What does the software or service do well? Docsend is by far the most convenient and effective tool that I ever used for a client presentation! What I liked most is you can store your documents safely mostly if you want to share it externally. Docsend helps professionals in securing the file and create a link or even multiple links for a single file if you want to track different people or groups of people. Each time someone clicks on this link, it opens the document in DocSend’s HTML viewer in your browser — and of course, you'd be able to track them in the most convenient way! You will know if the recipient went through all the slides or pages, and you even know how much time he or she spent on every slide. You know if he or she forwarded the document to someone else as DocSend collects email addresses of people who opened the document. You could also set an expiration date wherein it could limit the days and time to make the file viewable.
What does the software or service not do well? There are minimal bugs that I have encountered using Docsend but their customer support is indeed helpful in resolving it. Sometimes the web crashes mostly if you have a weak internet connection and takes a hard time to upload files.
What do you wish you had known about the software or service before using? I wish there is a mobile app for this tool so I could access it even I'm out of the office. I'm also hoping that we can upload files in Docsend using other file formats such as Powerpoint or MS Word. Currently, we can use Docsend by uploading PDF files only.
