Sizle is a great tool to share files we don't want copied or modified.
The best part about Sizle is seeing who viewed a presentation, which slides they focused on and for how long before following up.
Understanding when, where and how much recipients engage with our decks helps tremendously with follow-up.
The sales team were amazed they could see what slides clients were reviewing in real time.
Being able to quickly and securely share a doc with full analytics has streamlined my full workflow.
The insights are detailed and actionable. No more wondering if a client has opened an email.
