Pulling out a really important from my latest guide (scroll to the button below to read full thing).
Word association in your email copy
Your audience builds mental associations with you, names, brands, products, services and subject matter topics through repeated exposure.
Every email you send, the subjects you cover, the words you use, the tone you adopt - adds to that association
Over time, the brain builds a prediction: "when I see this sender, I expect this."
(predictive coding)
That prediction is enormously valuable when you maintain it
It's why trusted senders get opened more consistently
The brain leans in before the subject line is even read
But when you break it, even slightly, friction appears.
What word association dissonance looks like:
A productivity software brand that has spent six months emailing about efficiency and features sends an email saying, "you're not just a customer - you're part of our family."
The language is warm, the intention is good, but the subscriber's brain has been trained to expect practical and direct.
The shift creates a small but real disconnect - they feel slightly like this email wasn't written for them
→ Subject matter mismatch: you're known for one topic, and suddenly your email feels like it's from a different brand. The words don't connect to what subscribers associate with you
→ Tone mismatch: you've built a direct, no-nonsense voice and suddenly your email is warm and effusive. Or the reverse.
→ Seasonal language problem: you send commercial content all year and then shift to "this season is about more than the gifts we give." The language is fine. The association wasn't built to support it.
The questions to ask before every email:
→ What does my subscriber associate us with based on the last six months of emails?
→ Does the language in this email fit that association, or does it require a mental shift?
→ What would someone who's read my last ten emails expect this to sound like?
The association you build is built word by word, email by email.
It's one of the most commercially valuable things your email programme creates.
