What is Email Bounce Rate?

Email bounce rate refers to the percentage of emails sent that were undeliverable and returned to the sender. This can occur due to a variety of reasons such as invalid email addresses, full inboxes, or blocked domains. There are two types of email bounce rates.

A soft bounce is an email delivery failure that is temporary and can be resolved. Some common causes of soft bounces include a full inbox, a temporarily down email server, or a recipient’s email address temporarily unavailable.

A hard bounce, on the other hand, is a permanent delivery failure, often due to a permanent error such as a non-existent email address or a domain that has blocked the sender’s email. Hard bounces are more serious than soft bounces as they indicate that an email address is no longer active or valid and should be removed from the mailing list to maintain a good sender reputation.

It’s important to track both soft and hard bounces to understand the underlying reasons for email delivery failures and make necessary adjustments to improve email deliverability.

A high email bounce rate can indicate a problem with the recipient list and may require cleaning or updating to improve deliverability. Measuring email bounce rate is important for businesses and individuals who send out mass emails. A high bounce rate can flag their account as a spammer, leading to reduced deliverability in the future.

What is Average Email Bounce Rates?

The average email bounce rate varies depending on several factors, such as the size of the email list, the quality of the email addresses, the type of emails being sent, and the sender’s reputation. Generally, a bounce rate of 2-3% is considered normal for a well-maintained email list.

However, it’s important to note that some industries and types of emails may have higher bounce rates, such as B2B emails which often have a higher bounce rate due to outdated email addresses and full inboxes. On the other hand, B2C emails, such as newsletters and promotional emails, typically have a lower bounce rate.

It’s important to monitor your own bounce rate and compare it against industry benchmarks to determine if your bounce rate is within a healthy range and make adjustments as necessary to improve email deliverability. To maintain a healthy bounce rate, it’s crucial to regularly clean and validate email lists.
