01
A merge field is not a reason to care
Using a prospect's first name, company name, or industry can make a message look customized in the sender's workflow. It does not prove relevance to the buyer. If the same email still works after swapping in another company, the personalization is cosmetic.
- A token identifies the recipient.
- A signal identifies why this account matters now.
- An implication explains why the signal should matter to the buyer.
02
Signals only work when they lead somewhere
A funding announcement, hiring plan, new location, product launch, podcast quote, or leadership change can be useful. But the signal is only the starting point. The message becomes personalized when it connects that signal to a likely priority, risk, bottleneck, or decision the buyer recognizes.
- Weak: saw your company is growing.
- Better: saw the sales team is expanding, which usually exposes whether the founder's original messaging is documented enough for new reps.
- Best: connect that inference to a specific, credible offer or question.
03
The test is whether the reasoning survives review
Good personalization should survive a human review. The reviewer should be able to see the source signal, the commercial inference, the proof or context being used, and why the ask belongs in that touch. If the logic is invisible, the email may sound polished but still feel generic.
