What's a good Email Unsubscribe Rate?
A good Email Unsubscribe Rate for a local business is 0.30% or lower. Percentage of recipients who unsubscribed per email sent. An excellent Email Unsubscribe Rate — the top tier Karbon Agency grades client campaigns against — is 0.10% or lower, while 1.0% marks the minimum acceptable tier.
The three tiers Karbon grades against
| Tier | Value | What it means |
|---|---|---|
| Minimum | 1.0% | The floor. Below this, something is broken. |
| Recommended | 0.30% | The tier a healthy campaign should hit. |
| Excellent | 0.10% | Top-tier performance worth defending. |
Lower is better for this metric.
How it's calculated
(Unsubscribes / Delivered) * 100Why Email Unsubscribe Rate matters
