Beyond Opens: Choosing the Right KPIs for Email Deliverability & Deal Flow

Beyond Opens: Choosing the Right KPIs for Email Deliverability & Deal Flow

A jargon-free scorecard for business brokers who want email to drive more mandates

1. Why “Open Rate” Isn’t the Whole Story

For years, brokers gauged outreach success by one number: open rate - the percentage of recipients who appear to open your email. How is an “open” detected? Most email tools insert a tiny, invisible image inside each message; when that image loads, the system counts an open. But today:

  • Apple Mail Privacy Protection (MPP) pre-loads those images for its users, inflating your open count even when no one reads the message.
  • Outlook desktop often blocks images entirely, so real opens never get recorded.

Result: the same message could show a 60% open rate in Apple-heavy lists and 15% in Outlook-heavy lists - without any difference in owner interest.

Good news: open rate is still a useful starting point - but only if you pair it with smarter metrics that reveal what actually drives conversations and mandates.

2. Open Rate - Pros, Cons & Reality Check

What It Does WellWhere It Misleads
• Fast health signal - sudden drop flags a deliverability issue.• Apple MPP inflates opens by 10-30%.
• Helps compare subject-line tests in A/B campaigns.• Image blocking on Outlook desktop hides genuine opens.
• Easy to pull from any ESP (Apollo, HubSpot, Gmail add-ons).• Zero insight into engagement - did they read, reply, or act?

Rule of thumb: Open rate below 15% often points to spam-folder placement. Above 60% may be an Apple-inflated mirage. The sweet spot for clean cold outreach is 25–45%.

3. KPIs That Matter More for Brokers - and How to Measure Them

KPIWhy It MattersHow to Track It (No IT Degree Required)Healthy Range
Reply RateA direct signal that owners engaged - and the strongest positive reputation boost in Gmail/Outlook.1. Tag all outbound folders “Sent - Cold” in Gmail/Outlook.
2. Use your platform’s answered column (Apollo, Instantly, HubSpot) to divide replies by delivered sends.
3. Analyst3 auto-captures thread IDs and calculates in real-time.
Cold: 2%+
Warm: 8%+
Spam-Complaint RateFilters throttle at 0.3%; even 0.1% slows inbox placement.1. Open Gmail Postmaster → Spam Rate graph.
2. In Outlook, enable the Junk Email Reporting add-in to see counts.
3. Divide complaints by delivered messages for the period.
≤0.1%
Inbox Placement %Tells whether mail lands in Primary, Promotions, or Spam - far clearer than opens.1. Send a test to a seed list (GlockApps, InboxRepair).
2. View placement report - counts each folder per provider.
3. Analyst3 schedules seed tests twice a month and flags drops.
≥85% Primary/Inbox
First-30-Second Dwell TimeGmail notes if an email stays open ≥30s - proxy for genuine reading.1. In Apollo/HubSpot, export open-event timestamps.
2. Compare open vs. second event (scroll, link click) within 30s.
≥50% of opens
Bounce RateHigh hard-bounces tank reputation and signal list decay.1. ESP dashboard → “Hard Bounces.”
2. Divide by total sends.
3. Auto-remove hard-bounce addresses after each campaign - built into Analyst3.
≤2%

Real-world proof: A Canadian brokerage using Analyst3 swapped stale copy, pruned bounces, and A/B-tested email scripts. Reply rate climbed from less than 1% to 11% in ~7 weeks.

4 • Building a Simple KPI Dashboard (No IT Degree Needed)

ToolMetric PulledHow Often
Gmail PostmasterSpam-complaint %, domain reputationWeekly
Apollo / InstantlyOpens, replies, soft/hard bouncesDaily
GlockApps Seed TestsInbox placement %Bi-weekly

Prefer not to juggle log-ins? Analyst3 pipes these feeds into a single traffic-light dashboard (green = good, yellow = investigate, red = pause).

5. Action Triggers - When to Fix vs. When to Celebrate

TriggerImmediate Action
Open rate ↓ 10 pts over 48 hrsRun an inbox-placement test; check SPF/DKIM alignment.
Spam-complaint rate ≥0.3%Pause sequence; remove non-responders; rewrite copy.
Reply rate ≤ 1% after 300 sendsRefresh subject + preview; test a new CTA.
Inbox placement <80%Lower daily volume for a week; warm secondary domain.

6. Pulling It All Together

Open rate starts the conversation, but reply rate, spam-complaint % and inbox placement finish it. Monitor this trio and you’ll catch problems early, keep filters happy, and spend more time on qualified seller calls - less on guesswork.

Need the heavy lifting done for you? Analyst3 sets thresholds, surfaces alerts, and auto-adjusts sending pace so your deal flow stays on track.

Conclusion

Think of opens as looking through the storefront window; meaningful KPIs tell you who walked in, chatted, and bought. Shift your focus, and your email channel becomes a predictable engine for new mandates.
