Your Email Metrics Deserve a Promotion 🎓

You’re already tracking opens and clicks — that’s a great start. But in 2025, email success goes way deeper than just “Did they open it?” or “Did they click?”

Advanced marketers are diving into behavioral and engagement metrics that reveal intent, loyalty, and campaign health over time. These insights help you:

• Build better segments

• Improve campaign timing

• Strengthen your sender reputation

• Maximize ROI 💡

So if you’re ready to take your email strategy from good to exceptional, here are the next-level metrics you should start tracking now.

Why Go Beyond Basic Metrics?

Open rates are increasingly unreliable (thanks, Apple Mail privacy 🕵️). Clicks are helpful, but they don’t tell the full story.

📌 Advanced metrics provide context — revealing how engaged, loyal, and valuable your subscribers really are.

They help you:

• Understand the customer journey

• Build smart automation triggers

• Personalize at scale

• Reduce unsubscribes and spam complaints

Advanced Email Engagement Metrics That Matter

---

⏳ 1. Time Spent Reading (Read Rate)

What it tells you: How long users actually spend reading your email.

✅ More time = deeper interest 📉 Less than 5 seconds = skim or delete

💡 Use it to optimize email length and structure — and adjust CTA timing.

---

📥 2. Scroll Depth

What it tells you: How far down the email your subscriber scrolled.

✅ Reveals if your layout and content keep readers engaged 💡 Helps you place CTAs in the right spot — not too early or too late.

---

🔁 3. Click-to-Open Rate (CTOR)

Formula: (Clicks / Opens) x 100

What it tells you: How effective your email is after it's opened.

📌 A high open rate + low CTOR = great subject line, weak content ✅ A high CTOR = strong email body and CTA

💡 SenderWiz provides clear CTOR insights in your campaign dashboard.

---

🧑‍💻 4. Device & Client Breakdown

What it tells you: Where and how users read your emails (mobile, desktop, Gmail, Outlook, etc.)

✅ Helps you design responsive emails ✅ Reveals client-specific rendering issues

💡 Optimize for your top 2–3 platforms for best results.

---

🔄 5. Engagement Over Time

What it tells you: How your subscribers interact with your emails week over week.

Use it to:

• Identify your most loyal users

• Trigger win-back automations

• Suppress long-term inactives

💡 SenderWiz allows real-time segmentation based on this metric for smarter targeting.

---

📬 6. Email Sharing/Forwarding Rate

What it tells you: If users find your content valuable enough to pass along.

📌 Sharing = trust + viral potential Use this to measure how well you’re sparking conversations or word-of-mouth.

---

🧮 7. Conversion Rate (Post-Click)

What it tells you: Whether the email click led to a desired action (purchase, signup, etc.)

💡 Use UTM parameters and integrations to track from click to completion.

---

🔁 8. Resend Engagement

What it tells you: Do people engage when you resend to non-openers with a new subject line?

📈 A high resend CTR means your second attempt was more compelling 📉 Low results? Time to rethink your follow-up strategy.

---

📉 9. List Churn Rate

What it tells you: How many people are unsubscribing, bouncing, or going inactive.

Formula: (Unsubscribes + Hard Bounces + Complaints) / Total Sent

💡 This helps you measure list health and avoid deliverability issues.

---

📊 10. Subscriber Lifetime Engagement Value

What it tells you: How engaged a subscriber has been over time.

📌 Use this to:

• Identify VIPs

• Predict churn

• Prioritize re-engagement or sales outreach
