RJ Leather Sewing School review for Chatra — Live Chat & Chatbot

I have used this ap for a while now and find it is brilliant. The only slight frustrating thing is that some client do not always leave their email address so its means they send an enquiry but I cannot respond to them. That is the clients fault not chatra, however I wonder if there is a way the ap would have first option to add their email address, then write a message?
