Why this KPI matters

Unsubscribes tell you when content, cadence, or audience fit is off. A steady trickle is normal as lists change over time. Spikes point to message misfires, weak targeting, or fatigue. Managing this rate protects deliverability, improves engagement, and keeps paid acquisition from carrying the full load.

How to calculate it correctly

1. Choose your lens. Many teams track an overall list rate (unsubscribes divided by total subscribers, as shown above) and a per-send rate (unsubscribes divided by delivered emails for that send). Use both for a full view.
2. Use delivered, not sent, for per-send. Exclude bounces from the denominator so the math reflects real recipients.
3. Segment by source and campaign type. Lifecycle flows, promotions, and newsletters behave differently.

Data you need

• Subscriber list with join date and source
• Campaign sends with delivered, opens, clicks, unsubscribes, and complaints
• Template and topic tags for analysis

How to reduce unsubscribes

• Set expectations early. Tell subscribers what you send and how often. Meet that promise.
• Offer frequency controls. Let people switch to weekly or monthly instead of leaving entirely.
• Clean your list. Sunset unengaged contacts after a fair win-back attempt. Better to trim than to hurt deliverability.
• Send useful content. Tie messages to customer goals and lifecycle stages, not just promotions.
• Target carefully. Segment by behaviour and past purchases. Stop sending everything to everyone.

Track unsubscribes in Klips

1. Connect your ESP. Pull sends and list events from platforms like Mailchimp, HubSpot, or SendGrid.
2. Model metrics. Calculate overall list unsubscribe rate, per-send rate, and 7-day and 30-day moving averages.
3. Visualize. Use a line chart for trend, a bar chart by template or topic, and a single-value Klip for this month.
4. Set alerts. Colour rules flag sends above your threshold. Add a table of outlier campaigns with subject lines.
5. Share. Send a weekly email to content and CRM owners so they can adjust topics and frequency.

Common pitfalls

• All-time math. Using total historical subscribers hides current problems. Use rolling windows.
• Forcing logins to unsubscribe. Create friction and you raise complaints. Keep the path easy.
• Counting spam complaints as unsubscribes. Track them separately and escalate quickly if they rise.
