Hi, I was in a difficult situation a few months ago when I needed to transfer hundreds of .eml files from an old backup into my new IMAP-based email account. After trying a few manual options that were confusing and time-consuming, I found a much easier solution using Advik EML Converter. Here's what worked for me: I installed the Advik EML Converter on my Windows PC. Added the folder containing all my .eml files. From the saving options, I selected IMAP. Then I entered my webmail login details (email, password, and IMAP server – usually something like imap.example.com). Hit the Convert button. In just a few minutes, all my .eml emails were uploaded to my webmail account, and I could access them from anywhere like regular emails. What I liked: No need for Outlook, Thunderbird, or any email client. It kept all the original dates, sender info, and attachments. The interface was very beginner-friendly. If you’re looking for a straightforward, error-free way to upload your EML files, I highly recommend giving this tool a try. There's even a free demo to test it out before buying.
