription. While the immediate revenue from the initial sign-up might be $5,000, the real ROI comes when you factor in the lifetime value of each customer.
If the average customer stays subscribed for 12 months and pays $50 per month, the customer’s CLV is $600. With a cost of $1,000 for the email campaign, the ROI calculation becomes:
ROI=(600×100−1,0001,000)×100=59,000%\text{ROI} = \left( \frac{600 \times 100 - 1,000}{1,000} \right) \times 100 = 59,000\%
This calculation illustrates that while the immediate return was modest, the long-term value generated by these customers significantly outweighs the campaign cost.
5. Account for Non-Monetary Benefits
Not all email marketing campaigns are focused on direct revenue generation. Some campaigns aim to increase brand awareness, customer engagement, or website traffic. While these may not immediately show a high ROI in terms of direct revenue, they can contribute to long-term business growth.
Example:
A nonprofit organization sends an email campaign to promote its upcoming charity event. While the campaign doesn’t directly generate money, it drives traffic to the event registration page, and attendees make donations at the event. By tracking how many attendees were driven by the email, the organization can calculate the overall impact of the campaign.
Even though the email didn’t generate direct revenue through clicks or purchases, the donation from attendees can still be considered part of the ROI calculation.
6. Measure the Effectiveness of Different Email Types
To refine your email marketing strategy, it’s important to measure the ROI of various types of email campaigns. Some emails might generate more immediate sales, while others may focus on nurturing leads or engaging current customers.
Example:
An e-commerce company sends out three different types of email campaigns in a month: a product promotion email, an abandoned cart reminder email, and a newsletter. By tracking the revenue generated from each type of email, the company can determine which campaigns are the most effective at generating sales and adjust their future email strategy accordingly.
For instance, the product promotion emails might generate $10,000 in sales, while abandoned cart emails bring in $2,000. By tracking the ROI for each type of email, the company can better allocate their resources for future campaigns.
7. Use Email Marketing Software for Tracking
Email marketing platforms like Mailchimp, HubSpot, and ActiveCampaign come with built-in analytics to help you track key metrics like open rates, click-through rates, and conversions. These platforms also offer ROI tracking tools that can integrate with your eCommerce platform or CRM, providing a seamless way to track revenue directly generated from email campaigns.
Example:
A SaaS company uses HubSpot to track email performance. They send an email offering a limited-time discount on their software. HubSpot automatically tracks how many people clicked the link, signed up for the software, and made a purchase. The company can then use this data to calculate ROI without manually linking email performance to sales data.
