The Hybrid Approach (Best ROI)
How I use both together:
Step 1: Cold email first (Days 1-14)
- Send personalized email
- 3 follow-ups over 14 days
- Track opens and clicks
Step 2: Call engaged prospects (Day 15)
- Call everyone who opened 2+ times
- Call everyone who clicked
- Reference the email: "Following up on the email I sent..."
Step 3: LinkedIn touch (Day 20)
- Send connection request
- Mention email and call attempt
Results with hybrid:
- 7.8% meeting booking rate (vs 4.1% email-only, 2.3% call-only)
- $89 cost per meeting (vs $127 email, $284 calling)
- Best of both worlds
