By including your contact information in every e-mail you send, you make it easy for the recipient to respond to you, whether by e-mail, telephone, or post. Most e-mail programs have this feature. They also have the capability for you to program various auto signatures for you to use with different audiences. A standard, default auto signature might look like this:
Clint
Clint Smith, Vice President
ABC Company
123 Park Road
Anywhere, PA, 19500
610-xxx-xxxx
TF: 877-xxx-xxxx
F: 610-xxx-xxxx
C: 610-xxx-xxxx
