What to write in the first line of a cold email

The first line of a cold email is also its preview text. Here is what to cut, what to write instead, and how to write one from research in 3 steps.

People read part of a cold email before they open it. Mailbox providers show the first line next to the subject, so the opening line doubles as the preview text: a reason to open, or a reason to scroll past.

Once the email is open, the first line has one job left: get the second line read. Most cold emails spend it on a greeting, a name or a compliment that could have gone to anyone. Here is what to write instead.

Why the first line of a cold email matters

Maya, VP of Sales at Ostervane, scrolls her inbox between meetings. Under your subject line, she sees one of these:

I hope this email finds you well. My name is Alex and I...

Ostervane has four sales development roles open, all posted in the last three weeks.

The first could be from anyone to anyone. The second could only be to Ostervane, and it makes her want to know why you noticed. Same sender, same subject, same offer. Only the first line changed.

Opening lines that get cold emails ignored

"I hope you're well." Polite in a letter, filler in a cold email. It spends the preview text saying nothing.
"My name is Alex, and I'm the founder of..." Your name is already in the From field. Starting with yourself tells the reader the email is about you.
"I came across your profile." It claims research without showing any.
Fake compliments. "Love what you're building at Draymount!" reads as flattery from someone who hasn't looked. If you can't say what you love, cut it.

One test catches all of them: could this line go to 1,000 people unchanged? If it could, it's a template, not a first line.

What a strong cold email opening line does

A strong first line does three things:

Says something true and specific about them. A fact about their company, their team or their work that fits this reader and nobody else.
Gives a reason now. Something changed: a hire, a launch, a new market, a new plan. Change is what makes this week different from last month.
Points at the problem you solve. The fact leads straight into your second line, so the email reads as one thought instead of a compliment followed by a pitch.

Weak

Your name is already in the From field.
Strong
“Tara, Fennmarrow opened its Munich office in September and is hiring German-speaking account executives.”

Weak
“I came across your profile and had to reach out.”

Weak

A compliment with nothing behind it reads as flattery.
Strong
“Nina, your post on Draymount's free trial said a third of signups never hear from sales.”
Quotes their own work, and the gap you close.

Each strong line is written for one person. Sent to anyone else, it makes no sense.

Each strong line starts with them, not you, and sets up the second line.

How to write a first line from research in 3 steps

Say you sell a tool that gets new sales reps booking meetings in their first month, and you're writing to Maya at Ostervane, a 600-person logistics software company.

Step 1: Find one fact. Check their careers page, news, product updates and the person's recent posts, and note what changed in the last 90 days. The best facts are the same timing signals you'd put in your ideal customer profile. For Ostervane: four open sales development roles, all posted in the last three weeks.

Step 2: Ask why it matters now. Four new reps at once means four people ramping at the same time, and a pipeline target that counts on them being productive soon.

Step 3: Connect it to your problem. Write the fact as the first line and the consequence as the second:

Maya, Ostervane has four sales development roles open, all posted in the last three weeks. Ramping four reps at once puts a quarter's pipeline on their first 60 days.

Your third line says what you do about it. If a fact doesn't connect to anything you solve, it's trivia. Go back to step 1 and pick another.

Rules for every first line

One sentence, under 20 words. It fits the preview.
Start with them. Their name, their company or their team, never "I" or "we".
Check it's true. A wrong fact in the first line ends the email.
Keep it professional. Company news and published work, not someone's weekend.
Save the other facts. Each follow-up needs something new to say.

How Leadgenerator.io writes the first line

Agents research each company and each person, then write a personal email for every person from that research and from your knowledge: what you sell, who to reach and how emails should sound. They write each person's follow-ups the same way.

To read the first lines before they go out, use Copilot: agents do the work, and you approve, edit or reject every draft in the review queue, one at a time or in bulk. Autopilot or Copilot covers when to let them send on their own.
