To open EML file in Gmail account, you can follow a manual process that involves a few steps. First, you need to open the EML file using an email client like Outlook or Windows Mail. Then, forward the email content to your Gmail address manually. Alternatively, you can drag and drop the EML file into a new email as an attachment and send it to your Gmail account. However, this manual method is not only time-consuming but also comes with limitations, such as the inability to open multiple EML files at once or preserve folder structure and metadata.
