Email open rate	20-40%	50%	60%+
Email click rate	2-5%	5-8%	10%+

Performance by Outreach Type

Outreach Type	Reply Rate
Cold outreach (no signal)	6-8%
Signal-based outreach	18-22%
Multi-signal stacked	35-40%
Website visitor follow-up	25-30%
Champion job change	20-25%

Email Structure Checklist

Opening (trigger) + Assumption + Social proof with numbers + Open-ended question

By Seniority

Target	Max Sentences	Max Words
BTL (Managers, ICs)	3-4 sentences	90 words
ATL (VPs, C-Level)	2-3 sentences	60 words

Deliverability Benchmarks

Metric	Target	Warning	Critical
Bounce rate	<2%	2-5%	>5%
Spam rate	<0.1%	0.1-0.3%	>0.3%
Unsubscribe rate	<0.5%	0.5-1%	>1%

Sequence Performance

Email 1

Highest open rate
Sets the tone
Most important to optimize

Email 2 (Day 3)

40-60% of Email 1 opens
Different angle
Shorter than Email 1

Email 3 (Day 14)

New subject line
Fresh approach
Delegation ask effective

Email 4 (Break-up)

Often highest reply rate
Creates urgency
Clean exit

Optimization Priorities

If Open Rate Low (<30%)

Test subject lines
Check sender reputation
Verify deliverability
Test send times

If Reply Rate Low (<2%)

Improve relevance/personalization
Shorten message
Strengthen CTA
Add social proof
Test different frameworks

If Meeting Rate Low (<20% of replies)

Qualify better in message
Improve CTA clarity
Reduce friction to book
Follow up faster

Quick Diagnostics

Symptom	Likely Cause	Fix
Low opens	Subject line or deliverability	A/B test subjects, check spam score
Opens but no replies	Message relevance	More personalization, shorter copy
Replies but no meetings	Weak CTA or poor qualification	Clearer ask, better targeting
High unsubscribe	Too aggressive or wrong ICP	Reduce frequency, refine targeting
