"Send Me Some Info" Is a Polite Hang-Up. Treat It Like One.
The email you send after "send me some info" almost never gets opened. An analysis of over 4 million cold emails explains why length is only half the problem, and what actually earns a reply.
"Send me some info" almost never means someone is interested. It's the politest exit a prospect has, and most reps hand it to them without a fight: "sure, what's your email?" Then they wonder why the follow-up disappears into a folder nobody opens.
Here's the part that made me actually change how I write that follow-up. An analysis of more than 4 million cold emails, pooling data across Boomerang, Lemlist, Instantly, and Gong, found emails between 50 and 125 words get an 8.2% reply rate, roughly 2.4x higher than emails over 200 words, which drop to 3.9%. Length alone explains a meaningful chunk of why a follow-up email dies. But it doesn't explain all of it, and the part it misses is the actual point of this post: a short email with nothing specific in it is still just a shorter version of the same folder-filler.
So the goal on the call itself isn't to get to the email faster. It's to find out whether there's a real reason to keep talking, and to book something concrete before you hang up, because the email, however well-written, is not going to do that work for you.
1. Don't say yes right away
The reflex is "Sure, what's your email?" That teaches the prospect the brush-off worked, and hands away the one thing you could have traded for a real answer. Slow it down instead: "Happy to. So I send the right thing and not a 12-page PDF you'll never open, can I ask you two quick questions?" Almost nobody refuses two quick questions.
2. Find out what "info" is standing in for
"Info" is a placeholder for a question the prospect hasn't said out loud. Ask: "When you say info, what do you want to see in there, pricing, how it works, or whether it fits a team like yours?" The answer hands you the real objection. Pricing means they're comparing quotes. "How it works" means curiosity without conviction. "Whether it fits" means there's a live deal worth pushing for a real meeting.
3. Trade the info for a reason to meet
Offer both together, not one instead of the other: "I can send that over. Most people skim it and still have the same three questions after. Give me 15 minutes Thursday, I'll walk you through the one part that matters for your team, and send the deck right after so you have it on file." The email becomes the reward for the call, not a replacement for it.
4. If they still only want the email, pin down the follow-up
Don't let them off with a vague "sounds good." Tie the next contact to an actual date before you agree to send anything: "I'll get it to you today. Once you've had a look, what's a better day for me to check back, Tuesday or Wednesday?" A prospect who won't give you a callback day was never buying from a PDF regardless of what you sent.
5. Write the email like the data says to, not like a brochure
Given what a 4-million-email dataset says about length, the actual formatting rule is: 50 to 125 words, one question, no attachment on the first send. Reference their exact words from the call, ask the one question that moves it forward, and stop.
"You mentioned you weren't sure this fits a team your size. The closest account to yours runs nine reps and had the same worry. Worth 15 minutes to compare notes on Thursday?"
That's under 40 words and it isn't generic; it's short and specific, which the data says beats either quality alone. A wall of text with a brochure attached gets archived regardless of length. Three sentences that reference nothing the prospect actually said gets archived just as fast, only faster.
One anti-pattern to kill either way: the "just circling back" email. It says nothing, asks nothing, and tells the prospect you have no new reason to talk. Every follow-up needs a fresh hook, a question, a relevant account, a deadline, something.
Why this actually works
The pattern I keep seeing: reps who send a polished one-pager to every "send me info" get almost no replies, because a PDF answers a question nobody asked out loud. Cut the attachment from the first email, keep it inside the length band the data supports, and tie it to one question the prospect actually said on the call. The reply rate changes, because now there's something specific to answer instead of something generic to file.
The next time you hear "send me some info," don't reach for the attachment. Reach for the two questions that tell you whether the deal is real in the first place.
