You get about ten seconds. In that window the prospect decides whether this is a conversation or an interruption to be terminated, and almost nothing you say later can reverse that decision.
Three things make an opener survive it: you name yourself, you name the fact that this is a cold call, and you ask for something small and specific.
The permission openers
These work because they convert the prospect from someone being talked at into someone who made a decision. People who agree to give you thirty seconds listen to the thirty seconds.
- "Hi Sarah, it's Alex from Northwind. I know I'm an interruption. Can I have 30 seconds to tell you why I called, and then you can tell me to go away?"
- "Sarah, Alex from Northwind. This is a cold call. Do you want to hang up, or do you want the 30-second version?"
- "Hi Sarah, Alex here from Northwind. Is now a terrible time?"
- "Sarah, it's Alex from Northwind. I'll be honest, you don't know me. Thirty seconds and you can decide if it's worth more?"
Number three deserves a note. "Is now a terrible time" beats "is now a bad time" and beats "did I catch you at a bad time" by a clear margin, because the exaggeration makes a flat yes feel disproportionate. A prospect who is mildly busy says "no, go on" to terrible and says "yes actually" to bad.
The rule that makes these work: honour the thirty seconds. At thirty seconds, stop and check in. Reps who blow through their own stated limit teach the prospect in the first minute that nothing they say is reliable.
The specific-research openers
These only work when the fact is genuinely specific and checkable. Used with a generic fact they are worse than the permission openers, because they promise relevance and do not deliver it.
- "Sarah? Alex from Northwind. I called because you're hiring three AEs this quarter and I have a specific reason to think your ramp is going to hurt. Can I take a minute?"
- "Hi Sarah, Alex from Northwind. You opened a second location in March. I called about one specific thing that usually breaks at that point. Worth 30 seconds?"
- "Sarah, it's Alex from Northwind. I saw your post about [thing] last week and it's the reason I'm calling rather than emailing."
- "Hi Sarah, Alex from Northwind. [Competitor] switched to us in June for one reason, and I wanted to check whether that reason applies to you."
Cap your research at sixty seconds per prospect. One specific fact is enough. Two is showing off, and a rep who researches for ten minutes per call makes twelve dials a day and learns nothing from a sample that small.
The pattern-interrupt openers
Higher variance. They work well with senior titles and heavily-called markets, and land badly with people who dislike being handled.
- "Sarah, this is a cold call. Would you like to hang up now or in thirty seconds?"
- "Hi Sarah, Alex from Northwind. I'm going to be honest, I have no idea if this is relevant to you. One question and we'll both know."
- "Sarah? Alex. I've been putting off making this call all morning because I hate cold calling as much as you hate receiving them. Can I get it over with?"
- "Hi Sarah. I'm calling out of the blue and I know that's annoying. Thirty seconds?"
Number eleven earns a laugh more often than anything else on this page, and the laugh is the permission. It also cannot be faked, so only use it if it is true.
The referral and warm openers
The strongest openers available, and most teams underuse them because asking for the referral is uncomfortable.
- "Hi Tom, it's Alex from Northwind. [Name] at [Company] suggested I call you."
- "Tom, Alex from Northwind. [Name] mentioned you're dealing with the same thing they were. Is that fair, or has [Name] oversold it?"
- "Hi Tom, we met briefly at [event] in March. Alex from Northwind. Do you have thirty seconds?"
Put the name in the first sentence. It is the entire asset and burying it wastes it. And ask permission before using someone's name, because using it without asking destroys two relationships at once.
The direct openers, for very senior titles
- "Sarah? Alex from Northwind. You've got four people doing manual invoice checks. I sell software that does 80% of that. Is that a problem anyone there is complaining about?"
- "Sarah, Alex from Northwind. One question and I'll go: who owns [process] at your company these days?"
Number seventeen is a research call disguised as a sales call, and it is the most underrated opener here. It is genuinely one question, it is easy to answer, and it either gets you the right name or tells you the account is not worth working.
The six that kill calls
"How are you today?" Signals a script in four words. Costs five seconds. Returns nothing.
"Did I catch you at a bad time?" Invites the easiest yes in the conversation.
"Do you have a few minutes?" Everybody knows a few minutes means fifteen. Ask for thirty seconds and mean it.
"I'm calling to see if you'd be interested in..." The prospect has no basis to be interested in anything yet, because you have not established that they have a problem.
"We help companies like yours to..." The prospect hears a broadcast. Every vendor says this.
"Am I speaking with the person responsible for..." Reads as a screening question from a robot. Ask for the person by name, or ask who owns the process.
Testing your own
Change one variable at a time, run each version for at least a hundred dials, and measure the right thing.
The metric is the share of connects that survive past twenty seconds, not the meeting rate. Meetings are affected by everything downstream of the opener, so they are too noisy to tell you whether an opening line works. Survival past twenty seconds is a clean measure of exactly the thing the opener does.
Record the calls. The gap between what reps believe they said and what they actually said is enormous, and it is only visible on a recording.
Frequently asked questions
- What is the best cold call opening line?
- "Hi [name], it's [your name] from [company]. I know I'm an interruption. Can I have 30 seconds to tell you why I called, and then you can tell me to go away?" It works for three structural reasons: naming yourself immediately removes the scam-call signal, naming the cold call defuses what the prospect is already bracing for, and offering an explicit exit removes the pressure that causes reflex hang-ups.
- Should you ask 'did I catch you at a bad time'?
- It is one of the most-debated openers and the evidence runs against it. It invites a yes, which is the easiest word in the conversation, and Gong's analysis found it associated with materially lower success rates than alternatives. "Is now a terrible time" performs better because the exaggeration makes a flat yes feel disproportionate, and "can I have 30 seconds" performs better still because it asks for something specific and small.
- Should you say 'how are you today' on a cold call?
- No. It signals a script within four words, costs about five seconds, and produces a one-word answer that gives you nothing to work with. Prospects have heard it from every telemarketer who has ever called them, and it primes the hang-up reflex the rest of your opener is trying to avoid.
- How long should a cold call opener be?
- Under ten seconds before the prospect speaks. That is roughly twenty-five words. The opener's only job is to buy permission for the next thirty seconds, and every extra word spends goodwill you have not earned yet. If your opener includes a value proposition, it is too long.
