Bounce Rate measures the percentage of emails that could not be delivered to recipients’ inboxes.
Email Bounce Rate Formula
Bounce Rate = (Bounced Emails ÷ Emails Sent) × 100
There are two main types:
- Hard Bounces: Permanent delivery failures, such as invalid email addresses.
- Soft Bounces: Temporary issues, such as full inboxes or server problems.
Maintaining a low bounce rate is important for sender reputation and deliverability.
