Cold Emailing
Subject lines, structure, sequences, deliverability, templates.
The email that gets a reply
Cold email is a written cold call — same job, different medium. The best prospecting emails share four traits: short, specific, about the prospect, and easy to respond to. Everything else is optional. If a prospect can screenshot your email and it fits on one phone screen, you're close.
Structure of a cold email
- Subject line — 3–6 words, lowercase, no title case, no emojis.
- Opener — one line of relevant personalization (not "loved your post").
- Body — 2–3 sentences on the pain and the outcome.
- Social proof — one line, one comparable customer, one specific result.
- CTA — one question the prospect can answer in a single word.
Subject lines that work
- quick idea for [team]
- [Company] + [Your Company]?
- {first name}, worth 30 seconds?
- [Competitor] vs [Your Company]
- 3 questions on [initiative]
Avoid ALL CAPS, exclamation marks, spammy words ("free", "guaranteed", "urgent"), and anything that reads like a newsletter blast.
Personalization at scale
"Loved your recent post!" is not personalization. Real personalization ties an observation about the prospect or their company to the problem you solve. Three tiers of reference from cheapest to strongest:
- Trigger: hiring signal, funding round, product launch, exec change.
- Tech signal: they use tool X and Y — a known integration pain.
- Human signal: a specific quote from a podcast, earnings call, or LinkedIn post.
Use tools like Clay to enrich a list of 500 accounts with 2–3 trigger fields, then batch-write per-segment templates. This gets you 80% of manual personalization at 10% of the effort.
Follow-up sequences
The first email closes 5–15% of the eventual replies. The rest come from the sequence:
| Day | Channel | Purpose |
|---|---|---|
| 0 | Email #1 | Personalized opener + pain hook + CTA |
| 2 | LinkedIn view + connect (no note) | Warm the account |
| 3 | Call attempt | Real conversation |
| 5 | Email #2 | New angle — different pain, same outcome |
| 8 | Call + voicemail + email | Triple touch |
| 11 | Email #3 | Customer proof / case study |
| 15 | LinkedIn message | Soft nudge |
| 21 | Break-up email | "Should I close the loop?" |
Deliverability basics
A perfectly written email that lands in spam is worthless. Every prospecting rep should understand the fundamentals:
- SPF (Sender Policy Framework): a DNS record that says which servers are allowed to send from your domain.
- DKIM (DomainKeys Identified Mail): cryptographically signs outgoing mail so receivers can verify authenticity.
- DMARC: tells receivers what to do when SPF/DKIM fail. Set to at least
p=nonefor reporting. - Warm-up: new domains should be gradually ramped (50→100→200 emails/day over 4–6 weeks) with tools like Instantly or Smartlead.
- Send from a subdomain (e.g.
@go.company.com) so a spam hit doesn't torch your main domain. - No links or images in the first email. Both hurt inboxing dramatically.
5 templates you can steal
1. The trigger email
Subject: congrats on the Series B
{First} — saw the round close last week. Nice.
Most revops leaders we work with at post-Series-B SaaS companies hit the same wall around this stage: pipeline forecasts drift by 20–30% month over month because the CRM is behind. We fix that.
Worth 15 min next week to compare notes?
2. The pain-first email
Subject: 4 hours/week on pipeline reports?
{First} — a common pattern: revops at your stage burns 4–6 hours a week just cleaning CRM data for weekly forecast meetings. Sound familiar?
We cut that to zero for {Comparable Company}, and their forecast accuracy went from 68% to 91% in a quarter.
Open to a quick look?
3. The referral / permission email
Subject: right person at {Company}?
{First}, quick one — who owns pipeline reporting for the sales team these days? I have something specific and want to make sure I'm not wasting the wrong person's time.
Thanks in advance.
4. The competitor-switch email
Subject: {Competitor} vs. {Your Company}
{First} — noticed you're likely on {Competitor}. Half our new customers come from there, mostly because of {specific limitation}.
Not saying you should switch. Curious if that's a pain for you too — worth 10 minutes to compare?
5. The break-up email
Subject: should I close the loop?
{First} — I've reached out a few times without a reply, which usually means one of three things:
1. It's not a priority (fine).
2. It is, but the timing's wrong.
3. I've got the wrong person.
Just reply with 1, 2, or 3 and I'll act accordingly. Appreciate it.
Common mistakes
- Writing paragraphs. If the email doesn't fit on a phone screen, cut it.
- Pitching your product before understanding the pain.
- Asking for "15–30 minutes" — sounds long. Ask for 10 or 15.
- Sending on Monday morning or Friday afternoon. Aim for Tuesday–Thursday, 8am prospect local.
- Sending without warmup. New domains with no warm-up hit spam almost immediately.
Email is a numbers game with quality gates. Nail the fundamentals — copy, deliverability, sequence, list hygiene — and you'll book more meetings than peers doing twice the volume.
