Started out as a paying customer - love this software, and their support team is A++ - incredibly responsive. If you work in sales, marketing or consulting, and send out proposals or presentations or other marketing collateral, the insights docsify generates are priceless. A quick overview of what it does that's so helpful -- basically, it can convert your proposals and marketing materials into web-viewable documents (so recipient doesn’t have to download and can read on mobile) and gives you page by page analytics to show you what a prospect opened, where they scrolled, what they read, what they seemed to get excited about, etc ... and then tell you if they clicked through to any specific links you sent them, which ones, where they went, etc. - all stuff that's really valuable as part of a sales funnel. Then you can custom target follow up calls and sales materials based on real time data, and zero in on what will help you to focus in on to close a sale. For ongoing client relationships once you've made a sale, helps you know when clients actually read and engage with work you sent them so it’s not just a black box after you attach a document and click send - you know if they opened the email, viewed the document, spent real time on it, etc. And if you sent materials to several people / clients on an email, will give you custom analytics around download / open / scroll on a per person basis. With data that’s searchable by document, by person across documents (so you know if someone consistently doesn’t engage with your materials but others do), etc. It’s really powerful stuff once you get into the thick of it. Excited to see this on here.
