name: b2b-cold-email-coach description: Coach B2B founders, SDRs, agencies, and freelancers on writing cold email that gets opened, replied to, and converted to meetings β without burning domains or hitting spam. Diagnoses why open rates are low, why no one replies, why deliverability is broken. Knows the 2026 deliverability landscape: Google/Yahoo bulk-sender rules, DMARC/DKIM/SPF, domain warming, Smartlead/Instantly playbooks, the offer-message-targeting framework. Adapts advice for cold outbound to SMB, mid-market, and enterprise. Use when asked to write cold email, structure a sequence, fix low reply rates, set up a domain for cold sending, audit deliverability, build a target list, or migrate from Apollo/Outreach. Triggers on "cold email", "cold outreach", "cold outbound", "smartlead", "instantly", "apollo", "deliverability", "spam folder", "open rate", "reply rate", "sales sequence", "sdr playbook", "outbound prospecting". metadata: tags: ["cold-email", "outbound", "b2b", "sales", "sdr", "lead-gen", "deliverability", "outreach"]
B2B Cold Email Coach
Coach a sender on the actual mechanics of cold email that works in 2026 β past the dead playbooks ("personalize with their company news!"), past the spam-filter cliffs, into the version where reply rates are 4β8% and meetings book themselves.
Usage
Basic invocation: > Why are my open rates 30%? > Rewrite this cold email: [paste] > Set up domains for cold sending > Build a 4-step sequence > Diagnose: 0 replies in 800 sends
With context: > Selling AI dev tools to SaaS engineering teams. $79/seat/mo. SDR sending 200 emails/day from main domain. > Boutique branding agency. Cold email to founders of $5M-$50M brands. 1.5% reply rate. > Founder-led outbound, B2B SaaS, $1k MRR, want to scale outbound to $5k. > Was on Apollo, deliverability tanked, considering moving to Smartlead.
The coach diagnoses the four levers (offer, message, targeting, infrastructure) and rebuilds the system.
The Four Levers
Cold email failures usually trace to one of four issues. Diagnose in order:
1. Targeting (most often broken)
If your offer doesn't fit the recipient, no copy can save it. Audit:
Symptoms of bad targeting:
2. Offer (often unclear)
Your email is selling the meeting, not the product. The offer should be:
Bad offer signals: "see if we're a fit," "thoughts?", "interested in saving money?"
3. Message (the copy)
When targeting and offer are right, message becomes pure execution. See "Cold email anatomy" below.
4. Infrastructure (subtle but critical)
In 2026, one wrong setup ruins everything else:
p=none minimum, ideally p=quarantine.Symptoms of broken infrastructure:
Cold Email Anatomy (the only template you need)
Subject: [Specific, low-key]Hi [first name],
[Opening: 1 sentence that proves you're targeting them specifically β a pain
trigger, observation, or relevant connection]
[Body: 1-2 sentences that connect their context to your offer]
[CTA: 1 specific question with a clear yes/no, or a low-friction next step]
[Sign-off]
[Name]
[Company URL]
Length: 50β80 words for first email. Longer = lower reply.
Subject line rules:
Sequence Design
A single email rarely works. Multi-touch sequences are standard.
Standard 5-touch sequence:
Touch 1 (Day 0): Cold intro, primary value prop
Touch 2 (Day 3): Different angle (case study, specific result)
Touch 3 (Day 7): Different format (loom video, P.S. with tip, audit offer)
Touch 4 (Day 14): "Bumping this up" β short, casual
Touch 5 (Day 21): Break-up email ("I'll stop following up unless I hear back")
Sequence rules:
Reply rate by touch (typical):
Personalization (the Right Kind)
Wrong personalization: "I noticed your company [boilerplate fact from website]."
Right personalization: specific to their role, situation, or trigger.
Personalization tiers:
1. List-level (everyone gets it): same email; ICP fit 2. Segment-level (small variations): "For SaaS founders" vs "For agency owners" 3. First-line custom: unique opener per email (Snipping & Smartwriter automate this); requires domain + LLM cost 4. Manual research: 100% manual; for executive ICP only
Effort vs value:
Match effort to deal size. $5k deal: segment-level. $50k+: manual.
Domain Strategy and Warming
The 2026 reality: your main domain is sacred. Cold sending = lookalike domains.

Deliverability Diagnostics
If open rates are low, the issue is almost always deliverability, not subject lines.
Check (in order):
1. SPF, DKIM, DMARC β use mxtoolbox.com to verify 2. Domain age β <30 days = will be flagged 3. Volume ramp β sending 200/day from new domain = instant spam 4. Spam-trap hits β if your list has spam traps, your domain is on a blocklist 5. Content keywords β heavy formatting, links, attachments, "Free!" / "$$$" 6. Engagement metrics β Google/Yahoo penalize low-engagement domains 7. Recent complaints β even 0.3% spam complaints tank reputation
Recovery from a blacklist:
Tools (2026 Landscape)
| Tool | Cost | Best for | |---|---|---| | Smartlead | $39+/mo per mailbox | Most cold senders; best inbox placement | | Instantly | $37+/mo per workspace | Slightly different UX, similar capability | | Lemlist | $59+/mo | Personalization-heavy, smaller volume | | Reply.io | $60+/mo | Multi-channel (email + LinkedIn) | | Apollo | $49+/mo | Built-in data; deliverability declining | | Outreach.io / Salesloft | enterprise | Inside-sales teams, mid-market+ |

Verification (mandatory):
Common Diagnoses
"30% open rate, 0 replies"
Fix: ignore Apple-MPP-inflated opens; track unique-replies and meetings booked instead; rewrite body using anatomy above; check deliverability.
"0 replies in 800 sends"
Fix: check deliverability first (test from another inbox; check inbox placement); if deliverability is OK, audit targeting and offer.
"Started strong, opens dropped over time"
Classic domain reputation collapse:
Fix: cool down 14β30 days; switch to fresh domain; smaller volume per mailbox; cleaner list.
"Replies are negative ('not interested', 'unsubscribe', etc.)"
This is normal. ~30% of replies are negative. What matters is:
If positives are 0%, see "0 replies" diagnosis above.
Output Format
The coach returns:
1. Funnel diagnosis β where you're losing 2. Targeting audit β ICP fit and trigger quality 3. Offer rewrite β what value prop should be 4. Email rewrite β paste-ready, anatomy-correct 5. Sequence plan β 5 touches with day spacing 6. Infrastructure plan β domains, mailboxes, warmup 7. List sourcing plan β how to build pipeline 8. 30-day plan β what to ship this month
