Planning your next direct mail campaign and trying to choose between postcards and envelopes? Each format offers specific advantages for different marketing goals, budgets, and message types. Let’s take a look at when and where each format makes sense.

What Are the Main Differences Between Postcards and Envelopes?

Postcards are single-piece mailers with immediate visibility. There is no envelope to open, so your message and CTA get seen right away. Envelopes, on the other hand, allow you to include multiple components and provide more information (such as letters, brochures, and reply cards). Still, recipients must open them before any of that gets seen.

Here's something marketers instinctively know but customers keep confirming: Personalized communications get more attention than generic ones. Whether you're sending bills, statements, promotional offers, or marketing campaigns, personalization consistently drives engagement. Survey data proves it yet again.

What Customers Say About Transactional Mail

Trade shows offer invaluable opportunities to connect with prospects, strengthen relationships with existing clients, and showcase your brand to a target audience. However, success doesn't happen by chance. It requires careful planning and strategic use of marketing tools before, during, and after the event. Here are seven essential elements that will help you maximize your trade show impact.

1. The Heavy Hitter: Direct Mail

Your packaging is often the first physical touchpoint a customer has with your brand. It's also increasingly a statement about your values. Today's consumers don't just want great products. They want to feel good about their purchases. Eco-friendly packaging that stands out isn't just responsible marketing, it's innovative business!

Sustainability Sells

In a world drowning in digital noise, print isn't just surviving. It's thriving. As we move into 2026, savvy marketers are rediscovering what neuroscience has been telling us all along: physical materials make a lasting impression that pixels simply can't match.

The Science of Staying Power

How can you boost your direct mail results on a budget? It doesn't have to be complicated. Sometimes the most straightforward steps have the most significant impact. Here are five tips for simple, inexpensive changes that can lead to substantial results.

1. Be relevant, not fancy.

Do you know what your customers think about you? If the answer is yes, what is that based on? Gut feeling? Or is there data behind your answer? Whether you use print, email, or focus groups, it’s essential to find out for sure.

The reason isn’t academic. Research shows a significant gap between how companies perceive their performance with customers and how they actually perform. According to Bain & Company, 80% of companies think they provide superior customer service, but only 8% of their customers think they receive it.

Ever wondered what separates a forgettable ad from a campaign that wins industry acclaim? It's rarely about flashy production or massive budgets. The real magic happens when marketers deeply understand their audience and deliver content that genuinely resonates.

We analyzed several years' worth of award-winning print ads to identify common themes. Here's what we found:

Marketing success isn't just about generating leads. It's about strategically guiding customers through each phase of the buyer's journey. This systematic approach, known as lead nurturing, involves presenting the correct information at the time your prospects need it most.

When it comes to lead nurturing, one of your most potent tools is content marketing. According to BPM Online, which offers a platform for process-driven CRM, B2B marketers overall allocate 28% of their total marketing budgets to content marketing. However, companies that achieve the best returns from this channel tend to allocate up to 46% of their budgets to content marketing.

You're preparing to launch your next direct mail campaign. You've updated your mailing list and identified your target variables, but what about your messaging? If you've been targeting the same customer base for a while, it's critical to regularly evaluate your approach to prevent things from going stale.

Here are five areas where a refresh might be in order:

Want to capture your audience's interest and drive purchases? Use psychology! One helpful model is Dr. Robert Cialdini's framework for persuasive marketing. His six concepts—limited availability, mutual exchange, credibility, peer validation, connection, and commitment—can be enormously helpful for improving outcomes and prompting swift customer action.

Here's an overview of each principle:

Design trends change. Fonts change. Even the way people browse catalogs and ads shifts over the years. However, some marketing techniques remain timeless. They strike chords so profoundly rooted in human psychology that they deliver results decade after decade.

Want proof? Look no further than the grand controls in the Who’s Mailing What! database. “Grand controls” are direct mail campaigns that have run for years (sometimes decades) because they continue to work. Studying them reveals which offers and techniques consistently resonate with audiences.

Every buyer is unique. Yet, certain principles of human behavior apply to nearly everyone. Understanding these principles can help you guide your direct mail and digital marketing strategies more effectively.

Ross Kimbarovsky, founder and CEO at Crowdspring, an online marketplace for crowdsourced creative services, has synthesized these principles into five helpful marketing hacks that can transform your offers from “I’ll get to it later” to “I need to act on this right now!”

Consumers prefer buying from brands they trust, and often, the first point of contact with your brand is your company logo. This makes it even more important to have a logo that fosters confidence. Every time customers see your logo, whether it’s on a postcard or a piece of marketing collateral, it has the power to strengthen or weaken their trust. You want it to enhance their confidence, but what makes a logo trustworthy?

Let’s take a look:

In today’s “always on” digital environment, the world is at our fingertips. Open, click, view, buy, comment, download. Anything you want. It’s all right there. Even so, book readership is on the rise, and a recent Association of National Advertisers study found that direct mail delivers a higher return on investment (ROI) than any digital channel. Why? Because “digital everything, everywhere” gets old sometimes.

Let’s look at four reasons people still embrace the value and allure of print.

Customer values and behavior are constantly changing. When this occurs, do your print marketing strategies track with them? The formats you choose, the messaging you write, and the layouts you create are all impacted by consumer trends.

Let's look at four trends that are popular right now:

Want a strong, recognizable brand identity? Creative and engaging marketing pieces are essential, but if those designs aren’t consistent across channels, your brand might be memorable, but not necessarily perceived as professional. That’s why it’s crucial to maintain consistent branding across all channels. Consistency keeps your business top of mind, fosters trust, and reinforces your credibility.

How can you ensure your brand looks cohesive, regardless of which channel(s) customers use to engage with you? Here are five ideas to get started:

When designing a printed piece, how much attention do you pay to the grain of the paper? This is particularly important for pieces that require crisp, clean folds. Aligning your design with the paper grain can make a significant difference in the final result.

What is paper grain? It refers to the direction in which the paper fibers are aligned during the papermaking process. This alignment affects the paper's strength, flexibility, and ability to fold smoothly or resist bending.

Sustainability has become a core value for many consumers and businesses. However, as brands rush to position themselves as environmentally responsible, a growing challenge has emerged: greenwashing.

What exactly is greenwashing? Greenwashing is the practice of making misleading, exaggerated, or unsubstantiated claims about a company's environmental practices or a product's eco-friendliness. Greenwashing can take many forms, from buzzwords like "eco-friendly" and "natural" on product packaging (with no supporting evidence) to images of greenery and leaves in a direct mail piece that implies sustainability without proof.

You've invested time, money, and effort into winning great customers. You have ongoing marketing programs to help keep those relationships strong. But what happens when customers stop buying anyway? Instead of watching them go, reignite their interest instead. Direct mail is one of your most powerful tools for doing it.

Here's why direct mail is uniquely positioned to bring lapsed customers back:
