Start With Your Goal
The right metrics depend on what email is for in your business. A newsletter that sends readers to articles cares about clicks. A store cares about revenue. A coach cares about booked calls.
Pick one main outcome metric that reflects your goal, then a few health metrics that warn you about problems before they grow.
The Core Metrics
| Metric | Formula | What it tells you |
|---|---|---|
| Click-through rate | Unique clicks ÷ delivered × 100 | Whether emails prompt action |
| Conversion rate | Conversions ÷ clicks × 100 | Whether your offer and landing page work |
| Revenue per email | Revenue ÷ emails sent | The value of each send |
| List growth rate | (New − unsubscribes − removals) ÷ list size × 100 | Whether your audience is growing |
| Unsubscribe rate | Unsubscribes ÷ delivered × 100 | Whether content matches expectations |
| Bounce rate | Bounces ÷ sent × 100 | List quality |
| Spam complaint rate | Complaints ÷ delivered × 100 | Whether people feel emails are unwanted |
| Open rate | Opens ÷ delivered × 100 | A rough, often inflated, signal of interest |
Outcome Metrics
Click-through rate is the most reliable everyday engagement signal, because a click requires a person to act. See email click-through rate.
Conversion rate and revenue per email connect email to business results. On AWeber Plus, sales tracking shows purchases made through AWeber's commerce tools; stores and analytics tools can attribute sales from tracked links.
Replies are a strong signal for newsletters and service businesses. They show genuine interest and help deliverability.
Health Metrics
- Unsubscribe rate: a steady, low rate is normal. Spikes after specific emails tell you something didn't land. See reduce email unsubscribes.
- Bounce rate: rising bounces point to list quality problems. See email bounce rate.
- Spam complaint rate: the most important health metric. Gmail and Yahoo expect complaints well below 0.3%. See Gmail and Yahoo sender requirements.
- List growth: if new signups don't outpace losses, revisit your list-building plan.
Why Open Rates Are Unreliable
Since 2021, Apple Mail Privacy Protection and similar features can load email images automatically, which records an "open" even if the person never reads the email. That inflates open rates for many lists.
Opens are still useful for spotting big trends or deliverability problems, but use clicks for tests, segments and decisions. See email open rate.
A Monthly Metrics Routine
- Record your outcome metric for the month, such as clicks, sales or bookings.
- Check health metrics: unsubscribes, bounces and complaints.
- Find your best and worst email of the month by clicks and look for patterns.
- Note list growth and which signup sources performed best.
- Pick one thing to test next month. See A/B testing emails.
Compare With Yourself, Not Averages
Published benchmarks vary widely by industry, list type and how each platform counts. They can be a loose reference, but your own trend over time is far more useful.
If your clicks rise month over month and complaints stay low, you're improving, whatever an industry average says.
Reports in AWeber
AWeber reports opens, clicks, unsubscribes and bounces for each email, with advanced message analytics on Lite and advanced reporting plus sales tracking on Plus. Tags applied on link clicks let you turn click data into segments for follow-ups. See AWeber Lite vs Plus.
