Letterbox Advertising

Direct mail offers a 20% higher motivation response than digital marketing. And 47% of customers visit a store after receiving a direct mailer, making the campaign successful. Most marketers struggle to get such incredible results with other marketing channels, making letterbox marketing more popular than ever!

But what is letterbox advertising, and how can you ensure its success?

This blog discusses the benefits of Canada Post door-to-door mailing and the steps to launch an effective campaign!

Let us start! 

Below, we have enlisted the top six ways you can ensure your letterbox marketing campaign’s success:

#1 Segment Your Target Audience

Avoid using the one-size-fits-all approach for letterbox marketing strategies because every customer reacts to your messages differently. Some might appreciate a 5% discount and rush to your store to make a purchase. Others might only respond to more compelling offers, like a 50% cashback offer or free coupons.

Similarly, people living in different locations respond to direct letterbox marketing mailers in unexpected ways. It depends on several factors, like accessibility to your store, competitors’ offers, preferences, buying habits, etc. 

The best method to work with these differences is to use segmented mailing lists for your letterbox advertising campaigns. Use geo-demographics and customer data in your system to compile a targeted list of your prospects. 

If you need help, PostGrid offers custom mailing lists based on

• Location. 
• Online buying habits. 
• New movers and old residents. 
• Age and gender. 
• Annual income. 
• The number of children. 
• Marital status, etc. 

Segmenting your mailing lists allows you to personalize your letterbox marketing messages and tailor your offers according to the customers’ needs. Instead of sending out generic mailers and waiting for prospects to want your products or services, take charge and reach them with what they require!

#2 Focus On Your Artwork

Nothing is more unprofessional than sending mailbox advertising items with a bad design. Your artwork must fit your brand’s marketing objectives and represent your company’s mission. 

Try using colours similar to your logo to increase brand recognition rates. You may also include your tagline (if you have one) on all items to make your audience remember you across all channels. 

Here are some of the best design tips you can employ for your letterbox advertising artwork:

• Print relevant images with vivid colours to make your message pop. People tend to pay more attention to visuals than written texts! They also make readers grasp the content more precisely, making it worth using custom imagery for your mailers. 
• Use enough negative space to make every aspect of your direct mail design visible. Your letterbox marketing offers or CTAs must not get lost among a pool of sentences and graphics. Do not add too many features and make your design messy. 
• Make your envelopes look unique and appealing. Many marketers put a lot of effort into their letterbox advertising artwork but forget to make their envelopes eye-catching. It is now time to ditch the boring white outer covers and add a pinch of creativity. Some ideas include using different colours, adding one-line teasers, and employing embossed finishing techniques to attract readers. 

#3 Use a Headline That Sells

Lousy headlines impact your audience negatively and make them not want to read your message. But luckily, a well-curated headline has the opposite effect and can drive responses dramatically!

Your letterbox marketing items should have a catchy headline that

• Offer a solution to the reader’s problem. 
• Present an exciting proposal. 
• Provide the reader with compelling discounts or other offers.
• Create demand for your product or service. 

Try to keep it short and sweet so people can remember your campaign for a long time. But remember that it should ignite your audience’s interest and make them want to respond to your letterbox advertising message!

#4 Be Memorable 

Though direct letterbox marketing faces less competition, try putting extra effort to stand out from the other mail items your prospect might receive! Customers remember shocking, relatable, or humorous messages better—so add these factors to your content to improve responses. 

Tell your brand’s story and show how you evolved over the months or years. People relate to experiences and not features. Limit using technicalities and explain how your products or services can benefit the users. 

Other ways to make your mailbox advertising campaign memorable include using oversized envelopes, glossy finishing, riddles, contests, etc. You can also ask your audience to share pictures of their mail items on social media with a unique hashtag to increase engagement. Offer them a small offer to do so or announce winners at the end of the campaigns. 

#5 Include an Upfront Call to Action

Your direct mail recipients must know what to do next after they read your letterbox advertising message and wish to respond. Hence, include a straightforward CTA that guides them further and helps you generate responses. 

Here are some examples of the CTAs you may use:

• Go to our website now and redeem your free points. 
• Get a 20% discount on your first purchase before 10 November 2025. 
• Call us or drop us an email to get a freebie.
