The special feature of Mac MBOX to HTML Converter is that the HTML code remains intact after the conversion and all the images in the attachments of the respective emails are in proper order like in the case with migration of emails from MBOX file to Outlook
Great tool! Converted my MBOX emails to HTML format accurately. No need to worry of the HTML formatting and syntax while uploading the code to any website or sending email. Thanks to the creative team for free MBOX to HTMl Converter.- Carlous Tandon, Mexico
