How to write a first line that doesn’t sound like a template
Your first line decides whether the rest gets read. Five rules for openers that sound like a person wrote them, with before-and-after examples.
Your prospect sees three things before they decide to open, archive or report you: your name, your subject line and the first line of your email in the preview. That first line is doing more work than anything else you write.
Most first lines fail the same way. They’re about the sender, they’re vague, and they could have been sent to anyone. Here’s how to write one that couldn’t.
1. Lead with them, not you
“I’m Sam from Acme and we help companies like yours…” is the fastest way to lose someone. Nobody opens a cold email to learn about you.
Before: I’m reaching out because Acme helps sales teams book more meetings.
After: Saw Northwind just opened an office in Lisbon. Congrats on the launch.
2. One specific fact beats three compliments
“Love what you’re doing at Northwind” says nothing. A specific, checkable fact shows you did the work: a new office, a hire, a funding round, a product launch, a job post, a talk they gave.
Pick one. Stacking three facts reads like a scraper wrote it.
3. Connect the fact to why you’re writing
A fact on its own is trivia. The first line earns its place when the second line explains why it matters.
Saw Northwind just opened in Lisbon. A new market usually means a lot of new partners to find, which is exactly what we help with.
If you can’t connect the fact to your reason for writing, it’s the wrong fact.
4. Keep it short
A first line that fits in the inbox preview gets read whole. Aim for one sentence, and cut every word that isn’t doing a job: “just”, “quickly”, “I hope this finds you well”.
5. Don’t fake it
“Loved your recent post!” when you didn’t read it is easy to spot and hard to recover from. If you’re writing at scale, only reference facts you actually have in your list.
Doing this for a thousand people
You can’t research every prospect by hand, and you don’t need to. Put the facts in your lead list as columns: title, city, the funding round you spotted, the job they posted. Then:
- Merge fields drop each fact into the right place, so the email reads naturally.
- An AI first line can turn those facts into a sentence that sounds like you wrote it. In Norbelys it only uses the columns you pick, so it never invents a compliment.
- Review a sample before you launch. Read ten emails out loud. If any of them would make you cringe as the recipient, fix the template, not the email.
A good first line won’t save a bad offer. But a bad one will make sure nobody ever reads the offer at all.
