A common worry of customers that are interested in starting a direct mail campaign is that their mailer will not get opened or read by their targeted recipients. It is true that sometimes generic, one- size fits all direct mail can get overlooked, but direct mail that is personalized gets opened. Regardless of how far we’ve come from communicating exclusively through letter mail, there is still a bit of magic to receiving a letter with your name on it.
In a recent study, 84% of consumers surveyed said they’d be more likely to open a piece of direct mail if it’s personalized. Because of the better open rates of personalized mail, letter mail recipient’s response rates go from 2% with un-personalized mail to 6.5% when it’s personalized. Some studies of mailing campaigns even experienced as high as an 8% jump in responses rate that seemed to be dependent on the depth of personalization in the mailer. This is where variable data printing comes in.
What is Variable Data Printing?
VDP lets you change text, images, or offers on each printed piece without slowing down the print run. The process involves pulling information like name, location, purchase history, etc. from a database to customize each piece of mail. In comparison to standard and static bulk mail print runs, this is where VDP stands out.
Examples of variable data that can be applied to your lettermail:
· The recipient's name in the greeting and throughout the body copy
· Personalized offers based on purchase history or customer segment
· Location-specific details, like nearby store addresses or regional promotions
· Custom images or graphics matched to demographics or interests
· Unique QR codes or URLs for tracking individual responses
Why Does Personalization Matters in Lettermail?
All marketers know that personalization improves engagement across all forms of outreach. People are more likely to respond to any form of content that feels relevant to them specifically. Letter mail in general has an advantage over advertisements in the digital space. As opposed to messaging on a screen, mail is tangible and does not compete for attention as much as digital ads do. It is easy to see how VDP amplifies the benefits of letter mail when considering the marketing advantages of any sort of direct mail.
How VDP works with Letter Mail Specifically
There are many practical applications of VDP, some examples include
· Personalized Greetings
· Custom Body Copy
· Variable Offers/Discounts
· Personalized PURLS or QR Codes
These examples differ from the things you can do with postcards, as postcards don’t have as much space as a letter does and usually are ordered with different goals in mind, but they are still possible to do with VDP.
Why use VDP when creating a post card mailing?
Usually, variable data printed post cards have some sort of visual personalization, which could include:
· Images – ex. matched to a past purchase category
· Location-based offers
· Map – ex. recipients nearest store location
The point for post-cards working with VDP is to maintain cost efficiency while still making your messaging feel personal.
The Business Case for VDP in Bulk Mail
Some marketers assume that personalization and bulk mail efficiency are at odds — that customizing thousands of pieces must mean sacrificing speed or driving up costs. In reality, modern VDP technology is built specifically for high-volume runs. The variable data is merged with the print template digitally, so you get the speed and cost-efficiency of bulk production with the impact of individualized messaging.
The result is a campaign that:
Increases response rates — personalized mail consistently outperforms generic mail in response and conversion metrics
Improves ROI — better response rates mean more value extracted from the same mailing budget
Strengthens brand perception — customers notice when a company gets the details right
Supports data-driven testing — because content varies by segment, you can A/B test messaging, offers, and design within the same mail run
Getting Started with Variable Data Printing
To make the most of VDP in your next letter mail or direct mail campaign, start with clean, well-organized customer data. The quality of your personalization is only as strong as the data behind it — names, purchase history, location, and segment information all need to be accurate and up to date.
From there, work with a print partner who has the technology and experience to execute VDP at scale, so your campaign maintains consistency and quality across every single piece, whether you're mailing five hundred letters or fifty thousand.
Direct mail isn't going anywhere — in fact, in a digital-first world, a well-crafted letter can stand out more than ever. Variable data printing is what transforms a standard bulk mail run into a personalized experience for every recipient, driving stronger engagement and better results for your campaigns.
