Stop asking for a 15 minute call in your cold email. Here is what to ask for instead and why it gets more replies

Every single cold email I get asks for a 15 minute call. That CTA is exhausted. It signals time commitment before you've earned trust. I tested 6 different CTAs over 90 days on the same ICP with the same copy. Here are the reply rates.
"Is this even something you'd want to explore?" 4.8% reply rate. Best performer by a wide margin. Zero commitment. Just a yes or no. People reply yes, and then you book the call from there. The bar to reply is almost nothing.
"Would it make sense to connect?" 3.9% reply rate. Similar idea. Soft framing. Not "book a call," just connection. Works especially well for enterprise prospects who have gatekeeping instincts.
"Worth a quick email thread before deciding?" 3.2% reply rate. Good for cold-to-warm sequences where you've already sent one email and want a lower-friction next step.
"Open to a 15-minute call next week?" 1.7% reply rate. The standard. Not terrible but clearly not optimal. The word "call" and the time commitment in the same sentence does the damage.
"Can I send you a 2-minute video on how we did this?" 1.4% reply rate. Tried this because Lemlist was pushing it. Did not work for my audience. Higher consideration buyers do not want to watch a video from a stranger.
"Does this resonate at all?" 1.1% reply rate. Too vague. Confuses people. Skip it.
The winner is clear. Ask a yes-or-no question that requires almost no commitment. Get the reply first. Then you can have the conversation about booking a call. You're trying to start a conversation, not schedule a demo. The CTA should match that goal.
I run this through 20 pre-warmed PuzzleInbox inboxes on Instantly. At 15 emails per inbox per day, the volume gives me statistically meaningful data within 3 weeks per test.
