4 Hidden Signals Your Thank-Yous Are Sending:
(And How to Get Them Right)

Every time you write to donors, whether you know it or not,
you're sending signals.
Are you showing supporters they matter? Or subtly communicating something else?
Right down to your gift acknowledgements, or thank-you letters, even the smallest choice in tone and word choice can make a massive difference to the signal you send.
Sadly, thank-yous are still among the most neglected messages of all.
Today we're going to explore how you can get those signals
right.
1️⃣ Signal of Respect — or Signal of Transaction?
Does your thank-you focus only on how much someone gave? Or does it focus on who gave the gift, too?
Does your letter sound like a perfunctory receipt... or a genuine message of gratitude written by a living, breathing human?
One of the quickest ways to diminish a thank-you is to treat it like a receipt. That's because it sends a signal of transaction, that shows
the donor what matters isn't who they are, but what they gave.
Here are transaction words that make no donor feel loved, ever:
Your donation of $XX has been processed.
So instead of sending a transaction signal, why not signal warmth and respect? Like this:
Because of your kind gift of $50, a family
in crisis has food and shelter tonight. And tomorrow, with your love beside them, they can begin to rebuild.
We talked about sharpening your writing before. But with thank-yous, it's a special kind of signal you send. And that signal is
not about a transaction.

2️⃣ Signal of Relationship — or Obligation?
Does your thank-you celebrate the relationship and shared values?
Or does it subtly pressure with give-again phrases?
I'm not saying you can't prime a relationship that you hope will last... but it's the way priming happens that changes everything.
For example:
We hope you'll continue to support us.
vs.
We hope you'll be with us for years to
come.
Do you see it? In the top example, it's the supporter's money that's valued in this thank-you letter, right down to an indirect ask for more.
But in the bottom example, it's "you" we value -- you the supporter, your kindness, your togetherness with us, and we're in it for the long haul.
👉 Cool brain science tip? Obligation-based language can trigger something called reactance theory, that often triggers the exact opposite behavior as individuals see their control is being taken away. But with relationship-based language, we can boost commitment and satisfaction... two of the key drivers of loyalty.
3️⃣ Signal of Story — or Self-Promotion?
