Cold email
The Cold Email Checklist: 23 Checks Before You Hit Send
August 11, 20267 min readUpdated August 17, 2026
Most cold emails fail for boring, fixable reasons: wrong person, zero relevance, a wall of text, or a sender domain that's already flagged. Run every campaign through these 23 checks before you send, and the ones that survive will outperform campaigns you'd have sent a month ago.
Before you write (1–3)
- Clear goal: you know whether this email should earn a reply, book a call, or ask for an intro — and you've written for that single outcome.
- One message per contact: you're not asking for a call AND a demo AND a referral in the same email.
- Sequenced follow-ups planned: you know what happens if they reply, ignore, or bounce.
Targeting (4–7)
- Right person: the recipient has the problem you solve and the budget to act on it.
- Right company: the account fits your ideal customer profile, not just your list.
- Right time: you're reaching out when the trigger exists — a new role, new funding, a public growth push.
- Verified contact: the email address is deliverable and the person is still in that role.
Subject line (8–11)
- Under 50 characters: it doesn't truncate on mobile and it doesn't look like a template.
- No spam triggers: no FREE, no ALL CAPS, no emoji overload, no 'Re:' or 'Fwd:' fakery.
- Specific, not clever: a reference to their company or situation beats wordplay every time.
- Honest: the subject promises exactly what the email delivers.
The body (12–17)
- Opener is about them: a specific, current observation — not 'I hope this finds you well'.
- One idea only: the email makes a single point a reader can grasp in five seconds.
- Relevance is explicit: it's clear why this matters to them, not just why it matters to you.
- Proof, not claims: one specific outcome, customer, or number instead of adjectives.
- Short: under 150 words. If it's longer, cut the sentence that defends the product instead of helping them.
- Scannable: short paragraphs, no wall of text, no bolded begging.
CTA and signature (18–20)
- One clear ask: a low-friction question ('Worth a 15-minute look?' beats 'Let's schedule a demo').
- Easy to say yes to: you've removed every step between their reply and your calendar.
- Professional signature: name, role, company, and a working link — and your outbound address is a person, not sales@noreply.
Sending rules (21–23)
- Volume is safe: you're not blasting your domain past a few hundred per day before it's warmed up.
- Bounces are handled: hard bounces are removed immediately so your reputation doesn't bleed.
- Unsubscribes honored: one click, instantly — deliverability and law both demand it.
What to do with the survivors
An email that passes all 23 checks is ready to send — but sending is where the work starts. Track opens, replies, and meetings per variant, kill whatever underperforms, and double down on the angles that earn replies. The checklist keeps you consistent; the data tells you what to change.
If the targeting half feels like the bottleneck, that's where research tools earn their keep — surfacing the companies in motion and the right person to contact is the difference between a list and a pipeline.
Frequently asked questions
How long should a cold email be?+
Under 150 words. If it's longer, cut the sentence that defends the product instead of helping the reader — one idea, scannable paragraphs, and a single low-friction ask.
What should you check before sending a cold email?+
Run the 23 checks: the right person at the right company, a specific subject line under 50 characters with no spam triggers, one clear idea with explicit relevance, verified contacts, and sending rules (volume, bounces, unsubscribes) that protect your domain.
What is a good cold email reply rate?+
It varies by industry, but replies are the only metric that means the email worked — track reply rate per variant and segment, kill whatever underperforms, and double down on the angles that earn responses.
