Despite the fact that digital marketing holds the promise of personalization at scale, marketers are still struggling to bring it fully to fruition. The blockade? Their own tech stacks.

According to eMarketer, 42% of brand marketers and 47% of agency marketers in North America cite limited platform integration as their top barrier to personalization, findings from an October 2025 survey conducted by StackAdapt and Ascend2.

The urgency, eMarketer reports, is palpable. A study by Amperity found that nearly three-quarters (74%) of shoppers say they are more likely to make a purchase when they get a personalized experience, and 83% say personalization is important when choosing where to shop. But consumers are noticing a gap. Some 57% of shoppers say that even brands claiming to personalize still deliver experiences that feel generic.

It’s All in the Execution

With digital marketing struggling to deliver personalized experiences despite having mountains of data, personalized printing (when well-conceived and executed) is still offering that “something special.” Is it tangibility? Is it dimensionality? Or is it simplicity? Sometimes less is more, and the simplicity of a few well-chosen data points can often win out over poorly executed, tech-stack-limited digital alternatives.

But the key, of course, is “well executed.” One thing not in the survey (and not in most surveys), for example, is the ability of the printer (or digital marketing agency) to guide and direct their clients to make smart choices. Do they have the right list? Is the right data being selected from that list? Is the message actually relevant to the recipients?

There are factors beyond the data too. Does the headline (or subject line) grab you? Is the call to action motivating? (Is there even a call to action?) How about, “Will the mail piece reach the target audience in time?”

Sorry, Home Games Are Over!

Take, for example, the university lacrosse schedule that was mailed out to a highly targeted audience of alumni lacrosse-lovers—fans, former players, and coaches. While the piece did, in fact, arrive during the school’s lacrosse season, it landed after all of the home games had already been played.

That's not a tech-stack problem. It’s a planning problem. Which leads to the question. Whose job is it to make sure a piece lands at the right time? Did the printer notice that the job was arriving too late for recipients to make it to the home games? Was it their job to do so? If they did notice, did they say something? Or did they let it go, figuring it's the school's problem (GIGO) because they didn’t want to risk losing the job?

The truth is—whether print or digital—the tech stack is rarely the root of the problem. Neither is the data. What personalization has always required, at its core, is someone to be paying attention.
