Have you ever had to look through dozens of emails for contact info for a person? We have. Its frustrating. When setting up your email signature, be sure to include all of the useful contact info including email, phone number, address and any social media accounts you might regularly use. This will improve the customer service relationships with your customers by providing them with quick access to your info. It also facilitates networking as it gives current customers a quick set of contact information to copy/paste and pass along.
