Bounce rates are critical indicators of email deliverability issues. There are two types of bounces:
Soft Bounces: Temporary delivery failures due to issues like a full mailbox or server downtime. These emails can be retried later. Hard Bounces: Permanent delivery failures caused by invalid email addresses or non-existent domains. These addresses should be removed from your list immediately.
Implementing bounce management protocols and regularly cleaning your email list can help maintain a healthy sender reputation.
