How to Write Cold Emails That Get Replies

Cold email remains one of the most effective B2B outreach channels when done correctly. The difference between a cold email that gets ignored and one that generates a reply comes down to a handful of measurable factors. Our free cold email grader evaluates each of these factors so you can optimize before hitting send.

Research from Lavender, Gong, and other sales engagement platforms consistently shows that cold emails between 50 and 125 words achieve the highest reply rates. Emails over 200 words see a sharp decline in engagement. Your subject line should be 3 to 8 words, lowercase, and free of punctuation gimmicks. Personalization is non-negotiable: emails that reference the recipient's company, role, or a recent event see 2-3x higher reply rates than generic templates.

The Anatomy of a High-Performing Cold Email

A strong cold email follows a simple structure: a personalized opening line that shows you did your research, one or two sentences about a relevant problem you can solve, a brief mention of credibility (social proof, results, or a case study), and a low-friction call-to-action. The CTA should be a question, not a demand. "Would you be open to a 15-minute call this week?" outperforms "Schedule a demo now" every time.

Spam words are a silent killer. Words like "free", "guarantee", "limited time offer", and "act now" trigger spam filters and instantly erode trust. Even if your email reaches the inbox, these words signal a mass marketing blast rather than a genuine 1-to-1 message. Our grader flags every spam trigger word in your email so you can replace them with natural language.

Why Readability Matters in Cold Outreach

Busy executives scan emails in seconds. If your email reads like an academic paper, it gets deleted. The best cold emails are written at a 5th to 8th grade reading level with short sentences, simple words, and plenty of white space. Use line breaks between paragraphs, avoid jargon, and write the way you would speak in a casual business conversation.

Cold Email Best Practices Checklist

  • Keep your email between 50-150 words for optimal reply rates
  • Personalize the first line with the recipient's name, company, or a relevant detail
  • Use a subject line of 3-8 words without ALL CAPS or excessive punctuation
  • End with a single, low-friction question as your call-to-action
  • Remove all spam trigger words and keep sentences under 20 words

Frequently Asked Questions

Our cold email grader analyzes your subject line and email body across multiple dimensions: length, personalization, spam word detection, CTA strength, readability, and question usage. Each factor is scored individually and combined into an overall grade from A to F.
What makes a good cold email?
A good cold email has a short subject line (3-8 words), is between 50-150 words, includes personalization (company name, role, industry references), has a clear single call-to-action, avoids spam trigger words, and reads at an 8th-grade level or below.

How can I improve my cold email score?
Focus on the checks that failed: shorten your email to under 150 words, add personalization tokens like the recipient's name or company, remove spam words (free, guaranteed, limited time), add a clear question-based CTA, and simplify your language to a conversational tone.
