[Similar Company] was [specific situation]. In just [timeframe], they:

The best part? They got started in under [timeframe] without [common objection].

Would [Day] at [Time] work for 15 minutes?

[Your Name]

Email #3: The Different Angle

Subject: "Different thought about [their company]"

Hi [First Name],

I realize [original pain point] might not be top of mind right now.

But what about [alternative pain point]?

Most [their role]s say [common complaint], which is why [mini value prop].

If this hits closer to home, happy to share how [quick win].

[Your Name]

P.S. - If neither is relevant, just let me know and I'll stop!

No ask here—just sharing something helpful:

Email #6: The Direct Ask

Subject: "Let's cut to the chase"

[First Name],

Let me be direct: I think we could help [their company] [achieve outcome] based on [observation].

I'd like to show you:
1. [Specific thing #1]

15 minutes. No pressure. How's [specific day/time]?

[Your Name]
[Phone number]

Email #7: The Breakup

Subject: "Should I close your file?"

[First Name],

I'll assume [topic] isn't a priority right now—totally fine.

I'll close your file unless I hear otherwise. For what it's worth, we see best results when [time-sensitive reason], so if you want to revisit, might be worth a quick chat now.

No worries either way—appreciate your time.

[Your Name]

P.S. - If someone else at [their company] should hear about this, happy to redirect.

Breakup Variations:

• FOMO: "Taking you off the list. FYI—[competitor] just started and is seeing [early result]."
• Permission: "Assuming this is: 1) Not relevant, 2) Not priority, 3) Bad timing. Which? If #3, when should I check back?"
• Referral: "Clearly I'm not reaching the right person. Should I talk to someone else about [topic]?"

A/B Testing Strategy

Test Priority (in order):

1. Subject Lines: Question vs. Statement, Generic vs. Personalized, Short vs. Long
2. Email Body: Length (50 vs. 100 words), CTA style (Link vs. Question vs. Time slot)
3. Send Time: Morning vs. Afternoon, Tue vs. Wed vs. Thu

Method: Send to 100 prospects (50/50 split), wait 48 hours, measure open + reply rates, winner goes to remaining list.

Performance Benchmarks

Segmentation

Adjust sequences by Industry (swap case studies, use industry terminology), Company Size (Startup: ROI focus; Mid-Market: scalability; Enterprise: security/compliance), Role (Executive: strategic outcomes; Practitioner: time savings; Technical: architecture/specs), and Intent (Hot: shorter/faster; Warm: standard 7-email; Cold: longer nurture).

Quick-Start Templates

SaaS Sales: Question about growth metric → Competitor case study → Alternative pain → Mutual connection → Free benchmark report → 15-min demo → Close file

Agency/Services: Recent achievement → Client case study → Quick idea for challenge → Competitor approach → No-strings audit → 15-min call → Bad timing?

Partnership: Mutual contact intro → Win-win opportunity → Similar partner example → Partnership program question → Worth exploring?

Pro Tips

1. 3-Second Rule: Prospect should understand value in first 3 seconds
2. One CTA Only: Don't give multiple options
3. Mobile-First: 50%+ opened on mobile; keep scannable
4. No Attachments: Use links; attachments trigger spam filters
5. The P.S. Works: PostScripts get read; use for secondary CTA
6. Follow-Up Matters: 80% of responses come from emails 3-7

Pre-Launch Checklist

• Sender email has good deliverability (SPF, DKIM, DMARC)
• Email warmed up (sent successful emails recently)
• List cleaned (no invalid emails)
• Personalization variables all filled
• Links tested and tracked
• CRM integration working
