Direct mail still plays an important role in how you reach and convert audiences. You can use it to share offers, updates, and reminders in a format that stands out from crowded inboxes and feeds.
When you treat direct mail like a performance channel, not a one-off campaign, it becomes measurable, repeatable, and easier to scale. The right practices help you send fewer wasted pieces, reach the right people, and prove impact back to the business.
This guide walks through the key elements of direct mail best practices. Each section covers a core area, from maintaining your mailing list to integrating direct mail with your digital strategy. By using these techniques, you can create direct mail that is accurate, relevant, and easy to measure.
Your mailing list is the foundation of every direct mail campaign. When addresses are accurate and current, your mail actually reaches the people you want to reach and your response data becomes more trustworthy.
Outdated or incomplete addresses lead to undeliverable mail, wasted budget, and noisy data. If mail never makes it to the mailbox, you cannot tell whether your offer, creative, or timing was the issue.
The solution is to treat address quality as an always-on process. Before you send, validate and standardize addresses using tools like address verification. This helps correct typos, format addresses to postal standards, and flag undeliverable records so you can fix or remove them.
A clean list reduces postal costs, improves delivery rates, and gives you reliable performance data you can trust. For a deeper dive into list building and targeting, see our guide to targeted direct mail best practices.
Effective direct mail design combines visual clarity with a focused message and a clear next step. Every element of the piece should help the recipient understand what you are offering and why they should act.
Start by deciding what you want people to notice first. Then use size, placement, and whitespace to make that element stand out.
Choose high-quality images that support your message and appeal to your target audience. Maintain consistent branding across all materials using the same fonts, colors, and design elements. This consistency helps recipients recognize your brand and builds trust over time.
If you want a shortcut, you can start with proven layouts in Lob’s Direct Mail Template Gallery, then customize the copy, imagery, and branding for your audience.
Your copy should be direct and specific. Focus on the outcome you are delivering rather than a list of features.
Close with a clear call to action. Tell people exactly what to do next, whether that is visiting a URL, scanning a QR code, or calling a dedicated number. For more ideas, explore our article on best practices for direct mail creative.
Personalization turns direct mail from a generic message into something that feels relevant and timely. When people see offers that match their needs, they are more likely to respond.
Begin by grouping your audience into meaningful segments. These might include:
Each segment can receive different offers, imagery, or messaging that speaks more directly to their situation.
Use the data you already have in your CRM or customer database to personalize your content. This might include:
For deeper personalization strategies, you can explore resources like our content on personalization in direct mail, which includes proven response-rate results and examples of what works at scale.
Personalized URLs (PURLs) and QR codes make your mail interactive and trackable. Each recipient gets a unique link or code that sends them to a tailored landing page or offer. That lets you:
You can learn more about how to use PURLs for measurement and attribution in our guide on PURL campaign tracking.
Even strong campaigns have room to improve. Testing gives you a structured way to find what really moves the needle with your audience.
The most useful tests are simple and specific. Choose one element to test at a time so you can clearly see what changed.
Common variables include:
Split similar audiences into test groups so the results reflect the creative differences, not the list.
Use unique promo codes, phone numbers, PURLs, or QR codes to track responses by variant. Look beyond basic response rate and measure:

Use what you learn to update future campaigns. Over time, even small improvements in response and conversion compound into meaningful gains.
Direct mail works best when it is part of a coordinated, multi-channel strategy. By combining mail with email, paid media, and onsite experiences, you create more touchpoints and more consistent messaging.
Here are a few practical ways to connect your channels:
When you plan campaigns, think about where direct mail fits in the sequence and how it can support your digital efforts. For more on this, read our article on how automated direct mail transforms modern marketing campaigns.

The goal is to make direct mail feel as easy and flexible as sending an email campaign.
To improve your direct mail program, you need clear, consistent ways to measure performance and capture feedback from the people you mail.
At a minimum, you should monitor:
You can also track engagement at a more granular level using QR codes, PURLs, unique phone numbers, and coupon codes. For a deeper breakdown of measurement strategies, see our content on the best metrics to measure direct mail effectiveness.
Quantitative data is important, but qualitative feedback matters too. Ask customers how they heard about you, include short surveys in follow-up emails, and review comments that come through customer support channels.
Look for patterns in what people respond to, what confuses them, and what they ignore. Use that insight to refine your offers, creative, and targeting.
Lob helps you connect campaign data and delivery events with your existing analytics, so direct mail performance becomes part of the same reporting you already use for digital channels.
Strong direct mail campaigns are not built on guesswork. They follow a clear set of best practices that you can apply again and again.
Start with clean, verified address data so your mail reaches the right people. Design clear, focused pieces that highlight the benefits and spell out the next step. Personalize your content where it makes sense, and connect your mail to digital journeys through PURLs, QR codes, and triggered follow-ups.
Most importantly, keep testing, measuring, and adjusting. Direct mail becomes more powerful when you treat it as an iterative, data-driven channel rather than a one-time send.
If you want to go deeper, Lob’s direct mail fundamentals and resource center offer more examples, checklists, and guides to support your program.
