I am trying to force my clients to use the Basecamp project management software. I pay for it and set them up with the project login. The problem is when I have 4 projects going on and they are not using a project management system I get 30 emails per day. I can't keep organized.
I make it very clear to my client the benefits of using Basecamp, but they all refuse and just keep sending email after email. How can I get them to send all project requests through this project management software? Should I put it in my contract? Just send a response template email saying requests must be made through basecamp until they get the hint?
