Cold email opening lines, grouped by the reason you are writing, with a note on when each one backfires.

What a cold email opening line has to do

A cold email opening line is the first sentence after the greeting. In most inboxes it also appears in the preview next to the subject line, so the reader sees it before they decide to open the email at all.

That makes it the one sentence that has to prove the email was written for this person. Everything below is a library of cold email opening lines that do that, grouped by the reason you are writing. Every line on this page was written for this page; replace every placeholder with something true.

Why each type works, and where the facts behind it come from, is explained in how to write a cold email. This page is the part you copy from.

Why the opening line matters more than the rest of the sales email

Prospects decide in the preview whether a sales email deserves their time. They see who sent it, the subject line and the start of the first sentence, and that is often all they read.

A generic opening line tells the prospect the email went to a list, so the rest is skipped however good it is.

A specific one does the opposite: it gives the prospect a reason to read the second sentence, which is where the offer starts. That is why most of the effort in a cold email belongs in the first line, not the last.

It is also the part that is hardest to fake. Common openers can be generated in bulk; a detail about this prospect, this week, cannot, and prospects have learned to tell the difference.

Four rules every good opening line follows

• It is about the prospect. The first words are about them or their company, not about you or your product.
• It is specific. It names something you could only know by looking: a post, a hire, a launch, a mutual contact.
• It is recent. Last week's change reads as attention; last year's reads as a database.
• It is short. One sentence, readable in the preview, that makes the second sentence worth reading.

If a line would work in an email to a thousand other people, it is not an opening line. It is a greeting with extra words.

Pick an opener by what you know about the prospect

If you know nothing specific about the prospect yet, spend two minutes finding something before you reach for a problem-first line. A real detail almost always beats a well-phrased generic one.

Opening lines based on something they published

These work when the prospect writes posts, gives talks, or appears on podcasts. The line shows you read it and have a view, not just that you saw it.

• "Your post on {{topic}} made a point most people in {{industry}} avoid: {{theirPoint}}."
• "In your talk at {{event}} you said {{claim}}. We see the same thing with {{similarCompanies}}."
• "You wrote that {{problem}} is harder than it looks. The part that surprised me was {{detail}}."
• "Heard you on {{podcast}} talking about {{subject}}, especially the part about {{specificPart}}."
• "Your comment on {{person}}'s post about {{topic}} is the reason I am writing."

Opening lines based on a change at their company

A change at the company is often the real reason a cold email is timely. The opening line names the change; the second sentence connects it to what you do.

• "Congratulations on {{fundingRound}}. Teams that raise usually {{whatHappensNext}} within a few months."
• "Saw that {{company}} is launching {{product}} in {{market}}."
• "Noticed {{company}} just opened an office in {{city}}."
• "With {{acquiredCompany}} now part of {{company}}, I imagine {{integrationTask}} is on someone's list."
• "Your new {{feature}} page mentions {{goal}}, which is usually where {{problem}} shows up."

Opening lines based on who they are hiring

Open roles say what a company is building next, often more clearly than its website. They also tell you which team feels the pain you solve.

• "Saw you are hiring {{roleCount}} {{role}}s, which usually means {{implication}}."
• "Your job post for a {{role}} mentions {{requirement}}, so I guess {{problem}} is on the table."
• "Looks like {{team}} is growing fast at {{company}}."
• "You are building a {{team}} team from scratch, going by the roles you posted this month."

Opening lines based on shared context

A real point in common, an event, a community, a customer, turns a cold email into a warm one. It has to be real, and it has to be recent enough to be remembered.

• "We were both at {{event}} last week; I was in the session on {{session}}."
• "We are both in {{community}}, and your question there about {{topic}} stuck with me."
• "We work with {{sharedCustomer}} too, on {{differentPart}}."
• "You and I both came from {{previousCompany}}, a few years apart."

Opening lines based on a referral

A referral is the strongest opener there is, and the easiest to damage. Use a name only with that person's permission, and say exactly what they told you.

• "{{referrer}} suggested I get in touch; they mentioned you are working on {{project}}."
• "{{referrer}} at {{company}} said you are the person who owns {{area}}."
• "When I asked {{referrer}} who thinks hardest about {{topic}} at {{company}}, they named you."

Opening lines that lead with the problem

When you have no personal detail, open with a specific problem that people in the prospect's role recognize. It works only if the problem is sharp enough to name in a sentence.

• "Most {{role}}s I talk to at {{companyType}} companies say {{problem}} gets worse after {{milestone}}."
• "When {{companyType}} teams move to {{change}}, {{problem}} usually shows up in {{place}}."
• "Quick question about how {{company}} handles {{process}} today."

Opening lines for follow-up emails

A follow-up needs an opening line too. It should add something new instead of pointing at the last email.

• "One thing I left out last time: {{newPoint}}."
• "Since I wrote, {{company}} {{newChange}}, which makes the question more timely."
• "Different angle on my last note: {{angle}}."
• "Here is the example I promised: {{example}}."

When and how often to follow up, and the full emails, are in the follow-up email after no response guide.

Cold email opening lines to stop using

"I hope this email finds you well" belongs in a message to someone who already knows you. How to open warmer emails is covered in the guide to email greetings.

How long an opening line should be

One sentence, short enough that the useful part fits in the inbox preview. How much of the first line shows depends on the email client and the screen, so put the specific detail near the start of the sentence, not at the end.

A long opener usually hides a second job: introducing you, explaining the company, or setting up the pitch. Move those to the second sentence or cut them. The opening line only has to earn the next sentence.

How formal the opening line should be

Match the register of the person you are writing to. A founder who posts casually will read a stiff opener as a template. A general counsel at a bank will read a jokey one as unserious.

The prospect's own writing is the best guide: their posts, their comments, the way their company's site talks. When in doubt, plain and direct is safe in almost every market; clever is not.

Where the details for an opening line come from

Researching a company quickly and reliably is covered in company research for sales, and doing it for LinkedIn in particular in LinkedIn prospecting.

Personalizing opening lines when you send many emails

Writing a new first line for every prospect is slow. Teams that send in volume usually personalize the opening line by segment and save full personalization for the accounts that matter most.

• By trigger: everyone who raised funding this month gets the same opener with their company name and round.
• By role: a problem-first line written for one role, sent only to that role.
• By hand for the top accounts: a line written for each person at the accounts that justify it.

AI tools can draft first lines from a profile or a post. Read every one before it goes out; a wrong detail is worse than none. The trade-offs are covered in AI for email marketing, and the wider method in personalized outreach.

How to write your own cold email opening line

1. Find one true, recent detail

   Look at their activity, their company's news and their open roles, and pick the one thing most connected to what you offer.

2. Choose the opening type

   Match the detail to a type on this page: their content, a company change, a hiring signal, shared context, a referral, or a problem.

3. Write it in one sentence

   Put the detail near the start, leave out your name and company, and cut anything that sets up the pitch.

4. Check the second sentence

   The opening line should make the second sentence feel necessary. If they do not connect, change one of them.

5. Read it as the prospect

   Ask whether it could have been sent to anyone else. If yes, start again with a more specific detail.

What a good opening line does not change

A personal first line makes a cold email feel less like marketing. In the United States it is still commercial email under the CAN-SPAM Act, and the FTC states that the law makes no exception for business-to-business email.

• The subject line must not be deceptive, so it cannot promise what the opening line does not deliver.
• Your location has to be in the email, as a valid physical postal address.
• An opt-out has to be offered, and requests honored within 10 business days.

The FTC puts the penalty at up to $53,088 for each email that breaks the law. The rest of the cold email rules are in the cold email guide.

Common opening line mistakes

• Fake personalization. A merge field that says "I loved your recent post" with no detail.
• A wrong detail. Congratulating someone on a role they left, or a round the company did not raise.
• Starting with yourself. Your name, your company, your product in the first words.
• Flattery. Compliments that do not connect to anything you do.
• A question they cannot answer yet. "What are your plans for next year?" before they know who you are.
• Reusing an opener too widely. The same "specific" line sent to five hundred people stops being specific.

An opening line inside a full cold email

The template below shows where the opening line sits and how the second sentence picks it up. It was written for this page; more complete emails are in the cold email templates library.

Subject: {{role}} hires at {{company}}

Hi {{firstName}},

Saw you are hiring {{roleCount}} {{role}}s, which usually means {{implication}}.

When {{companyType}} teams grow {{team}} that fast, {{problem}} tends to land on {{ownerRole}}. We help with {{outcome}}, most recently for {{similarCompany}}.
