Two weeks ago, we shared a couple of reasons why it is so important to test direct mail formats. Guess what? There are even more reasons! Continuing onwards… 

Reason #3: You can achieve different marketing goals.  

Recently, we discussed how various formats resonate with different consumers. It’s also important to be mindful of your marketing goals. Direct mail helps facilitate customer acquisition, retention, market research, and increases response rates. If your marketing goal is… 

Customer acquisition:

POSTCARDS are a cost-effective way to reach a vast audience quickly. They are attention grabbing due to their size and ideal for promotions and offers.  

PERSONALIZED LETTERS facilitate a more personal connection. You will not only connect with the customer, but these are an effective way to show / explain complex offers (products or services) in more detail.  

CATALOGS showcase a wide range of products and services while personalizing and targeting your audience. Essentially, catalogs hit what postcards and letters do, and more!  

Customer retention:

SPECIAL OFFERS make a difference. Whether you use a postcard or a letter, it is important to create exclusivity with special discounts, early access (sneak peek or VIP access), limited-time promotions, and milestone celebrations.  

NEWSLETTERS serve as consistent touch points; they will help you to stay top-of-mind with customers.  

PACKAGE INSERTS pique interest. Whether you include a ‘thank you’ from your CEO or Founder, or offer a small gift or discount, this will show your customer you value their business.  

EXCLUSIVE LOYALTY PROGRAM MAILERS highlight the benefits of your loyalty program and encourage participation (Guess what? We can help you with this! Reach out here).  

Market research:

SELF-MAILERS can help. Combine a brochure / leaflet format with mailing information.  

EVERY DOOR DIRECT MAIL (EDDM) is an efficient option that delivers mail to every address on the carrier route, without requiring individual addresses. (Plus, there is a reduction in postage!). 

PERSONALIZED LETTERS allow you to connect with customers via a unique letter, and drive to your website – facilitating a multi-channel connection – with an incentive to complete a customer satisfaction survey.    

Increased response rates:

LETTERS IN ENVELOPES drive interest. The curiosity or perceived importance of a letter in an envelope can lead to a higher engagement and response rate.  

POSTCARDS are useful for grabbing attention and are an excellent format to test out different creative and offers.  

Reason #4: You can make branding (or re-branding!) a priority. 

Direct mail can increase recognition and visibility of the brand to a specific audience.  

From tangibility to creative messaging and personalization, this is a powerful channel for branding. With direct mail, you can offer consistent messaging that reinforces brand identity and helps to establish trust with consumers.  

Reason #5: You can optimize your multi-channel approach.  

Direct mail can complement digital marketing efforts, creating a cohesive and seamless brand experience across platforms. For example, sending a direct mail piece can encourage recipients to visit a website or engage on social media. Up for going one step further? Change up your formats to test performance – whether it’s different physical formats or new digital platforms, testing is always recommended.  

In fact, testing different formats – for both digital and offline marketing – can lead to cost-savings, further reach, new customers and more.

Over the years, “direct mail” has become an umbrella term for any piece that’s in the mail. Did you know that there are endless possibilities of formats? That said, there are specific formats most effective for achieving different goals.  

With consumer behavior constantly changing; new audiences on the horizon; and the hot topic of attribution, there are so many reasons it’s important to test different direct mail formats. We promise (yes, promise!) that it’ll be worth it… and will ultimately help your bottom line.  

Here’s why you should test different formats…. 

Reason #1: You can reach different types of consumers & connect with them more effectively. 

___

Baby Boomers: Prefer Catalogs, Self Mailers, Shared Mail, Insert Media / Package Inserts 

Creative Tips:

• Legibility: Use large, clear fonts and high contrast (e.g., dark text on light backgrounds). 
• Simplicity: Organize information logically. While this generation likes information, you do not want it to be overwhelming.
• Trust: Include testimonials, reviews, certifications or badges that build credibility. 
• Call to Action (CTA): Firstly, make sure you have one! Secondly, make it prominent, clear, and actionable (e.g., “Call now!” or “Visit us online for more details”). 

___

Gen X: Prefer Personalized letters, brochures and newsletters featuring loyalty programs, interactive mail (QR codes / personalized links), mini catalogs. 

Creative Tips:

• Straightforward & Direct Messaging: This generation values efficiency and transparency. Avoid unnecessary fluff or overcomplicated language. 
• BeProfessional but Approachable: Gen X responds well to brands that appear reliable and trustworthy, yet personable and genuine. 
• Clear and Actionable CTAs: Include a call to action that makes it easy to take the next step (e.g., “Call to schedule,” “Visit us online,” or “Shop now”). 
• Tech-Friendly: Include digital components, like QR codes or personalized URLs, but make sure they’re easy to use and provide clear value. 

___

Millennials: Prefer Postcards with Social Proof or User-Generated Content, interactive mail (QR codes / personalized links), mini catalogs or look books, event invitations (experience-focused), newsletters featuring content and offers. 

Creative Tips:

• Minimalistic Design: Focus on clean lines, only delivering necessary information, imagery and creative elements for necessity with ample white space, and modern typography. 
• Visual Appeal: Drawn to eye-catching, high-quality imagery that feel authentic. 
• Mobile-Friendliness: If incorporating QR codes or personalized links, ensure the digital experience is mobile-optimized. 
• Sustainability: Highlight any eco-conscious initiatives your brand is involved in, as Millennials often prefer brands that are environmentally responsible. 

___

Gen Z: Prefer Interactive Mail (QR Codes, Augmented Reality, Personalized URLs), Eco-Friendly and Sustainable Direct Mail, postcards, event invitations (exclusive experiences and collaborations), Gamified Direct Mail (Scratch-Offs, Contests), Personalized Merchandise Offers (Customized Products), Limited Time Off and flash sales, User-Generated Content or Social Media Integration. 

Creative Tips:

• Authenticity: Gen Z values honesty and authenticity in brands. Avoid overly polished or “salesy” language, and focus on being real. 
• Visuals Matter: Use bold, high-quality visuals, and make sure the design is on-trend and aesthetically appealing.  
• Mobile Optimization: Since Gen Z is heavily mobile-first, ensure any digital component (QR code, URL, AR experience) works smoothly on smartphones. 
• Short & Sweet: Gen Z has a shorter attention span, so keep your messaging concise and impactful. A powerful message will resonate.   

Reason #2… You can capture consumers’ attention that are suffering from digital fatigue.  

From a lack of variety; to repetitive messaging; to disjointed creative; to poor targeting, digital fatigue is real! We don’t want you to be wasting any marketing dollars on ineffective campaigns. More than 60% of individuals are reportedly overwhelmed by digital marketing tactics.  

Mitigate digital fatigue with personalized content, variety in formats, a thoughtful contact strategy, audience segmentation, and opt-in capabilities.  

Forty-two percent of consumers recently reported an increased interest in direct mail and because of that, 75% of marketers have reallocated their marketing budget into direct mail.  

Switching up your mediums and formats (along with creative!) within channels is extremely important. Direct mail drives response because it’s different; because it’s personal; because it’s tangible… among many other reasons.  

In fact, we’ll take you through even more reasons next week about why it’s important to test different formats, especially in direct mail!
