You have multiple marketing channels to incorporate for your upsell and cross-sell techniques. But which one is the best and can suit your motives ideally?

Here is an example of a cross-selling campaign to help you understand how the process works:

Imagine you visit an online store selling eye spectacles for men, women, and kids. You check out the latest trends and pick a few options! 

After putting in enough thought, time, and attention, you finally choose the specs having the best color and style. 

When you move to the checkout page, the business pulls up a cross-selling campaign to make you pay extra. But wait! Let us explore the deal and decide whether it is worth it!

The transaction page asks you to add UV coating and anti-glare lenses for an additional charge. You think that the features are helpful and add them to your cart. Next, there is a pop-up cross-selling campaign ad saying you can include a 1-year membership for only $10. 

So you keep adding things and get a whole package of services, from better quality specs to a year-long membership! The business also benefits from the extra money you pay for these upgrades. 

Now, let us talk about upselling- that requires different strategies than a cross-selling campaign for various reasons. You can execute an upselling program simultaneously with your marketing campaigns or launch one at the end. Either way, do not overdo it and maintain a balance between persuading and compelling clients to purchase something. 

Here is a use case of one of our clients in the retail sector who launched effective and result-driving upselling campaigns. The business operates a large store selling home appliances online. And they were not satisfied with their cross-sell and upsell campaigns in recent months. 

Thus, they employed PostGrid’s direct mail services to create, print, and ship eye-catching upsell mailers to their target audience. This upselling and cross-selling campaign convinced customers to visit the client’s website and make a purchase. Moreover, the direct mailing postcards consisted of a list of several higher-priced items for customers to ditch their original preferences and buy something more extravagant. 

The result was phenomenal- a 25% conversion ratio in only one month! 

This upselling and cross-selling campaign helped the client recover its marketing costs and generate a massive ROI!

As said before, businesses can use a broad range of offline and online marketing forms. So why choose direct mail for a cross-selling campaign for your company?

According to a study, customers say they are likely to respond to 32% of all direct mail marketing items. With an average response rate of 5 to 9%, it is helpful to marketers during all stages of their advertising funnels. 

While planning cross-sells and upsell campaigns, you must consider the following factors:

• Select a trustworthy communication medium. 
• The channel must be around for a long time to create confidence among people. 
• Its open and read rates must be more than 90% to make your cross-selling campaign successful. 
• It should establish personal connections. 

Direct mail meets all these requirements, making it suitable for cross-sell and upsell campaigns to drive more revenue! But it can feel overwhelming to plan a direct mailing program because you must take care of a hundred things for it to become successful!

You can incorporate several methods to create a buzz for your cross-selling campaign and generate maximum results.

We have enlisted some of these ways below:

Use Postcards With Large Background Images

Your direct mail postcards must have a few words and sentences, but the primary highlight must be the imagery! Choose relevant, bright-colored images that add meaning to your mailers and communicate with your audience 1:1.

Employing postcards as part of your cross-selling campaign allows you to keep costs low and combine direct mail with other channels. For instance, you could launch a simultaneous email drip marketing campaign to reinstate your message. Or you can run media location-based cross-selling campaign ads on social media.

Try using the same artwork for all channels to leave a better influence and create brand recognition.

Exciting Offers

Your offer must add value to your postcards and answer WIIFM (What’s In It For Me) for prospective customers. Offers help give your customers a reason to respond to your cross-sell and upsell campaigns confidently and speedily!

You can include sentences like

• Buy one, get one free
• Get a 20% flat discount
• Use the code below to receive 100 free points in your account
• Get 10% cashback on your next purchase, etc.

Most cross-selling campaign readers skip the message to read the offer. Make it worth their time and use it as an excellent opportunity to convert as many leads as possible!

Maps to the Nearest Store

If you operate offline stores, mailing postcards helps redirect prospects from their doorsteps to you. Try including accurate maps in your cross-selling campaign postcards to guide your readers. Keep looking at the business postcard ideas and examples to gain more knowledge on it and grow.

Make your maps custom and compact to fit in the postcard size. Alternatively, you can include a QR code that takes customers from their location to your nearby store. It takes less space and adds a digital touch to your offline cross-sell and upsell campaigns to appeal to people of all ages.

Straightforward CTAs

Use CTAs that are upfront and easy to complete instead of those that puzzle customers. Here are some examples of cross-selling campaign CTAs that work:

• Scan the QR code below to see your latest Holiday offers.
• Visit the link and checkout with a 10% discount.
• Take this postcard and visit our store today for a 5% cashback offer.

Restrict your upselling and cross-selling campaign CTAs to one line to create a positive impact and persuade customers to act faster. Leave enough negative space around the CTA so that readers see them in one look and contemplate completing them instantly.

PostGrid’s direct mailing solutions for cross-selling and upsell campaigns enable businesses to create productive postcards. You don’t need to stress over using the correct CTAs and tracking responses because PostGrid does the extra legwork on your behalf!

Appealing Headlines

Your direct mail headline is at the top or center of the artwork, making it highly visible to everyone. Remember that postcard don’t require envelopes, so all your readers must do is flip over the card and read your headlines.

Try using powerful words like “you,’ “us,” “free,” “offer,” “discount,” and “deadline” to divert your audience’s attention to your cross-selling campaign and drive responses.

You may also include the CTA or offer line as the headline to not waste time and jump straight to your motive!
