For smooth and reliable conversion of EML emails to MBOX format, EmailSoftwares EML to MBOX Converter has been designed to complete the task quickly and quite accurately. This software allows exporting multiple EML files in one go while preserving attachments, metadata, and folder structure. It is compatible with Thunderbird, Apple Mail, Eudora, and other MBOX-based email clients and doesn't depend on having the email client installed. You can check your emails using the preview before choosing to convert the files, and there's no limit on file size. Just add your EML files, select MBOX as the Output Format, choose the destination folder, and Convert. Please note that the free trial version allows you to scan and preview your EML files before you export.
