Our live chat has a lot of returning visitors for tech support issues, and our agents have noticed that a returning visitor’s chat history is only retained if the visitor is using the same browser (based on browser cookies). We are looking for a way to identify returning visitors based on the email address they enter in the pre-chat form, so that when they reach out to us again on a separate device, their previous chat history is retained. I believe this is possible to develop on the back-end, but have no development experience, so am looking for some direction on who could potentially get this done.
Any assistance is greatly appreciated!
Thanks
