Email to PDF for Outlook gets an 8 as a rating from me because it is pretty good at almost everything it does and helps me and my business be more organized and efficient when sending and receiving documents and categorizing important information. It loses 2 marks from me for not being able to automatically save emails or remove sender and receiver information.
I have not used any other products like Email to PDF for Outlook so I am not able to say how Email to PDF for Outlook stacks up against competitors in terms of easy of use, cost, efficiency, helpfulness, etc. When I have tried other products, I would be better able to make that assessment.
