How to Improve Each Metric
Deliverability
Problem: Below 90%
- → Warm up your email domain before sending at volume
- → Verify email addresses before sending (removes bounces)
- → Use a dedicated sending domain, not your main domain
- → Authenticate with SPF, DKIM, and DMARC
Open Rate
Problem: Below 25%
- → Test subject lines (questions outperform statements)
- → Personalize the first line visible in preview
- → Send from a real person's name, not a company
- → Experiment with send times (Tuesday-Thursday, 9-11 AM)
Reply Rate
Problem: Below 3%
- → Lead with value, not your product
- → Keep emails under 100 words
- → Use personalized video messages
- → Reference something specific about them
Positive Reply Rate
Problem: Below 30%
- → Better qualify your list (are these actually your ICP?)
- → Adjust your offer (too aggressive? too vague?)
- → Test different value propositions
- → Review timing (are you catching them at the right moment?)
Show Rate
Problem: Below 75%
- → Send calendar invites immediately after booking
- → Add reminder sequences (24h and 1h before)
- → Make rescheduling easy (include reschedule link)
- → Confirm by phone the day before
