Use campaign data to find where relevant prospects stop progressing. Change one part of the sequence at a time and measure qualified replies and meetings.
The Key Metrics
Track three categories of metrics: Activity (what you're doing), Response (how they react), and Outcomes (what matters).
Activity Metrics
- •Emails sent
- •Calls made
- •Connection requests sent
- •Touches per prospect
Response Metrics
- •Email open rate
- •Email reply rate
- •Call connect rate
- •LinkedIn acceptance rate
- •Overall response rate
Outcome Metrics
- •Meetings booked
- •Conversion rate (touch → meeting)
- •Pipeline generated
- •Revenue influenced
Benchmarks
Here's what "average," "good," and "great" look like for key sequence metrics:
Use a consistent test: compare the same audience and time period, record the effort spent, and evaluate qualified conversations and meetings. The right choice depends on the purpose of the message.
Pro Tip
Where to Look for Problems
Each metric problem points to a different root cause. Here's how to diagnose what's broken:
Low Open Rates
- • Subject lines not compelling enough
- • Sending at wrong times
- • Deliverability issues (check spam folder placement)
- • Wrong audience (bad list quality)
Low Reply Rates
- • Message not relevant to recipient
- • No clear value proposition
- • CTA too aggressive or confusing
- • Email too long
Low Connect Rates
- • Bad phone numbers / outdated data
- • Calling at wrong times
- • Not enough attempts per prospect
- • No voicemail strategy
Low LinkedIn Accept Rate
- • Profile not optimized
- • Connection note too salesy
- • Targeting wrong persona
- • No mutual connections or context
A/B Testing Sequences
Systematic testing is how you improve. But test the right things in the right order.
Testing Priority (Biggest Impact First)
- 1.Subject lines — Biggest lever for open rates
- 2.Opening lines — Determines if they read further
- 3.CTA types — Interest-based vs calendar link
- 4.Send times — Test against a comparable audience
- 5.Number of touches — Find diminishing returns
Do This
- Test one variable at a time
- Minimum 100 sends per variant
- Run for at least 2 weeks
- Document all tests and results
Avoid This
- Change multiple things at once
- Declare winners too early
- Test trivial differences
- Forget to roll out winners
Analyzing by Touch Number
Not all touches perform equally. Understanding which touches drive responses helps you optimize or eliminate underperformers.
Questions to Answer
- →Which touch number gets the most responses?
- →Where do most people drop off (stop opening)?
- →Is your break-up email working? (Should spike responses)
- →Are late touches (7+) worth the effort?
The data shows diminishing returns but cumulative value. Each touch performs worse than the last, but the total responses from touches 2-5 often exceed touch 1 alone.
Channel Attribution
In multi-channel sequences, it's often hard to know which channel "caused" the meeting. Use both last-touch and multi-touch attribution.
Last Touch Attribution
Which channel did they respond on? Phone often wins here, but email may have warmed them up.
Multi-Touch Attribution
Which channels did they engage with before responding? Often it's email opens + LinkedIn view + phone answer.
Pro Tip
The Optimization Cycle
Sequence optimization isn't a one-time project. It's an ongoing cycle:
Run for 2-4 Weeks
Collect enough data to be statistically meaningful
Analyze Metrics
Compare to benchmarks, identify weakest points
Identify Weakest Touch
Find the touch with worst performance relative to its position
Test Improvement
Create A/B test for that specific touch
Measure Impact
Did the change improve overall sequence performance?
Roll Out Winner
Apply winning variant to all sequences
Repeat
Move to the next weakest touch
The best sequences are never "done." They're constantly measured, tested, and improved. Build this cycle into your process from day one.
Key Takeaways
- ✓Track activity, response, and outcome metrics
- ✓Define and measure held qualified meetings per contacted prospect
- ✓Test one variable at a time, minimum 100 sends
- ✓Subject lines are the biggest lever for improvement
- ✓First email gets highest reply rate, but later touches still matter
- ✓Optimization is a cycle, not a one-time project
