Direct mail is a form of marketing that uses physical mail to reach an audience. It includes postcards, letters, and brochures sent to people's homes or businesses. While it has existed for decades, modern tools make it possible to send more personalized and data-driven mail than ever before.

Targeted direct mail is different from mass mailings. It focuses on sending messages to specific people based on their characteristics, behaviors, or preferences. Instead of sending the same message to everyone, targeted mail uses data to tailor content for each recipient or group.

This article outlines key best practices for running successful targeted direct mail campaigns. Each section breaks down a core part of the process, from building your list to testing and improving your results.

Understand Your Audience for Targeted Mail Marketing

Knowing who you're sending mail to is the first step in targeted direct mail marketing. Unlike mass mailings that blast the same message to everyone, targeted mail uses data to reach specific groups with relevant messages.

To understand your audience, create detailed profiles using different types of data:

  • Purchase history: Shows what products people buy and how much they spend
  • Engagement data: Reveals how people interact with your brand across channels
  • Demographic information: Tells you who your customers are (age, income, location)
  • Geographic location: Helps you target by neighborhood or region

At Lob, we've seen that campaigns with detailed audience profiles perform significantly better than generic mailings. When you know who you're talking to, you can create messages that actually matter to them.

Maintain an Accurate Mailing List for Direct Mail Best Practices

Your mailing list directly impacts how well your campaign performs. According to USPS, about 40 million Americans change their address each year. If your list contains outdated addresses, you waste money on undeliverable mail.

1. Cleanse and Validate Your Addresses

Keep your list clean with these methods:

  • NCOA processing: Checks addresses against USPS change-of-address records
  • CASS certification: Verifies addresses meet postal formatting standards
  • Address standardization: Formats addresses consistently for reliable delivery
  • Duplicate removal: Eliminates multiple entries for the same household

Lob automates address verification, reducing undeliverable mail and saving you money on wasted postage.

2. Use Segmentation for Relevant Offers

Divide your list into groups with similar traits to send more relevant messages:

Segmentation Type Example Application
Demographic Send student loan offers to people aged 18-24
Behavioral Re-engage customers who haven't purchased in 6 months
Geographic Promote local store events to nearby neighborhoods
Lifecycle Welcome new customers with special first-time offers


Segmented campaigns
typically see response rates 4-10 times higher than non-targeted campaigns, according to the Direct Marketing Association. This means better results for the same budget.

Apply Direct Mail Design Best Practices to Stand Out

Design affects how people respond to your mail. A well-designed piece guides the reader's attention and makes your message clear.

1. Choose Eye-Catching Formats

Select the right format for your goals:

  • Postcards: Quick to read, lower cost, great for simple offers
  • Letters: More professional, good for detailed information
  • Self-mailers: No envelope needed, combines visual impact with more space
  • Dimensional mail: Packages or boxes that stand out in the mailbox

Each format works best for different situations. Postcards work well for reminders and simple promotions, while letters are better for financial offers or detailed information.

2. Showcase Your Brand and Message Clearly

Make your mail easy to understand at a glance:

  • Use visual hierarchy: Place your most important message where it will be seen first
  • Keep colors consistent: Use your brand colors to build recognition
  • Choose readable fonts: Stick to 1-2 font styles that are easy to read
  • Use white space: Don't crowd your design with too much information

Lob's templates help you create professional designs that follow these principles, even if you don't have a design team.

Craft Direct Mail Creative Best Practices That Motivate Action

The words and images you use in direct mail creative make a big difference in whether people respond to your mail.

1. Write Headings That Grab Attention

Your headline is the first thing people read. Increase your open rates with these proven headline approaches:

  • Ask a question: "Ready to Save on Your Energy Bill?"
  • Use numbers: "3 Ways to Improve Your Credit Score"
  • State a benefit: "Get More Sleep Starting Tonight"
  • Create curiosity: "The Surprising Reason Most Diets Fail"

Keep headlines short and focused on what matters to the reader. Different industries have different effective approaches, but clarity always wins.

2. Offer a Clear and Urgent CTA

Your call-to-action (CTA) tells people exactly what to do next:

  • Make it visible: Use contrasting colors and place it prominently
  • Keep it simple: "Call Today," "Visit Our Website," "Scan to Save"
  • Create urgency: Add time limits like "Offer Ends Friday"
  • Make response easy: Include QR codes, simple URLs, or prepaid response cards

The easier you make it for people to respond, the more likely they will. At Lob, we've found that clear, single CTAs typically outperform pieces with multiple competing actions.

Personalize Offers and Segments for Effective Direct Mail

Personalization increases response rates by making mail more relevant to each recipient. According to research, even basic personalization can lift response rates by up to 44%.

1. Leverage Data Insights for Tailored Messaging

Personalize at different levels based on your data:

  • Basic: Include the person's name and basic information
  • Intermediate: Reference past purchases or account information
  • Advanced: Customize offers based on behavior patterns and preferences

For example, an online retailer might show different products based on what categories a customer has browsed before. A bank might feature different loan offers based on a customer's financial profile.

Lob enables variable data printing that changes text, images, and offers for each recipient automatically.

2. Time Your Sends to Key Customer Milestones

Send mail based on specific triggers or events:

  • Birthday or anniversary offers
  • Post-purchase follow-ups
  • Reactivation campaigns for inactive customers
  • Seasonal promotions aligned with buying patterns

Triggered mail typically performs better because it arrives when it's most relevant to the recipient. For example, a reminder about reordering a product that's about to run out is more timely than a generic promotion.

Optimize Direct Mail Campaigns With Testing and Measurement

Testing helps you learn what works best with your audience. By comparing different versions, you can improve results over time.

1. Run A/B Tests on Offers and Formats

Test one element at a time to see what affects performance:

  • What to test: Offers, headlines, images, formats, or CTAs
  • How to test: Send version A to half your list and version B to the other half
  • When to decide: Wait until you have enough responses for statistical significance

Common testing mistakes include changing too many elements at once or drawing conclusions from too small a sample size.

2. Track Conversions and Iterate Continuously

Measure results to understand what's working:

  • Response rate: Percentage of recipients who take any action
  • Conversion rate: Percentage who complete your desired goal
  • Cost per acquisition: Total campaign cost divided by new customers gained
  • ROI: Net profit compared to campaign investment

Use tracking methods like unique codes, personalized URLs, or dedicated phone numbers to connect mail pieces to specific responses.

Lob's analytics tools help you see delivery confirmation and track response patterns in real time.

Integrate Direct Mail Marketing Tips With Digital Channels

Direct mail works even better when combined with digital marketing. Each channel reinforces the others for a stronger overall impact.

Effective channel pairings include:

  • Direct mail + email: Send a physical piece first, then follow up with email reminders
  • Direct mail + social media: Use similar messaging and visuals across both channels
  • Direct mail + retargeting ads: Show online ads to people who've received your mail

This table shows how different channels complement direct mail:

Channel How It Works With Direct Mail
Email Reinforces mail messages and provides quick response options
Social Media Extends campaign visibility with matching visual elements
Retargeting Ads Reminds recipients about offers they received in the mail
SMS Provides timely alerts about mail offers or deadlines


Consistent messaging across channels creates a unified experience that improves overall campaign performance.

Automate Campaigns to Improve Direct Mail Optimization

Automation turns direct mail from a slow, manual process into a responsive marketing channel that works at digital speed.

1. Trigger Sends With CRM or MAP Data

Set up automated mail based on customer actions or events:

  • When someone abandons an online shopping cart
  • After a customer reaches a loyalty milestone
  • When a subscription is about to expire
  • Following a significant life event (moving, birthday)

These triggers connect to your customer database or marketing platform, sending mail automatically when conditions are met.

Lob's API connects with systems like Salesforce, HubSpot, and Marketo to enable these automated workflows.

2. Scale Production With Real-Time Workflows

Automation streamlines the entire mail process:

  • Reduced time-to-mailbox: Eliminates delays between data triggers and mail production
  • Fewer errors: Removes manual data entry and file handling mistakes
  • Consistent quality: Ensures every piece follows the same standards
  • Easy scaling: Handles campaigns of any size without workflow bottlenecks

Lob's Print Delivery Network manages production across certified print partners nationwide, optimizing for speed and delivery.

Frequently Asked Questions About Targeted Direct Mail

How much does a targeted direct mail campaign typically cost?

A targeted direct mail campaign costs vary based on design complexity, printing specifications, mailing list quality, and postage rates. While targeted campaigns may have higher upfront costs than mass mailings due to data and personalization requirements, they typically deliver better ROI because they reach more relevant audiences.

Well-targeted direct mail campaigns typically achieve response rates between 5% and 9%, compared to around 1% for untargeted mailings. Personalization, relevant offers, and clear calls-to-action significantly impact these rates, as does the quality of your mailing list and the timing of your campaign.

How can I measure the ROI of my direct mail campaigns?

Measure direct mail ROI by tracking responses through unique codes, personalized URLs (PURLs), QR codes, or dedicated phone numbers that connect each mailpiece to specific customer actions. Calculate ROI by comparing campaign costs against the revenue generated from these tracked responses, including both immediate conversions and longer-term customer value.

How do I ensure my direct mail complies with privacy regulations?

Ensure compliance by maintaining clear opt-out mechanisms for recipients, handling personal data according to relevant regulations (like GDPR or CCPA), using secure systems for storing mailing list information, and staying current with postal regulations.
