What is relevance-based personalization vs token-based?

You've probably received both kinds of cold emails without realizing there's a name for the difference. One starts with "Hi Sarah" and then immediately talks about the sender's product. The other opens with something specific to you, your company, your moment. That gap is what separates token-based from relevance-based personalization.

Token-based personalization swaps data into fixed template slots. Things like {first_name}, {company}, or {job_title}. It's fast, easy to scale, and honestly better than no personalization at all. But recipients have seen it so many times that it barely registers anymore. It signals effort without demonstrating any real understanding of who they are.

Relevance-based personalization is different. Instead of inserting a name, it explains why the outreach makes sense for this specific person right now. It connects their actual situation to what you're offering. It requires research, not just a spreadsheet.

Side by side, you can feel the difference immediately:

• Token-based: "Hi Sarah, I see you're VP of Marketing at TechCorp."
• Relevance-based: "Noticed TechCorp just announced a Series B. When marketing teams scale quickly after a raise, keeping their email deliverability clean often falls through the cracks. That's usually when we hear from people."

The first is technically personalized. The second feels personal. There's a real difference.

In practice, you don't have to choose one or the other. Use tokens for the basics like names and companies. Save relevance-based hooks for your opening line and your value proposition, the two places where a reader decides in two seconds whether to keep going. If you're personalizing cold emails at scale, relevance is also what lets you make a cold email actually land.

And one honest caveat: relevance-based personalization is harder to scale. You can't automate genuine understanding. Some teams get around this by segmenting tightly and writing relevance-based copy for each segment rather than each individual. That's a reasonable middle ground.

If you're stuck deciding how much personalization effort to invest, a good rule of thumb is to weight it by prospect value. High-value targets get deep relevance. Broad outreach gets tokens plus a segment-level hook.
