If you're trying to import emails into your Thunderbird account, I highly recommend the Thunderbird Import Tool. It’s hands-down one of the easiest and most reliable tools I’ve come across. Whether you’re dealing with EML, MBOX, or other formats, this tool handles everything smoothly, even with bulk files.
It auto-detects Thunderbird profiles, maintains folder structure, and keeps attachments intact. Unlike some add-ons, it doesn’t crash with large data. I randomly suggest it to anyone looking for a hassle-free import solution for Thunderbird, especially if you want speed, accuracy, and zero file corruption. It just works.
