A bounce means an email has not been delivered to your subscribers' inboxes. A bounce can be classified as a soft or hard bounce.
- Soft bounces occur when emails are dispatched, but the recipient’s mailbox is temporarily down, or the email server is full to receive your email.
- Hard bounces are emails that are permanently undelivered. Typos in the email address or invalid domain names cause hard bounces.
Note: Vtiger CRM removes the email address from the marketing list when a hard bounce occurs on an email.
