Heirloom is a powerful, open-source tool designed to archive your email in a highly portable and future-proof format. It converts emails from various client-specific formats (like Mbox, EML, and PST) into a standardized, human-readable set of plain text files organized by folder. This ensures your correspondence remains accessible and searchable for decades, regardless of future software obsolescence. It's built by and for individuals who value long-term data preservation.

Why It’s Useful

Unlike proprietary email archiving solutions or basic 'save as' functions, Heirloom prioritizes accessibility and longevity. Its reliance on plain text and a predictable file structure means you'll never be locked into a specific email client or platform. The tool is particularly valuable for researchers, writers, or anyone who needs to maintain an extensive and easily searchable archive of personal or professional communications. It's also excellent for migrating large volumes of email data between different services without loss or corruption, providing a robust backup strategy that traditional methods often lack.

In everyday life

When you’d actually reach for this

You can use Heirloom to back up your decade-old Gmail account before switching to a new provider. Imagine accessing an important email thread from 2015 on any computer with a text editor, without needing any special software.
