Delivery rate measures the percentage of emails successfully delivered to recipients' mailboxes. It's calculated as: shopify
Delivery rate = (Number of emails delivered ÷ Total number of sent emails) × 100
A healthy delivery rate is 95% or above. If your delivery rate drops below this threshold, it indicates issues with your email list quality, possibly containing fake or expired addresses.
How to improve:
- Regularly clean your email list
- Use double opt-in processes
- Remove bounced emails promptly
- Monitor sender reputation

5. Conversion Rate

- Soft bounces: Temporary issues (full inbox, server problems)
Target: Keep bounce rates below 2% for optimal deliverability.
7. Unsubscribe Rate
This metric tracks the percentage of recipients who opt out of your email list. While some unsubscribes are normal, high rates may indicate content or frequency issues.
