In any type of support department clear communication with clients is essential for both efficiency and to build strong lasting brand loyalty. I have found that providing screenshots and videos are a great way to both clearly articulate an answer or to clarify a request.
I tried using several methods to provide screenshots to clients and free services but after much trial and error I have found Snagit to be worth the money invested. The service works well and the time it saves comparted to other free options is well worth the cost.
