<h2 id="what-is-email-bounce-back">What is Email Bounce Back?

Email bounce back, also known as email bounce or email failure, occurs when an email cannot be delivered to the intended recipient's inbox and is returned to the sender. Bounce backs can be caused by various factors, including invalid email addresses, full mailboxes, or server issues. It is essential to identify and address bounce backs promptly to maintain a healthy email deliverability rate.

<h2 id="types-of-email-bounce-backs">Types of Email Bounce Backs

There are two main types of email bounce backs:

  1. Hard Bounce: A hard bounce occurs when an email fails to reach the recipient due to permanent reasons, such as an invalid or non-existent email address. Hard bounces indicate a permanent delivery failure and should be removed from your mailing list to maintain data accuracy and deliverability.
  2. Soft Bounce: A soft bounce occurs when an email is temporarily unable to reach the recipient's inbox. Soft bounces can be caused by reasons like a full mailbox, server issues, or a temporarily unavailable email server. Soft bounces may resolve themselves, and the email may be successfully delivered in subsequent attempts.

Email bounce backs can occur due to various reasons. Some common reasons include:

  • Invalid Email Address: If the email address is misspelled, contains typographical errors, or doesn't exist, the email will bounce back.
  • Full Mailbox: If the recipient's mailbox is full or over its storage limit, the email cannot be delivered and will bounce back.
  • Server Issues: Temporary server issues, such as a busy or unresponsive server, can cause email bounce backs.
  • Blacklisting: If your email server or IP address is blacklisted by the recipient's email provider or spam filters, your emails may bounce back.

<h2 id="how-to-check-email-bounce-backs">How to Check Email Bounce Backs

To check email bounce backs, you can follow these steps:

  1. Monitor your email delivery reports: Most email service providers offer delivery reports or bounce back reports that provide information about the emails that have bounced back. These reports typically include the bounce type (hard or soft bounce), bounce reason, and the specific email addresses that bounced.
  2. Use email verification tools: There are several email verification tools available that can help you identify email addresses that are likely to bounce. These tools can validate email addresses in real-time or in bulk, allowing you to clean up your email list and reduce the chances of bounce backs.
  3. Check bounce back codes: Bounce back codes provide information about the specific reason for the bounce. These codes are usually included in the bounce back message or delivery report. By understanding the bounce back codes, you can diagnose the issue and take appropriate action.

To reduce email bounce backs and improve your email deliverability, consider implementing the following best practices:

  • Regularly clean your email list: Regularly remove invalid and inactive email addresses from your mailing list to maintain data accuracy and reduce bounce backs.
  • Authenticate your email: Implement email authentication protocols like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify your email and improve deliverability.
  • Monitor bounce back reports: Regularly review bounce back reports provided by your email service provider and take action on hard bounces by removing the addresses from your list.
