π What Is a Bounce Rate (and Why It Matters)?
Bounce rate in email marketing = % of emails that never reach the recipient's inbox.
There are two main types:
- β’ Hard bounce: Permanent issue (fake address, domain doesn't exist)
- β’ Soft bounce: Temporary issue (mailbox full, server error)
High bounce rate = π¨ poor deliverability, lower sender reputation, and eventually: all your emails land in spam.
