The Do's of Postcard Marketing

Even if you do know how to send business postcards, you should know how to do it right. Find below some important and necessary do's of a postcard marketing campaign.

Test Your Postcards

No matter what you have designed and which target audience you have selected for mailing, it all comes down to your campaign performance. You cannot know what aspect of your campaign is the reason for your campaign's success (or failure). Hence, it makes sense to test your postcards before conducting a large campaign. Start small and measure everything. Use small tweaks to know the best design, offer, audience, and copy combinations.

Track Engagements

To track responses and engagements after you send advertising mail postcards, you need to include some trackable features. QR codes, trackable phone numbers, unique email addresses, redeemable discount codes, and pURLs are all useful to track engagements. You can take your pick or use more than one option to track your campaign results easily.

Personalization

Always personalize your postcards. It doesn't matter if you are only able to personalize your postcards using the recipient's first name—just personalize as much as possible and wait for the results.

PostGrid Print & Mail API offers variable data printing technology (VDP). It allows you to change the text, font, background image, and other elements of the postcards. Customers are more likely to pay attention when the collateral has their name, location, or custom offers tailored to their needs. These personalized postcards feel like one-on-one communication, boosting open rates and conversions. You can also leverage this technology to align the design with your business messaging, making your brand easily recognizable.

Geotargeting

Segment your mailing list based on specific geographical factors, such as ZIP codes, cities, towns, and subdivisions. Combine this with demographic data, such as income and age, to refine your targeting.

For instance, you are opening a new gym in New York and want to drive foot traffic by offering a free one-week trial. Instead of mailing postcards to everyone in New York, you can implement geotargeting to select postal codes within a four-km radius of the new location. You can narrow the list to people aged 25–45 who are likely to be interested in fitness. This hyper-local strategy will increase the likelihood of visits and conversions while keeping mailing costs low.

The Don'ts of Postcard Marketing

Fail to Proofread

Don't conduct a campaign before being 100% sure of everything. Your design should be on-point, and your mailing lists should be well-prepared. Make sure your postcards can convey your message properly and are simply convincing. Ask your coworkers, employees, and third parties for feedback to understand things better and make the necessary changes.

Forget to Follow Up

Once your postcards are delivered to the intended recipients, it is the commencement of the next stage of your marketing plan to follow up. Instruct your sales team to follow up with the recipients, especially in the case of account-based marketing.

How to Measure the Success of Your Postcard Campaigns?

Set Your Goals

Decide whether you want to generate leads, boost traffic, or increase brand awareness. The specific goal will help you design your campaign, understand whether it made the intended impact, and determine how to improve it. This clarity aligns your camping with measurable business outcomes.

Incorporate Trackable Elements to Monitor Responses

Add promo codes, QR codes, URLs, or dedicated phone numbers to attribute results accurately. When someone scans the QR code or enters the PURL or promo code, it will immediately register as a digital interaction. The timestamped data, along with the customer’s location, will provide instant visibility into which regions are engaging more and when. You can use these insights to optimize your messaging, design, and targeting in future campaigns.

Calculate Campaign Costs

Break down every cost involved, including printing, postage, design, copywriting, data purchase, and software or platforms. This will give you a clear picture of how much you are spending to acquire each lead. Using this, you can optimize your budget allocation and identify future cost-saving opportunities.

Measure the Revenue Generated

Track the amount of money that came directly from your postcard campaign. This can be made through online purchases using promo codes or long-term customer value if the postcard leads to a subscription. By assessing the dollar value for each conversion, you can justify your campaign spend and understand the financial impact of your efforts.

Calculate Return-on-Investment (ROI)

Use the formula mentioned below:

ROI (%) = [(Revenue – Cost) / Cost] × 100

A positive ROI means that you have made more than you have spent. However, a negative ROI means you need to reassess your strategy. By calculating the ROI, you can determine whether or not your campaign is generating more revenue than the amount spent on it.

Track Response Rate and Cost Per Acquisition (CPA)

These metrics will give a deeper insight into campaign performance. For instance, if your response rate is high but the conversion rate is low, consider improving your direct mail strategy. With CPA, you can understand how efficiently you are acquiring new customers. You can use these insights to fine-tune your messaging, targeting, and design for better performance in future mailings.
