Email Marketing Engine
Complete methodology for building, running, and optimizing email marketing — from domain setup to revenue attribution. Covers lifecycle email (newsletters, onboarding, retention) AND cold outreach (prospecting, personalization, follow-up). No API keys, no paid tools required.
Phase 1: Infrastructure & Deliverability
Domain Authentication Checklist
Before sending a single email, complete ALL of these:
domain_auth:
spf:
record: "v=spf1 include:_spf.google.com include:[esp-domain] ~all"
check: "nslookup -type=txt yourdomain.com"
status: pending # pending | configured | verified
dkim:
selector: "google" # or ESP-specific
key_length: 2048 # minimum
status: pending
dmarc:
policy: "v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com; pct=100"
progression: "none → quarantine → reject (over 4 weeks)"
status: pending
bimi:
logo_format: "SVG Tiny 1.2"
vmc_certificate: false # optional but increases trust
reverse_dns: pending
custom_return_path: pending
Domain Warm-Up Schedule
New domain or IP? Follow this exactly:
| Week | Daily Volume | Target Audience | Content Type | |------|-------------|-----------------|--------------| | 1 | 20-50 | Known engaged contacts | Personal, high-value | | 2 | 50-150 | Recent subscribers | Welcome + best content | | 3 | 150-500 | Active segment (opened 30d) | Mix of content types | | 4 | 500-1500 | Broader active list | Regular campaigns | | 5 | 1500-5000 | Full active list | Normal operations | | 6+ | Scale 20%/week | Full list minus unengaged | All campaign types |
Warm-up rules:
Sender Reputation Monitoring
Check these weekly:
reputation_dashboard:
google_postmaster:
domain_reputation: high # high | medium | low | bad
spam_rate: 0.02% # must stay under 0.1%
authentication: pass
encryption: tls
blacklists:
check_url: "https://mxtoolbox.com/blacklists.aspx"
listed_on: [] # any listing = immediate action
bounce_tracking:
hard_bounces: 0.3% # remove immediately, never re-send
soft_bounces: 1.2% # retry 3x, then suppress
complaint_rate: 0.04% # above 0.1% = emergency
inbox_placement:
gmail: 94%
outlook: 91%
yahoo: 88%
corporate: 85%
Emergency response if reputation drops: 1. Immediately reduce volume by 75% 2. Send ONLY to most engaged segment (opened in 7 days) 3. Pause all cold outreach and promotional campaigns 4. Review last 5 campaigns for content triggers 5. Check for spam trap hits (sudden bounces from old addresses) 6. Rebuild gradually over 2-4 weeks
Phase 2: List Building & Management
List Growth Strategy
Organic growth methods (ranked by quality):
| Method | Quality | Volume | Setup Effort | |--------|---------|--------|-------------| | Content upgrade (in-article) | ★★★★★ | Medium | Medium | | Webinar/event registration | ★★★★★ | Low-Med | High | | Free tool/calculator | ★★★★☆ | High | High | | Newsletter referral program | ★★★★☆ | Medium | Medium | | Exit-intent popup | ★★★☆☆ | High | Low | | Social media bio link | ★★★☆☆ | Low | Low | | Co-marketing swap | ★★★☆☆ | Medium | Medium | | Gated whitepaper/report | ★★★☆☆ | Medium | Medium | | Contest/giveaway | ★★☆☆☆ | High | Medium | | Purchased list | ☆☆☆☆☆ | High | Low |
Never buy lists. Purchased lists contain spam traps, kill deliverability, and violate GDPR/CAN-SPAM. The "shortcut" costs more than building organically.
Lead Magnet Framework
Every opt-in needs a compelling reason:
lead_magnet:
name: "[Specific Outcome] [Format]"
format: checklist | template | calculator | swipe_file | mini_course | report
promise: "What specific result will they get?"
time_to_value: "< 5 minutes" # faster = higher conversion
quality_bar: "Would someone pay $20 for this?"
delivery: immediate # never gate behind "check your email in 24h"
# Opt-in page elements
headline: "[Number] [Outcome] without [Pain]"
subhead: "One specific proof point or social proof"
bullet_1: "Specific benefit with number"
bullet_2: "Addresses main objection"
bullet_3: "Speed/ease promise"
form_fields: [email] # name optional, more fields = lower conversion
cta_button: "Get the [Format]" # never "Submit"
social_proof: "[X] people downloaded this week"
Segmentation Architecture
Core segments (minimum viable):
segments:
lifecycle:
- new_subscriber:
definition: "Joined < 14 days ago"
treatment: "Welcome sequence, daily for 2 weeks"
- active:
definition: "Opened or clicked in last 30 days"
treatment: "Full campaigns, all content types"
- cooling:
definition: "No opens 30-60 days"
treatment: "Reduced frequency, best content only"
- dormant:
definition: "No opens 60-90 days"
treatment: "Re-engagement sequence"
- dead:
definition: "No opens > 90 days, re-engagement failed"
treatment: "Remove from list (improves deliverability)"
- customer:
definition: "Has purchased"
treatment: "Retention, upsell, referral"
- vip:
definition: "Top 10% by engagement OR revenue"
treatment: "Early access, exclusives, personal touch"
behavioral:
- clicked_pricing: "Sales-ready, trigger demo offer"
- downloaded_resource: "Interested in [topic], nurture there"
- visited_3x_week: "High intent, accelerate sequence"
- opened_not_clicked: "Subject works, content needs help"
- clicked_not_converted: "Interest without action, address objection"
demographic:
- by_role: "[CEO, VP, Manager, IC]"
- by_company_size: "[1-10, 11-50, 51-200, 201-1000, 1000+]"
- by_industry: "[SaaS, Ecommerce, Finance, Healthcare, etc.]"
List Hygiene Protocol
Run monthly:
List Hygiene Checklist:
□ Remove all hard bounces (immediately, never re-add)
□ Suppress soft bounces with 3+ consecutive failures
□ Remove spam complainers (permanent suppress)
□ Flag role addresses (info@, admin@, support@) — lower priority
□ Identify spam traps (sudden old-domain bounces)
□ Run email verification on new imports (NeverBounce, ZeroBounce)
□ Sunset dormant subscribers (90 days no engagement)
□ Merge duplicates (same email, different entries)
□ Update preference center opt-outs
□ Document list size change: [before] → [after] = [% change]

Cold Outreach Sequence (5 emails, 21 days)
For prospects who don't know you:
cold_outreach:
principles:
- "Research before writing — generic = spam"
- "One ask per email — never multiple CTAs"
- "Under 125 words — busy people skim"
- "No HTML, no images — plain text performs 2x better"
- "Personalize first 2 lines or don't send"
- "Never lie about prior relationship ('We met at...' when you didn't)" email_1:
timing: "Day 0"
subject: "[First name], quick question about [their specific initiative]"
template: |
Hi [Name],
Saw [specific thing — blog post, LinkedIn update, company news, job posting].
[One sentence connecting their situation to your value prop].
We helped [similar company] [specific result with numbers].
Worth a 15-min call to see if this applies to [their company]?

[similar company] from [before] to [after].
Open to hearing them?

note: "Show you've done homework — specific observation > generic pitch"
email_4:
timing: "Day 14"
subject: "Should I close the loop?"
template: |
Hi [Name],
I've reached out a few times — totally understand if the
timing isn't right.
If [problem you solve] isn't a priority right now, no worries.
But if it is, I'd love 15 minutes to share what's working
for [industry] companies like [their company].
Either way, just let me know and I'll update my notes.

timing: "Day 21"
subject: "Closing the file on [their company]"

Re-Engagement Sequence (3 emails)
For subscribers going dark (30-90 days no opens):
re_engagement:
email_1:
timing: "Day 0 (triggered at 60 days no open)"
subject: "Still interested in [topic]?"

cold_email_rules:
domain:
- "Use a separate domain for cold outreach (not your main domain)"
- "Set up: outreach.yourdomain.com or yourdomain.co"
- "Full SPF/DKIM/DMARC on the outreach domain"
- "Warm up for minimum 2 weeks before sending"
volume:
- "Maximum 50 cold emails per day per inbox"
- "Use multiple inboxes to scale (5 inboxes = 250/day)"
- "Spread sends throughout the day (not all at once)"
- "Randomize send times ±15 minutes"
content:
- "Plain text only — no HTML, no images, no tracking pixels"
- "Under 125 words (3-4 short paragraphs)"
- "No more than 1 link per email"
- "Avoid spam trigger words (free, guaranteed, act now, limited)"
- "Include physical address and opt-out mechanism"
list:
- "Verify every email address before sending (< 3% bounce)"
- "Never send to catch-all domains without verification"
- "Remove any email that bounces immediately"
- "Respect unsubscribe within 24 hours"
Reply Handling Framework
reply_handling:
positive:
signals: ["interested", "tell me more", "let's talk", "send info"]
response_time: "< 1 hour during business hours"
action: |
1. Thank them specifically for what they said
2. Answer any questions in the reply
3. Propose 2-3 specific meeting times
4. Keep it short — they said yes, don't oversell
objection:
signals: ["too expensive", "not now", "using competitor", "not interested"]
response_time: "< 4 hours"
action: |
1. Acknowledge their concern genuinely
2. Address the specific objection (not a generic rebuttal)
3. Offer lighter alternative (case study, free resource)
4. Leave door open: "If things change, I'm here"
referral:
signals: ["talk to [name]", "not the right person", "try [department]"]
action: |
1. Thank them warmly
2. Ask: "Would you mind making an intro, or should I reach out directly and mention you?"
3. Reference the referral in new outreach
negative:
signals: ["remove me", "stop emailing", "spam", "unsubscribe"]
action: "Immediately suppress. Reply with brief apology. Never re-add."

good: "Monday 7AM, Thursday 4PM"
avoid: "Weekends, lunch hour, Friday PM"
advanced:
- "Use ESP's send-time optimization if available"
- "Test YOUR audience — benchmarks are averages, not your data"
- "Consider timezone — segment by geography for large lists"
- "Account for industry patterns (retail ≠ enterprise ≠ healthcare)"

Revenue Attribution Model
attribution:
last_touch:
description: "Credit to last email before conversion"
use_when: "Simple tracking, small list, direct sales"
first_touch:
description: "Credit to email that acquired the subscriber"
use_when: "Measuring list-building ROI"
linear:
description: "Equal credit to all emails in journey"
use_when: "Understanding full funnel contribution"
time_decay:
description: "More credit to emails closer to conversion"
use_when: "Mature program with long sales cycles"
calculation: |
Email ROI = (Revenue attributed to email - Email costs) / Email costs × 100
Email costs include:
- ESP subscription
- Email verification tools
