15 Postcard Marketing Mistakes

Postcard marketing is the least expensive form of direct mail marketing. Make your postcard marketing campaign successful by avoiding these 15 common mistakes often seen in direct mail campaigns.

Marketing with postcards has long been an affordable way for many types of businesses to reach their customers. My veterinarian, for instance, always sends postcards with colorful, entertaining cartoon illustrations of cats, dogs, and other assorted animals. The mailings are irresistible and, of course, also contain the customary reminder on the print side that one of our dogs is due for a check-up.

They are also very effective; we haven’t missed scheduling an appointment yet.

Why a Postcard Marketing Campaign Works

Many businesses already know what my veterinarian knows: postcard marketing can be irresistible and a great way to get someone’s attention. Direct mail postcards are a versatile and cost-effective way to reach your target audience without the need for envelopes. Postcards are also a great way to:

  • Generate sales leads.
  • Promote special offers or coupons.
  • Introduce a new product or service.
  • Keep in touch with existing customers.
  • Drive traffic to a website.
  • Test several messages and offers.

Postcards get read, and the reason is simple:

Mail in envelopes has to be opened first to be read. People often look at just the envelope, decide they’re not interested, and out it goes. In contrast, a postcard is already “opened” and ready to read. At the very least, the message will be seen — no matter how speedily — by the recipient.

Postcards are the least expensive form of direct mail today, are easy to create, and typically generate a high rate of response.

When you combine all these factors, it’s no wonder then that businesses today use postcards as a tremendously powerful marketing tool.

Postcard Marketing Mistakes to Avoid

It is, however, important to avoid some common mistakes businesspeople make in postcard marketing campaigns. Doing so can mean the difference between success and failure.

1: Not Setting a Goal for Your Postcard Mailing

A postcard mailer needs to have a specific goal. The goal might be to get existing customers to come back, attract new customers to come to your location, or develop sales leads. You need to decide on that goal when you create the mailing so you can choose the right message and call to action to include on the card and best mailing list for the campaign.

2: Not Targeting the Best Prospects

How much of a response do you think the Omaha Steaks company would get if they sent marketing postcards to the subscriber list of the Vegetarian Times? Probably zip to nil, unless there’s a closet carnivore among the ranks.

Mailing to the wrong list is an expensive postcard mailing mistake. Sending mail to people who aren’t likely to want or use your product or service wastes the cost of the printed card and stamp. In most cases, your own mailing list (i.e., a list of customers and prospects who have identified themselves to you) is the best list.

If you don’t have an in-house list, you can develop your own or get a rented one, but be sure to go to a list broker and be clear about your target market. For a fee, you can rent subscriber lists of specialized publications and newsletters read by prospects in your targeted market.

3: Omitting a Call to Action

When people are busy or preoccupied, they may see something on a postcard that piques their interest, but if they don’t see clear instructions on what to do next, they’ll put the postcard aside to read “later” or just put it directly into the recycle bin. Solve the problem by having a clear call to action telling the recipient what you want them to do and how to do it. “Call today,” “Order by [date] and save 20%,” and “Present this card for a free gift” are examples of calls to action that tell direct mail prospects what to do.

4: Sending Just One Mailing

Another big postcard marketing mistake is sending just a single mailing instead of planning for successful direct mail campaigns with multiple mailings to the same list. Consistent repetitive mailings are exceedingly more effective than a one-time, shot-in-the-dark mailing. When someone sees your company name over and over again, it builds credibility and familiarity. Although it may take a number of contacts with a customer before it leads to a sale, the eventual increase in revenue usually far offsets the small cost of postcard printing.

5: Sending a Postcard that Isn’t Personable

You want your postcards to look professional but also contain an affable message that produces a pleasant emotional reaction from readers. Postcards that contain a brief personal message generate significantly more replies than those that read like a cold, formal ad.

6: Mailing Missteps

Avoid using indicia (imprinted postage) when possible, i.e., for small mailings. People associate it with junk mail. A first-class stamp costs a little more per card but looks friendlier and produces more replies. In addition, you get all the benefits of first-class mail, including a “return to sender” if the address is no longer valid. This is a great way to maintain and update mailing lists.

Consider the various formats and dimensions available when mailing postcards to ensure they stand out and are effective.

Pay attention also to postcard arrival dates. Monday, Friday, and holiday-time arrivals have been proven to be less effective; Tuesday and Wednesday arrivals get the best results because the volume of mail is generally lighter on those days. Check with your postal service if you’re unsure how to gauge postcard arrivals, especially if you’re mailing out of state.

7: Spending Too Much on Postcard Printing

Today, a business does not need to spend a bundle on postcard printing. You can print an attractive postcard on your laser or inkjet printer for just pennies a card plus the cost of ink. For larger mailings, professional printers charge considerably less per card as the number of postcards increases, and it may actually cost less than doing it yourself.

Office supply stores have ready-made perforated postcard sheets, including those with top-of-the-line coated postcard paper.

8: Using Postcards as a Sales Pitch

Don’t try to close sales directly from your postcard. There’s not enough space to provide all the information needed to do so. Use the postcard instead to grab the reader’s attention and then lead them to the next step that can close a sale, such as visiting your sales webpage, coming to a grand opening, or using a coupon.

9: Not Enough Attention to the Headline, Image, or Message

A short, attention-getting, and compelling headline will bring about 20 times the response to a postcard than one with a bad headline or none at all. Combine the headline with the image side, and this will then guide the reader to the message side. The image should be easily comprehended, attractive, and brightly colored. Be sure that the message clearly expresses what you’re promoting; otherwise, your efforts may be fruitless.

10: Not Keeping the Message Simple

Think brevity. Your postcard will probably garner a one to two-second initial glance, so don’t weigh down your chances of success with clever dissertations, jargon, or a laundry list of everything you offer. Use short, complete sentences with well-chosen plain language and bullet points that will get the attention of the reader. Promote no more than one key thing per card. Convey just what is important and what the reader should do next.

Mail postcards are particularly effective because they deliver concise messages that are easy for recipients to understand quickly.

11: Failure to Provide Contact Information

It sounds like common sense to provide a telephone, cell, and fax number, as well as an email and return address, but too many times, contact information is forgotten on business postcards. Be sure to include your company name as well.

Using Every Door Direct Mail can help ensure that your contact information reaches every residential address in your targeted local area.

12: Failure to Proofread

A spelling, punctuation, or typographical error reflects poorly on the sender, especially if the sender is a business. Even the best writers proofread their works, sometimes over and over again, before sending them to print. Whether or not you write or print the postcard copy yourself, it must be proofread. A good way to do this is to read it aloud. It’s also beneficial to have someone else review it; another person will often catch things that you may overlook.

13: Crafting a Postcard That Isn’t Visually Appealing

One of the most common mistakes in postcard marketing is creating a postcard that isn’t visually appealing. A lackluster design can lead to low engagement and poor conversion rates. Your postcard needs to stand out in the recipient’s mailbox and grab their attention immediately.

To avoid this mistake, follow these tips:

  • Use High-Quality Images: Ensure that the images you use are high-resolution and relevant to your message. Blurry or irrelevant images can detract from your postcard’s appeal.
  • Choose Readable Fonts: Select fonts that are easy to read and consistent throughout the postcard. Avoid using too many different fonts, as this can make your postcard look cluttered.
  • Craft a Clear Headline: Your headline should be concise and attention grabbing. It should immediately convey the main message of your postcard.
  • Prominent Call to Action: Make sure your call to action (CTA) is easy to find and understand. Use contrasting colors or bold fonts to make it stand out.
  • Consistent Color Scheme: Use a color scheme that aligns with your brand and appeals to your target audience. Consistency in colors helps in brand recognition.

By following these guidelines, you can create a visually appealing postcard that effectively communicates your message and encourages recipients to take action.

14: Choosing the Wrong Postcard Mailing Services

Selecting the wrong postcard mailing services can be a costly mistake. It can result in delayed deliveries, lost postcards, and poor customer service, all of which can negatively impact your postcard marketing campaign.

Here are some tips to help you choose the right postcard mailing services:

  • Research and Compare: Look into different postcard mailing services and compare their prices, services, and customer reviews. This will help you find a service that fits your budget and meets your needs.
  • Tracking and Delivery Confirmation: Opt for a service that offers tracking and delivery confirmation. This helps ensure that you can monitor the delivery status of your postcards and confirm that they reach their intended recipients.
  • Variety of Mailing Options: Choose a service that provides various mailing options, such as first class mail and bulk mail. This flexibility allows you to select the best option based on your campaign’s requirements.
  • Reputation and Customer Service: Select a service with a good reputation and excellent customer service. Reliable customer support can help resolve any issues that may arise during the mailing process.

By carefully selecting a postcard mailing service, you help ensure that your postcards are delivered on time and in good condition, helping you achieve your marketing goals.

15: Not Measuring the Effectiveness of Your Direct Mail Campaign

Failing to measure the effectiveness of your direct mail campaign is a critical mistake. Without proper measurement, you won’t know what works and what doesn’t, making it difficult to improve future campaigns.

Here are some strategies to measure the effectiveness of your direct mail campaign:

  • Unique Phone Numbers or URLs: Use unique phone numbers or website URLs on your postcards to track responses. This allows you to see how many people are engaging with your campaign.
  • Promo Codes or Coupons: Include promo codes or coupons on your postcards to track sales and redemptions. This helps you measure the direct impact of your campaign on sales.
  • Surveys or Feedback Forms: Use surveys or feedback forms to gather information from your recipients. This can provide valuable insights into their preferences and behaviors.
  • Analytics Software: Utilize analytics software to track website traffic and online engagement. This helps you understand how your direct mail campaign is driving online activity.
  • CRM Systems: Use a Customer Relationship Management (CRM) system to track leads and conversions. This allows you to see how your campaign is contributing to your overall sales pipeline.

By implementing these measurement strategies, you can gain valuable insights into the performance of your direct mail campaign and make data-driven decisions to enhance future campaigns.


It’s not unusual for a small or fledgling business to use postcards as a major marketing device. It’s also not unusual that a well-thought-out postcard marketing campaign can lead to a significant increase in sales and revenues. By avoiding these common postcard marketing mistakes, you, too, will be better able to enjoy the rewards of this powerful marketing tool.
