Understanding Metrics to Measure Direct Mail Marketing
Before getting into specific formulas and methods, it’s helpful to understand the key metrics that will help you measure direct mail marketing success:
- Response rate: The percentage of recipients who respond to your direct mail piece.
- Conversion rate: The percentage of recipients who take a desired action, such as scheduling a consultation.
- Return on Investment (ROI): The amount of dollars you get in return for every 1 dollar you pay. Use our free tool to check the profitability of your direct mail campaign.
- Cost Per Lead (CPL): The average cost of generating a lead through direct mail.
These metrics will help you assess your campaign’s effectiveness, identify areas for improvement, and demonstrate the science behind what drives the success of direct mail marketing.
69% of consumers engage with direct mail weekly, and one in three do so daily.
Media Logic
Calculating the Response Rate
Measuring the response rate is the first step in understanding how well your direct mail campaign is performing.
This key metric shows how many recipients engaged with your mailer (i.e. call you, scans a QR code, visits your website, etc.).
Knowing your response rate will give you insight on how effective your mailers are at getting people to take action.
Response rate (%) = (number of responses/number of mailers sent) x 100
For example, if you sent out 1,000 postcards and received 50 responses, your response rate would be:
Response rate (%) = (50 / 1,000) x 100 = 5%
A response rate of 2-5% is generally considered good for direct mail campaigns, but this can vary depending on the industry and the quality of your mailing list.
Measuring the Conversion Rate
While getting responses is great, the real value lies in conversions.
The conversion rate reveals how many of those responses actually led to meaningful actions, such as scheduling an appointment or making a purchase.
In real estate, this could be attending an open house or calling for more information. In the retail industry, it might be making a purchase or signing up for a loyalty program.
The conversion rate gives you a clearer picture of your campaign’s effectiveness.
Conversion rate (%) = (number of conversions / number of responses) x 100
If out of those 50 responses, ten people ended up scheduling a consultation with you, your conversion rate would be:
Conversion rate (%) = (10 / 50) x 100 = 20%
This metric is important because a high response rate is positive, but if those responses don’t result in conversions, the campaign’s overall effectiveness is reduced.
Determining the Return on Investment (ROI)
Your direct mail ROI is the ultimate measure of success for any marketing campaign.
It calculates whether your direct mail efforts were financially worthwhile by comparing the revenue generated to the campaign’s cost.
In short, it tells you how many dollars you get back for every 1 dollar that you spend.
ROI (%) = [(revenue generated – campaign cost) / campaign cost] x 100
Let’s say your campaign cost $2,000, and it generated $10,000 in revenue from new clients. Your ROI would be:
ROI (%) = [($10,000 – $2,000) / $2,000] x 100 = 400%
In the above example, you effectively make $5 for every $1 spent, which includes $4 in profit and the return of your initial $1 investment—resulting in a 400% return on investment.

Calculating the Cost Per Lead (CPL)
CPL is the amount of money you spend to get each new potential customer. It shows how much it costs to generate one lead from your marketing efforts.
For example, if you spend $2,000 and get 50 leads, your CPL is $40, meaning you spent $40 to get each lead.
The goal is to keep your cost per lead as low as possible and to find ways to reduce it even more.
CPL = campaign cost/number of leads generated
If your campaign cost $2,000 and you generated 50 leads, your CPL would be:
CPL = $2,000/50 = $40 per lead
A lower CPL indicates a more efficient campaign, though it’s also important to consider the quality of the leads.
Using Tracking Tools and Methods to Measure Direct Mail Marketing Campaigns
Thanks to the advancement of modern technology, we have a few different options to measure our direct mail marketing efforts:
- Unique tracking codes: Add unique promo codes or URL to your mailers that recipients can use when responding. This lets you connect responses directly to your campaign and see what’s working.
- Dedicated phone lines: Set up an unique phone number specifically for the your direct mail campaign. This lets you track the number of inquiries generated by your mailer.
- PURLs (Personalized URLs): Use personalized URLs that lead recipients to a landing page created specifically for them. This allows you to see who’s responding and how they’re engaging with your content.
- QR codes: QR codes provide a quick way for recipients to visit your website or landing page. By tracking scans, you can measure how effectively your mailer drives online interactions.
- Split testing: Split testing means sending out different versions of your mailer—maybe with a different headline, image, or special offer—to see which one your audience likes best.
These methods give you direct insight into your campaign’s effectiveness and will help you fine-tune your strategy over time.

Practical Examples of Measuring Direct Mail Success
REALTOR
An effective example of measuring direct mail marketing comes from Kirk Weingarten’s efforts in the Florida real estate market.
By tracking and analyzing the results of their direct mail campaigns, Kirk and his wife turned a $400 per mail campaign investment into nearly $100K in earnings, achieving a 10x return on investment.
Their strategy focused on the $600,000 home market, a segment they identified as having significant potential.
Targeting this niche with direct mail postcards led to securing six listings within the first year.

Kirk’s ability to monitor the effectiveness of his mail campaigns allowed him to adjust his approach, optimizing each dollar spent for better results.
The link between their focused mailing strategy and the business outcomes proves the value of being data-driven in direct mail marketing.

Dr. Johnna Thomas, a dentist in Leawood, Kansas, aimed to grow her practice, Restore Dental KC, by targeting new movers in her area through direct mail marketing.
Dr. Thomas focused her mailings on residents who had recently moved into the community, a strategy designed to reach individuals likely in need of a new dentist.
