How to use the email bounce rate calculator

To calculate the email bounce rate, enter the total number of bounced emails and the total number of emails that you sent during a campaign. The tool will instantly calculate your bounce rate, helping you understand the health of your email list.

Email bounce rate formula

Email Bounce Rate (%) = (Number of Bounced Emails/Number of Emails Sent​) × 100

Understanding the email bounce rate result

The ideal email bounce rate is generally considered to be under 2%.

• A low email bounce rate indicates a clean email list with valid, active recipients and suggests that you have good sender reputation and deliverability.
• A high email bounce rate signals potential issues with your email list, such as outdated or incorrect addresses, which can harm your sender reputation and limit email deliverability.

When to calculate email bounce rate

Email bounce rate should be calculated regularly to monitor deliverability and maintain a healthy email list. Some of the important scenarios where you should calculate your email bounce rate include:

• After sending a new email marketing campaign
• During routine list hygiene checks to identify and remove invalid or inactive addresses
• To evaluate the impact of list growth strategies on bounce rates
• While assessing the quality of newly acquired email lists or subscribers
• To benchmark against industry standards or competitors' bounce rates

How to calculate Email bounce rate with example

Imagine that you sent 10,000 emails in a campaign, and 200 of them bounced. You can calculate your email bounce rate as follows:

Email Bounce Rate (%) = (Number of Bounced Emails/Number of Emails Sent​) × 100

Email Bounce Rate = (200/10,000) × 100 = 2%

In this example, your email bounce rate is 2%, which means that 2% of the emails sent could not be delivered to the recipients’ inboxes.

How to improve your email bounce rate

You can improve your email bounce rate by using the following strategies:

• Regularly clean your email list by removing invalid or inactive addresses.
• Use double opt-in methods to verify new subscribers.
• Authenticate your emails with SPF, DKIM, and DMARC protocols.
• Segment your list to send more targeted and relevant content.
• Avoid using spam trigger words in your subject lines and content.
• Ensure your email server's IP address has a good sender reputation.
• Use a reputable email service provider to enhance deliverability.

##What are the types of bounce emails?
