How to write a cold email that gets replies
Most cold email fails on structure before it fails on writing skill. The pattern below is what we use across every campaign we run, adjusted by industry but never abandoned.
How do you write a cold email that gets a reply?
Keep it under 80 words, personalize the opening line to the person rather than the company, lead with one clear value proposition, and close with a soft, specific call to action. Plain text outperforms designed HTML templates because it reads like a person wrote it, not a marketing tool.
The subject line
One to four words, lowercase, no punctuation. Subject lines that look like a note from a colleague get opened far more often than anything that reads like a marketing email. "quick question" or "your Q3 pipeline" will outperform "Boost Your Sales Pipeline Today!" almost every time.
The opening line
Personalize to the person, not the company. A generic line like "I came across your company" reads as templated and gets ignored at close to the same rate as no personalization at all. Reference something specific: a recent hire, a piece of content they published, or a signal tied to what you are offering.
The body
Under 80 words, one value proposition, no bullet list of features. The recipient is a stranger deciding in seconds whether this is worth their time. A short email that states one clear outcome reads as respectful of that time; a long one reads as a sales pitch.
Skip the attachments and links. Every link raises the email's spam score, and a stranger is not going to click a link from someone they do not know. Save the details for the reply or the call.
The call to action
Soft and specific beats hard and vague. "Worth a look?" or "Open to a 15-minute call next week?" outperforms "Book a 30-minute consultation" because it respects the recipient's time and reads as a peer-to-peer question rather than a scheduling demand.
Sequencing: one email is not a campaign
A three-email sequence over about seven days produces the best balance of replies without becoming a nuisance. Email one is the value-led cold open. Email two, a few days later, offers a different angle or proof point. Email three is a short breakup note, "figured this might not be a priority right now," which often gets the highest reply rate of the three. See the full sequence structure in our cold email playbook.
Mistakes that kill an otherwise good email
- Writing to a title, not a person. "Dear Marketing Director" reads as a mail merge that failed.
- Leading with your company. The first line should be about them, not an introduction to who you are.
- Asking for too much too soon. A 30-minute demo request from a cold email is a bigger ask than most strangers will accept.
- HTML formatting. Bold colors, logos, and buttons signal marketing email and get filtered accordingly.
Key takeaways
- Short subject line, lowercase, no punctuation
- Personalize the opening line to the person, not the company
- Keep the body under 80 words with one value proposition
- A soft, specific CTA outperforms a hard scheduling ask
Frequently asked questions
How do you write a cold email that gets a reply?
Keep it under 80 words, personalize the opening line to the person rather than the company, lead with one clear value proposition, and close with a soft, specific call to action. Plain text outperforms designed HTML templates because it reads like a person wrote it, not a marketing tool.
How long should a cold email be?
Under 80 words. Long emails ask for more attention than a stranger is willing to give. If the value proposition needs three paragraphs to explain, it needs to be simplified before it needs more words.
Should cold email subject lines be short or descriptive?
Short. One to four words, lowercase, no punctuation. Subject lines that look like an internal note between colleagues get opened far more often than anything that reads like a marketing subject line.
What is a good cold email reply rate?
Across our own campaigns in 13 B2B sectors, the average reply rate is 3.3%, ranging from 2.2% to 4.7% depending on how senior and how defended the buyer is. Anything above 3.5% for mid-market targeting is strong.
Does personalization actually improve reply rates?
Yes, when it references something specific about the person's own work rather than a generic detail about their company. A generic opener reads as templated and is ignored at roughly the same rate as no personalization at all.
Can an Indian company writing cold email to US buyers use the same structure?
Yes, the structure does not change by geography. What matters is that send times, follow-up cadence, and reporting are set to the buyer's time zone, not the sender's, so an Indian SaaS company selling into the US should schedule sends for US business hours.
