While there is no one-size-fits-all answer, opting for standard postcard sizes like 4″ x 6″ or 5″ x 7″ ensures cost-effectiveness and easy mailing. However, larger, or uniquely shaped postcards can help your message stand out. There is no limit to postcard size, though choose wisely.

Consider the purpose of your postcard. If it aims to showcase vibrant visuals or provide detailed information, a larger size might be ideal. On the other hand, if you want to convey a short and compelling message, a smaller size can deliver the impact you desire. Remember to strike a balance between grabbing attention and ensuring practicality.

#2 Key Visual Image/Graphic

A captivating visual image or graphic is the cornerstone of any successful postcard mailer, it catches the recipient’s eye and sparks their interest. When selecting an image, ensure that it aligns with your brand identity and effectively communicates your message.

High-quality, professional images of your products, people or services can have a greater impact than generic stock photos. Consider investing in custom photography or illustrations that reflect the unique aspects of your business. If you are promoting a specific product or service, display it prominently in the visual.

#3 Strategic White Space

White space, or negative space, refers to the intentional blank areas in your postcard design. These areas play a vital role in maintaining a clean and uncluttered layout. White space helps guide the recipient’s attention to the different key elements of your postcard, such as the visual image and message.

While the visual elements are crucial, it is equally important to leave white space on your postcard to accommodate essential compliance elements. These areas include space for the stamp, address, post office markings, and any additional information required by postal regulations. By incorporating these compliance elements seamlessly into your design, you ensure that your postcard meets all necessary mailing requirements and reaches its intended destination without any issues.

Post offices typically apply barcodes, postage labels, and other markings to process and deliver the postcard efficiently. Failing to allocate sufficient room may result in valuable information being obscured during the mailing process, or an undeliverable piece of mail. As a general guideline, leave at least ½ inch (1.27 cm) of empty space at the bottom of the postcard to accommodate these markings without interfering with your design or message.

By strategically incorporating white space, you can create a sense of balance and enhance readability. It allows the recipient’s eyes to rest, making it easier to absorb the information you present. Moreover, white space helps ensure compliance with postal best practices and will guarantee that it gets stamped and delivered, quickly and easily. Partnering with a knowledgeable print and mail provider will help. Preferred Direct will assist with any design assistance needed so your postcard is a success.

#4 Strong Call to Action/Clear, Concise Message

The success of your postcard hinges on delivering a clear and concise message that resonates with your target audience. A strong call to action (CTA) is the driving force behind your postcard’s conversion potential. For a successful direct mail marketing campaign, you must have a clear message – to have a clear message, we must start with having a clear goal. Take time to define what your campaign goal is and do your best to state it in one complete, yet powerful thought. This approach will boost your ROI and bring in the most qualified leads.

Keep your message concise, using clear and urgent language. Ensure that it aligns with your overall marketing strategy and resonates with your target audience. Consider the pain points your product or service addresses, the competitive advantages you may have, and emphasize the unique value you bring. Incorporate a sense of urgency in your CTA to motivate recipients to take immediate action.

#5 Unique Elements: QR Codes, Coupons, Perforation

QR codes have recently gained popularity and have the ability to link printed items directly to specific landing pages or digital content, making it easy for recipients to access more information online or take advantage of special offers.

Coupons or discount codes are highly effective in enticing recipients to make a purchase, set up a meeting, or visit your physical or online store. Providing exclusive deals through postcard promotions can significantly boost response rates. Another creative element is the addition of perforation, which allows recipients to tear off a section for a specific purpose, such as redeemable vouchers.

By including QR codes, coupon codes and custom URLs exclusive to your postcard campaign, you can track ROI metrics such as page views, coupon redemptions, and engagement, allowing you to make data-driven decisions and maximize your marketing budget.
