PropFuel’s Formula: The Science Behind Better Member Engagement

Brittany Lancor

June 26, 2025

Spoiler alert: It’s not magic. It’s psychology.

You spend hours crafting the perfect member email. You carefully select the subject line, fine-tune the content, hit send to thousands of recipients…and then you wait. But all you see is a 2% response rate. Maybe 3%, if you’re lucky.

Sound familiar?

Here’s the thing: it’s not your fault. Traditional association communications are often built around what the organization wants to say, not what the member is looking for and definitely not how the human brain processes information. At PropFuel, we’re flipping that approach. Instead of working against psychology, we’re building a platform around it.

The result? Our clients routinely see engagement rates three times higher than industry averages.

So what’s our “secret”? We’ve found it comes down to two psychological principles that most associations overlook: cognitive fluency and pattern interrupt.

The Path of Least Resistance: Cognitive Fluency

Cognitive fluency is a psychological concept that refers to how easy something is for the brain to process. It’s a fancy way of saying “the easier something is to understand and act on, the more likely people are to do it.”

When content feels clear and simple, the brain says “yes.”

When it feels confusing or complicated, it says “maybe later” (AKA...probably never).

Unfortunately, most association communications create the opposite experience. Think about a typical association newsletter, often filled with: 

  • Long paragraphs of text
  • Multiple messages jammed into one email
  • Calls-to-action buried at the bottom
    Five links, four buttons, and a footer longer than the content

That’s not easy. That’s cognitive friction.

How PropFuel Makes It Easy

PropFuel helps you incorporate cognitive fluency naturally. Here’s how:

  • One question at a time. Instead of lengthy forms or multi-paragraph emails, we ask a single, focused question. For example: “What’s your biggest professional goal this quarter?” That’s it. Simple. Clear. Easy to answer.
  • Response options that match the question. Need a quick answer? Use yes/no. Looking for insight? Use open text. The format fits the question, not the other way around, keeping things easy and natural for your members.
  • Relevance built-in. Because PropFuel integrates with your AMS and other systems, each message is tailored to the member. That means no more irrelevant emails that prompt your members to disengage.

When content is easy to understand and act on, people engage. PropFuel makes that happen on purpose.

Breaking the Pattern: Pattern Interrupt

Now let’s talk about attention. Your members receive hundreds of emails a day. Their brains have learned to filter out anything that looks like another marketing message. And most association emails follow the same pattern:

  • Logo at the top
  • Generic greeting
  • Wall of text
  • Multiple calls-to-action
  • Footer longer than the body of the email

By the time they’ve scanned the first few lines, their brain has already decided: “Nothing new here.”

This is where pattern interrupt becomes powerful. A pattern interrupt is something unexpected. It breaks the brain out of autopilot and demands attention. It doesn’t have to be dramatic, just different enough to stand out.

How PropFuel Breaks Through the Noise

PropFuel’s messages don’t look or sound like typical emails. Here’s what's different:

  • We talk like real people. Instead of a formal tone, we might open with: “Quick question, Sarah…” This immediately signals that this isn’t just another blast email.
  • Clean, focused layout. Our emails are visually simple. They focus on one thing. No competing buttons or paragraphs of fluff. Just one question, leading to one action. 
  • Instant interaction. We make it easy to respond right in the message. No extra clicks. No delays.
  • Beyond just email. While most associations rely solely on email, PropFuel uses web pop-ups and SMS as well, reaching members across multiple channels, each one designed to feel different and inviting.

When a message looks different, sounds different, and feels different, the brain takes notice. And when it’s also easy to respond to? That’s when engagement happens.

Why This Combo Works

Pattern interrupt grabs attention. Cognitive fluency lowers the barrier to action. Together, they create a concept psychologists call “effortless attention.” It’s what allows people to scroll social media for hours while avoiding a 10-minute task they’ve been putting off.

PropFuel applies that same principle to association engagement. And the numbers speak for themselves.

What the Data Shows

Our 2024 benchmark data from 201 association clients shows:

  • An average response rate of 8.1%, compared to a 2.7% industry click-through rate
  • Average open rates of 41.7%, compared to the nonprofit industry average of 26.6%
  • 13.6% response rates for small, targeted campaigns vs. 4.1% for large broadcasts

These aren’t marginal improvements. They’re game-changing shifts in how associations connect with their members.

The Real Value Happens After the Response

Of course, getting that first response is only the beginning.

Because PropFuel collects actionable data from every member interaction, and because you can respond immediately, your communications become more relevant over time. Your members start to expect something useful when they hear from you. They begin to associate your messages with value. That’s when trust builds. 

That’s when engagement becomes habitual.

The Bottom Line

Your members aren’t ignoring your messages because they don’t care. They’re ignoring them because their brains are overwhelmed, and your communications feel like work.

PropFuel works because it’s built around how people actually think, make decisions, and interact with information. It’s designed for clarity and optimized for attention.

The associations winning the engagement game aren’t necessarily the ones with the biggest teams or the largest budgets. They’re the ones that understand the psychology of connection and use it to their advantage.
