I have been using pitch engine since 2016 to manage my client relationships with both digital marketers as well as non profit organizations that need help getting started in their social fundraising efforts! The platform has made it super simple to connect with potential clients from across our network of partners around the country who want assistance reaching out to prospects/clients they already know or don't yet but would like them to see what we do (and how effective it can be).
It also really helps us get organized so all outreach goes through one place instead of having many different emails sent via individual accounts which sometimes leads me to being confused about where messages were actually going vs where someone intended them too go! In addition there was no way at first to track your message performance metrics until you signed up for an upgrade - not sure why this wasn’t implemented earlier? You will definitely find something.
