What is a Bounced Email
A bounced email is rejected by an email server and it won’t reach the recipient’s inbox. Hard bounce rate is an essential metric to your account reputation because it reduces campaign effectiveness. It causes future emails to land in spam folders because spam filters flag high hard-bounced rates as potential spamming, and a high bounce rate may cause email providers to block your email domain entirely and add your IP address to blacklists.
The benchmark for bounce rate is 2%. Your account will be considered unhealthy when it exceeds 2%. It will be considered risky if your bounce rate is over 5% or even higher.
Hard Bounce & Soft Bounce
- A Hard Bounce indicates an email that couldn’t be delivered due to a permanent error, such as the email being sent to an invalid address, the email provider having a strict email security filter, etc. Notice: To protect your email reputation, when a contact hard-bounced on a campaign email, MailExpress automatically excludes this contact from the future email contact list.
- A Soft Bounce indicates an email couldn’t be delivered because of a temporary problem with the recipient's email server, such as the recipient’s mailbox being full, the email being too large, the server undergoing some configuration changes, etc. Notice: Contacts who are soft-bounced are eligible to receive future emails from you.
Commons Reasons for Bounces:
- Hard bounces: This mailbox is disabled/unavailable/does not exist.
- Soft bounces: Blocked due to spam content, the email account is over quota.
