eMail Bounce Handler is a powerful bounce email filtering and handling tool for macOS and Windows. It helps you process returned emails, identify undeliverable addresses, and keep your mailing lists clean by removing bad contacts before they harm your sender reputation.

When an email cannot be delivered, the recipient’s mail server usually sends a bounce message back to the sender. These messages can be caused by invalid addresses, full mailboxes, temporary delivery problems, domain errors, server rejections, or other delivery failures. Manually reading those messages and finding the original recipient address can be slow, repetitive, and error-prone.

eMail Bounce Handler automates that work. It analyzes bounce messages, recognizes delivery failure reports using a customizable set of rules, and extracts the affected recipient addresses. Once processed, you get a clean list of bounced or “dead” email addresses that can be exported and used to clean your original mailing list or decide whether to retry delivery later.

The software can process bounce messages from many different sources, including local files, text drops, the clipboard, local mailboxes, and remote mailboxes. It supports POP, APOP, and IMAP accounts, allowing you to retrieve bounce messages directly from your mail server while leaving unrelated messages untouched.

eMail Bounce Handler includes support for SSL and TLS connections, Delivery Status Notifications, and Enhanced Mail System Status Codes. This makes it suitable for modern email systems and helps the application understand detailed delivery reports returned by mail servers.

The application comes with 60 predefined rules designed to handle almost all common bounce formats. These rules can be customized, allowing advanced users to adapt the filtering process to specific servers, message formats, languages, or delivery reports. You can also configure multiple accounts, schedule connections, define deletion marks, and review a complete connection log.

For list management, eMail Bounce Handler includes a customizable export function, so you can save the extracted bounce addresses in the format that best fits your workflow. This makes it easy to update mailing lists, remove invalid contacts, reduce repeated delivery errors, and improve the overall quality of your email campaigns.

The latest version adds TLS 1.3 support and can process several IMAP mailboxes at once, making it more secure and more efficient for users who manage multiple accounts or large volumes of returned mail.

Whether you send newsletters, customer updates, nonprofit bulletins, membership emails, or business campaigns, eMail Bounce Handler gives you a practical way to turn bounce messages into useful list-cleaning data. Instead of ignoring returned emails or sorting them manually, you can automatically extract the failed addresses, clean your lists, and send future campaigns with greater confidence.
