Signal-Based Outbound: What It Is and Why Cold Spray Doesn't Work Anymore

Cold Spray Is Dead. Signal-Based Outbound Isn't.¶

In 2024, the average cold email reply rate dropped below 1%. Mass-blast outbound — sending the same template to 10,000 contacts — stopped working. Inboxes got smarter, spam filters got tighter, and buyers started ignoring anything that felt automated.

Signal-based outbound flips the model. Instead of starting with a list and hoping someone bites, you start with intent signals — a company just raised funding, just posted a VP Sales job, just expanded into a new market — and reach out at the exact moment the problem you solve becomes urgent.

What Counts as a Signal?¶

Funding announcements, leadership changes, new job postings in relevant departments, technographic shifts (new tool adoption), geographic expansion, and G2/Capterra reviews of competitor products. Each signal tells you something about timing — and timing is the single biggest predictor of whether outbound converts.

How It Changes Reply Rates¶

Our campaigns that use signal-based targeting consistently see 8-15% reply rates versus 1-3% on traditional cold outbound. The difference isn't better copy (though that helps) — it's better timing and relevance. When a prospect just hired three AEs and you reach out about filling their pipeline, the email doesn't feel cold. It feels obvious.
