Bounce rate has two meanings. In email, it's the percentage of emails that couldn't be delivered. In web analytics, it's the percentage of visitors who leave after viewing only one page. Both are early-warning signals — high email bounce hurts deliverability; high web bounce signals poor relevance or UX.
What is Bounce Rate?
Bounce rate has two important meanings, depending on whether we’re talking about email marketing or website analytics:
Email Bounce Rate
The percentage of emails that couldn’t be delivered to their intended recipients.
Email Bounce Rate = (Bounced Emails ÷ Sent Emails) × 100Undelivered email
Website Bounce Rate
The percentage of visitors who leave your website after viewing only one page.
Website Bounce Rate = (Single-page Sessions ÷ Total Sessions) × 100One-and-done visits
👆 Fun Fact: The term “bounce” comes from the early days of email when undeliverable messages would literally “bounce back” to the sender. Now that’s a visual metaphor that stuck! 📧↩️
Types of Bounces

- Hard Bounces: Permanent delivery failures due to invalid email addresses, closed accounts, or non-existent domains.
- Soft Bounces: Temporary delivery issues like full mailboxes, server problems, or size limitations.
Website Bounces
