How to write a cold email that gets replies
A cold email gets replies when it is short (under 120 words), opens with a specific reason you are writing, states one line of value the reader cares about, and ends with a single easy ask. Relevance beats cleverness: a message tied to a real trigger or detail outperforms a polished generic pitch every time. This guide breaks down the structure, subject lines, personalization, deliverability, and follow-up, with examples you can copy.
The four-part structure
Every cold email that gets a reply has the same four parts, in this order. Miss one and the email falls flat. It is less a creative-writing task than assembling four components correctly.
- 1A relevant hook: The first line proves you did your homework: a trigger event, a detail from their profile, a mutual connection. Never "Hi, hope you're well."
- 2One line of value: State the single thing the reader cares about, in their terms. One outcome, not a feature list.
- 3One specific ask: Ask for exactly one thing. Two asks means zero replies.
- 4An easy next step: Make saying yes take one word or one click: a time, a link, a simple question.
The structure in action
Hi Sarah, Saw Acme just closed your Series A. Congratulations. [hook: a real, timely trigger] Teams usually double the sales headcount right after a raise, and new reps take 60+ days to ramp. We cut that to about 30 for companies like Beta Co. [value: one outcome they care about] Worth a quick look before you hire the next five? [one easy ask]
Strip the annotations and that is a complete cold email in under 60 words. Every sentence earns its place.
Keep it under 120 words
Most cold emails are read on a phone in a few seconds. If your ask is buried in the third paragraph, it never gets seen. Shorter, more specific emails consistently beat longer ones, on both reply rate and sender reputation.
A useful test: if you cannot read your email aloud in under 15 seconds, it is too long. Cut everything that is not the hook, the value, or the ask. Adjectives, throat-clearing, and background go first.
Write subject lines that get opened
No open, no reply. The best cold email subject lines are short (two to five words), lowercase or sentence case, specific to the recipient, and free of anything that looks like marketing.
| Angle | Example | When to use |
|---|---|---|
| Curiosity | quick question, Sarah | No personal hook yet, but a useful angle inside |
| Personalized | your post on SDR ramp | You did real research |
| Trigger | congrats on the round | Something happened this week |
| Direct | 15 minutes, Sarah? | Strong, specific value prop |
| Referral | Alex suggested I reach out | You have a mutual connection |
Avoid title case, exclamation marks, all caps, and words like free, guarantee, or act now. Spam filters and human readers flag the same signals. Write the subject as if you were emailing a colleague.
Personalize the hook, template the rest
Full personalization does not scale, and fully templated emails do not convert. The answer is to personalize the one line that matters, the hook, and template the rest. That gives you relevance without spending an hour per email.
- Merge fields for the basics: Name, company, role. These are table stakes and should never be wrong.
- Manual effort for the hook: One genuinely specific opener per email, drawn from a trigger, a post, or a detail.
- Video for the personalization: A short personalized video carries the personalization for you while feeling one-to-one, and lifts replies about 2.7x in our data.
Protect your deliverability
A perfect email fails if it lands in spam. Deliverability is decided largely before you hit send, by your domain reputation, your authentication records, your sending volume, and your content.
The deliverability checklist
- Authenticate your domain: Set up SPF, DKIM, and DMARC records. Without them, providers distrust your mail by default.
- Warm up new domains: Ramp volume gradually over days and weeks. A new domain that immediately blasts hundreds of emails looks exactly like a spammer.
- Verify addresses before sending: High bounce rates wreck sender reputation fast. Send only to verified emails.
- Keep volume reasonable: Do not send more than a healthy sender would. Split volume across inboxes if needed.
- Clean content: Few links, no spam-trigger words, real plain-text feel.
Verifying email addresses is one of the simplest ways to protect deliverability. Weezly's leads database only exports verified emails, which keeps bounce rates low and your reputation intact.
Follow up, because most replies come later
A large share of cold replies come from follow-ups, not the first email. The mistake is either giving up after one touch, or bumping the same message over and over. Each follow-up should add something new.
| Touch | Day | Angle |
|---|---|---|
| 1 | 1 | First email: hook, value, ask |
| 2 | 4 | Gentle bump on the same thread |
| 3 | 8 | Fresh angle: a trigger or new insight |
| 4 | 11 | Proof: a similar company's result |
| 5 | 14 | Shrink the ask: a two-minute video, no call needed |
| 6 | 18 | Break-up: assume it is not the right time |
End with the break-up email. It often gets the highest reply rate of the sequence, because the easy out feels like relief and people hate to lose something they might have wanted.
Add video to cold email
The single biggest format lever on reply rate is video. A short personalized video, embedded as a clickable thumbnail in the email, stands out in a text-only inbox and proves a real person is reaching out.
The scale problem is the same as everywhere: you cannot record one per prospect by hand. Weezly clones your face and voice from one recording and generates a personalized video per prospect, with a booking page under each so an interested reader can schedule in one click.
Common cold email mistakes
- Talking about yourself first: The reader cares about their problem, not your company. Lead with them.
- Too long: If the ask is not near the top, it never gets read.
- Vague or multiple asks: "Let me know your thoughts" is not an ask. Give one clear, easy next step.
- No follow-up: Sending once and moving on leaves most of your replies on the table.
- Ignoring deliverability: Great copy in the spam folder gets zero replies. Warm up, authenticate, verify.
Frequently asked
How long should a cold email be?
Under 120 words. Cold emails are skimmed on mobile in seconds, so if your ask is not near the top it never gets read. Shorter, more specific emails consistently get more replies.
What is a good cold email reply rate?
It varies widely by list quality and targeting, but strong, well-targeted campaigns often see reply rates in the high single digits to low double digits. Adding a personalized video is one of the biggest levers, lifting replies about 2.7x in our data.
How many follow-ups should a cold email sequence have?
Four to six touches total, including the first email, each adding a new angle. Space them three to five business days apart and end with a break-up email rather than sending endless reminders.
How do I stop my cold emails landing in spam?
Authenticate your domain with SPF, DKIM, and DMARC, warm up new domains gradually, verify addresses before sending to keep bounce rates low, keep volume reasonable, and avoid spammy content. Deliverability is decided mostly before you hit send.
Is cold email or LinkedIn better for outreach?
Neither alone: the best results come from combining them in one coordinated sequence. Reaching a prospect on both LinkedIn and email, with the touches referencing each other, consistently outperforms a single channel.
