Understanding Email Bounce Rate
What is Email Bounce Rate?
Email Bounce Rate is the percentage of emails in a campaign that were not successfully delivered to the recipients’ inboxes. A “bounce” means the email was rejected by the recipient’s mail server. Monitoring this metric is crucial for assessing the quality of your email list and the health of your sender reputation.
How to Calculate Bounce Rate
The formula for calculating email bounce rate is simple:
Our calculator automates this for you, giving you an immediate percentage to evaluate your campaign’s deliverability.
Soft Bounce vs. Hard Bounce
It’s important to distinguish between the two types of bounces:
- Soft Bounces are temporary delivery failures. This could be due to a full inbox, a server that is temporarily down, or an email message that is too large. These emails may be deliverable at a later time.
- Hard Bounces are permanent delivery failures. This happens when an email address is invalid, fake, or no longer exists. Email addresses that result in a hard bounce should be removed from your list immediately.
Why is a Low Bounce Rate Important?
Internet Service Providers (ISPs) like Gmail and Outlook use bounce rates to determine a sender’s reputation. A consistently high bounce rate signals that you may be sending unsolicited emails or have a poorly maintained list. This can lead to:
- Poor Deliverability: Your future emails are more likely to be sent directly to the spam folder.
- Damaged Sender Reputation: It becomes harder for all your emails to reach the inbox, impacting your entire email marketing program.
- Wasted Resources: You’re spending time and money trying to reach contacts that don’t exist.
As a general rule, a bounce rate under 2% is considered good, while anything over 5% requires immediate attention.
