We’ll discuss the components contributing to direct mail ROI and how automation enhances scalability, reduces manual effort, and ensures consistency in your direct mail campaigns.

Understanding direct mail ROI

What is ROI, and why is it important in marketing

ROI, or return on investment, is a key metric used to measure the success of marketing efforts. It indicates the amount of profit generated from a particular campaign or tactic compared to its cost. Essentially, it shows how much value you are getting for every dollar spent.

Definition and importance of direct mail ROI

Direct mail return on investment is the quantitative measurement of the value generated from your direct mail marketing efforts in relation to the costs incurred. It goes beyond mere financial figures, providing insights into the overall impact of your campaigns, the responsiveness of your audience, and the success of your messaging. As a critical metric, direct mail marketing ROI empowers you to assess the value of your direct mail marketing efforts, enabling informed decision-making and resource allocation.

Did you know? 

  • 84% of marketers agree that direct mail delivers the highest conversion, response, and ROI of any channel
  • 69% of marketers believe their company can determine the ROI of its direct mail efforts and accept that typical methods used to measure it are generally reliable 
  • These numbers have consistently increased year-over-year for the third consecutive year, suggesting that direct mail has consistently earned its place as a channel that marketers can depend on to deliver results

How does direct mail compare to digital channels in terms of ROI? 

Direct mail ROI is consistently high compared to digital channels. While digital channels may offer lower costs per lead and higher response rates, they often fall short in terms of actual conversions and revenue generated. This is because direct mail offers a tangible, physical presence that cannot be ignored or easily deleted like an email or online ad.

Moreover, direct mail also boasts a longer lifespan compared to digital marketing efforts. A physical piece can sit on someone's desk or be kept as a reminder for weeks or even months, whereas the impact of a digital message typically fades much quicker.

The role of direct mail automation in optimizing ROI

Harnessing technology to streamline processes and enhance efficiency has become paramount in scaling marketing operations. Direct mail automation has transformed the landscape of traditional manual-intensive direct mail campaigns. By seamlessly integrating data-driven insights and personalized content, automation empowers you to connect with your audience in a more targeted and relevant manner, increasing response, conversion, and ROI.

Key factors influencing direct mail ROI

Cost of direct mail campaigns

The cost of direct mail can vary greatly depending on the size and scope of the campaign. However, some general costs can be expected.

  1. Printing - the cost of paper, ink, and printing itself
  2. Postage - the cost to send the direct mail piece to its destination
  3. Production - includes design and production costs, as well as any mailing list acquisition costs (e.g., paying copywriters, designers, or anyone else involved in the process)

It's important to consider these costs when selecting a direct mail platform or agency. Many offer flat-rate pricing, including all the costs mentioned above. Budgets for direct mail run the gamut from 5-50%, with smaller companies spending larger portions of their budgets on direct mail than larger organizations. In the 2023 State of Direct Mail, 58% of marketers reported having more marketing budget allocated to direct mail than in 2022.

Response rates and conversion rates

The average response rate for direct mail marketing is typically around 3% to 5% for existing customers and 1% to 1.5% for new prospects, according to the Data & Marketing Association. Your conversion rate will, of course, be a lower percentage of those who respond. That rate will depend on your offer.

Remember that the response rate for direct mail can vary based on industry and type of direct mail. Consider how response rate for direct mail averages differ across types of sends:

  • House vs. prospect lists: The ANA reported that the average for house lists is 9%, while the average for prospect lists is 5%
  • Direct mail type: The ANA reported that oversized envelopes have the greatest household response rate, followed by postcards and then letters.
  • Type of campaign: Retention campaigns are most likely to have a response rate higher than 10%, while acquisition campaigns are typically in the 5–10% range.

Compare these results with your response rate for direct mail to gauge the health of your direct marketing.

Target audience selection and segmentation

Target audience selection and segmentation are crucial for the success of a direct mail campaign. To effectively reach your target audience, you need to understand their demographics, behaviors, interests, and preferences.

Segmenting your audience allows you to tailor your messaging and offers specifically to different groups within your target market. This can lead to higher response rates and conversions because the message resonates more with the individual receiving it, and thus boost direct mail marketing ROI.

Consider using data analytics tools to help identify and segment your target audience. These tools can provide valuable insights into customer behavior and help you create more targeted campaigns and improve the value of every send.

Design and personalization strategies for increased response rates

In addition to targeting the right audience, the design and personalization of your direct mail pieces can also impact response rates. Personalized and visually appealing mailers have been shown to generate higher response rates compared to generic, mass-produced ones.

Lob's HTML templates allow you to include personalization tokens and dynamic content, such as names, locations, or personalized offers, to make each direct mail piece feel more tailored and relevant to the recipient. You can even personalize images and design.

Lob's template gallery includes professional designs optimized to boost your direct mail ROI. Choose from postcards, letters, self-mailers, and more to create eye-catching and personalized mail pieces that grab the attention of your target audience. Just tailor each template to your needs.

If you'd rather use your own designs, Lob integrates with design tools like Figma and Adobe InDesign so you can convert your files to customizable HTML mail templates at the push of a button. Learn more about Lob integrations here.

Testing and optimization techniques to improve ROI

No matter how well you target and design your direct mail pieces, there will always be room for improvement. That's where testing and optimization come in.

A/B testing is a common technique marketers use to compare two versions of a direct mail piece and determine which one performs better in terms of response rate, conversion rate, or revenue generated. For example, you could test different call-to-action phrases, images, or offers to see which combination resonates best with your target audience.

Lob’s HTML creative lets you personalize content for each recipient and compare the impact of content via A/B and multivariate testing. Test direct mail alongside email and digital ads to see what messaging and segments drive the best ROI in different channels. Integrate Lob with your CRM or CDP to track ROI across your entire marketing landscape.

Calculating direct mail ROI

ROI formula and its significance

For every direct mail campaign you send, you want to measure the impact by looking at the return on investment (ROI). Similar to the revenue generated per mail piece, this metric reflects how much money the campaign generates. However, unlike the previous calculation, ROI compares the revenue earned to the cost of the campaign.

To calculate your direct mail ROI, you'll need the total revenue generated and the total cost of the campaign. Then, plug those into this formula:

Direct Mail ROI Formula

(Total Revenue-Total Cost)/(Total Cost)

The final number is a percentage you can use to compare your ROI with other marketing initiatives.

Benefits of direct mail automation on ROI

Streamline direct mail campaign management

Direct mail comes with plenty of complexities, and without an effective strategy, and streamlined workflow, the process can become immensely time and resource-intensive.

Does it take you months to execute a direct mail campaign? Do you struggle with long lead times when sending postcards, letters, checks, or other direct mail formats? If so, you can modernize your direct mail process for a more effective and efficient omnichannel customer experience. Cutting out manual processes to transition to direct mail automation can be a game-changer as it saves time, increases ROI, and enables you to automate and trigger direct mail based on customer behavior.

Automated direct mail is more efficient

Direct mail campaigns can seamlessly complement digital activities, especially when leveraging modern tools and cloud software. Best of all, when you transition to automation, you can use direct mail in new ways. For example, you can add more precise timing and enhance personalization, garnering increase response and ROI.

Automate direct mail list management and data processing

The first step to any successful direct mail program is the ability to piece together an audience list for effective targeting. This is because reaching customers with direct mail that is relevant and contextual to their needs can maximize your responses and lead to better ROI. The days of sending mail indiscriminately to every household within a given area using the "spray and pray" method are long over.   

However, good audience segmentation and targeting depend heavily on having quality data, which can impact how your mail is planned, produced, mailed, and ultimately, how consumers take action on it. Many automated direct mail platforms, like Lob,  provide various ways to improve your address data hygiene and deliverability and augment your first-party data with additional datasets to increase reach.

In addition, marketers are proactively using Address Verification before sending their campaigns to ensure address accuracy and validity and decrease wastage. Postal address verification allows senders to ensure their mail will be deliverable and that location is valid (addresses are valid if they are CASS-certified). This process ensures the highest possible ROI while helping mailers maintain their database's integrity over time. Lob's software provides address verification APIs, which verify each recipient's address and ensure proper formatting. Any address can be verified in seconds, and a Lob confidence score is given (e.g., 100% likelihood of being deliverable).

Simplify printing, addressing, and fulfillment

The magic of direct mail automation is that it transforms manual, repetitive processes to accelerate time to value, reduce costs, and supercharge ROI. The result is intelligent direct mail that is connected, personalized, and scalable.

We automated all of it—from making sure members were providing deliverable addresses to programmatically sending postcards on-demand. - Denise Remhof, Product Manager, Couchsurfing


A direct mail automation platform enables you to automate the process end-to-end, from creation to printing to fulfillment. 

Building an automated direct mail campaign in Lob

Instead of campaigns taking months, you can set up and execute direct mail campaigns in minutes. You can schedule ahead, send last-minute, or trigger campaigns based on customer behaviors or events. Direct mail automation platforms often have Print Delivery Networks that replace traditional print vendor relationships with an integrated, on-demand network of distributed commercial printers, streamlining and simplifying the process so your mail is always a priority. At any scale and frequency.

Direct mail personalization at scale

Brands that are doing personalization well not only stand out from the competition but deliver the results they need to grow and position themselves as leaders in their categories. They deliver ROI and revenue and create the kind of memorable customer experiences that consumers crave. 

68% of consumers are more likely to engage with a brand’s message when personalized, but many brands simply use a consumer’s first name and think that’s good enough. 52% of consumers expect their direct mail to be personalized, so give them what they want and go beyond Dear {First_Name} to drive the best response and ROI.

Direct mail personalization for better ROI

Dynamic content for personalized messaging

Consumer data is the key to personalization. The more you know about a consumer, the more you can customize your marketing and direct mail to meet their tastes, needs, and challenges. Your company likely already has the personalization information you need in your sales and marketing tech stack, such as: 

  • Customer data sources: CRM, marketing automation platforms, and other databases
  • Contact lists: email, mailing lists, and sales contacts
  • Online behavior tracking: Browser behavior and customer purchases

Your goal is to form as complete a picture as possible of your customers. Demographics, previous purchases, interests, contact history, and other data you have will enable you to personalize your direct mail campaigns. 

thredUP, a managed online clothing marketplace, uses Lob to automate its direct mail retention campaigns. Using Lob’s HTML templates, thredUP began sending postcards to existing customers that had the potential to churn. The postcards featured images and recommendations based on customers' previous purchases and discounts. 

All the content was dynamically populated, from the brand suggestions and images to the discounts' expiration dates. That meant thredUP could customize each postcard to the customer’s purchase history automatically, without redesigning, requirements gathering, or other time-consuming tasks. 

We’ve seen a 25% increase in order rate from the customers we target with Lob campaigns. - Anthony Marino, President, thredUP

That doesn’t mean every campaign needs to involve deep customer insights. You can get excellent results by targeting customers based on their most recent purchases. But having extensive customer data enables you to better segment, target, and personalize your mailers. You can also personalize your campaigns using personalized maps from the consumer’s home to the nearest physical location or use personalized tracking tactics like 1:1 QR codes or PURLs (personalized URLs) to give each campaign a bespoke touch.

Data-driven decision-making

Many businesses find that managing and optimizing their direct mail campaigns can be disjointed, with little or no data available to track performance. And if you can’t track it, you can’t improve it. 

Analyzing campaign performance in real-time

Just like you can’t personalize your campaigns without data, you can’t analyze their efficacy without data. Automation platforms provide real-time visibility into campaign performance metrics so you can see what’s working and what isn’t and make adjustments. 

direct mail analytics to measure ROI

You can also integrate your direct mail automation platform with other parts of your marketing tech stack to get the necessary data to fully attribute your campaigns, measure and report direct mail ROI, show revenue and conversion lift, and execute multivariate tests. 

Case studies: Direct mail ROI success stories

iExit: Optimizing direct mail format for higher conversions

iExit is a free travel and map app for road trippers and provides information about highway exits for travelers. Its business model operates on advertising revenue through business sponsorships for exits, but it was proving impossible for iExit to find the business owners’ digital contact information to sell sponsorships. 

Direct mail fuels measurable results 

iExit tested several direct mail formats and discovered that letters outperformed postcards for its target audience. Through conversations with prospective customers, the iExit sales team learned the most commonly asked questions and included the answers in its direct mail campaigns. 

“We needed more space for information which is how we ended up with a two-page letter, and the second page, the FAQ page, was a big turning point in boosting conversion rates.” - Evan Metrock, Founder & CEO

The boost in conversion rates equated to a 40% increase in users claiming their business listing on the app and a 60% increase in purchased sponsorships. iExit’s direct mail acquisition campaigns are essentially self-running,  thanks to automation which continues to drive predictable and profitable results.

We tested a campaign and got immediate results with an ROI of 155%. Not only could it scale, but direct mail was profitable right off the bat. - Evan Metrock, iExit Founder and CEO

VentureStack: Integrating direct mail with digital channels for enhanced ROI

Direct mail for the real estate investing market hasn’t changed much in the last decade resulting in many firms using very similar-looking boilerplate mail. 

Because of the limiting templates, VentureStack struggled to stand out from the competition in acquiring new home-selling clients with its direct mail campaigns. VentureStack was also getting hamstrung by the manual, time-consuming nature of executing its direct mail campaigns. 

VentureStack began using Lob in its new customer acquisition campaigns. It found near immediate success with a two-page letter. VentureStack has also had success using direct mail postcards. Its postcard includes a QR code to drive traffic to its website leading prospects to fill out a form. It then uses a Facebook pixel and pixels on its website to retarget and capture leads.

"Direct mail has been a nice complement to our online initiatives. We’ve found that many people who receive direct mail will never pick up the phone and call us, but they'll check us out online. It's a highly effective way to drive traffic to our online presence. And then, we have the protocol set up with retargeting and recapturing that information to be able to monetize that later on down the line." - Tim McGarvey, Co-Founder, VentureStack

The most important metric VentureStack uses to measure the efficacy of its direct mail campaigns is return on ad spend (ROAS), essentially return on investment. It tracks each campaign with an individual phone number. 

In our industry, companies normally target a 4 to 5 times return to be a viable, sustainable marketing channel. We have an 8.3 return on ad spend from direct mail, so we're blowing that out of the water.

McGarvey and his team only realized how successful their direct mail campaigns were once they met with other companies and started benchmarking results. They quickly realized they had very successful campaigns and decided to double down on direct mail marketing and optimize what worked. 

VentureStack plans to continue scaling up its direct mail marketing and has shifted 90% of its marketing budget to the channel.

Monitoring and analyzing campaign performance

It's important to monitor and analyze the performance of your direct mail campaign so that you can see what's working and what's not, as discussed in the analytics section of this guide. This will help you make necessary adjustments to your campaign and improve your ROI. 

Create compelling offers and incentives

In addition to crafting compelling copy and visuals, it's important to offer your audience something of value. This could be a discount code, a free trial or sample, or an exclusive offer for being a part of your mailing list. These incentives can help motivate your audience to take action and increase the success of your direct mail campaign. It's essential to regularly review and update these offers to keep them relevant and engaging for your target audience.

This allows for a more personalized and targeted approach to marketing, increasing the chances of conversion.

While consumers report receiving too much email, according to our 2024 State of Direct Mail Consumer Insights report, many are comfortable receiving even more direct mail than they already do. But the highest ROI will undoubtedly come from building a strong and personalized omnichannel strategy that caters to the wants and needs of consumers.
