What do we do to obtain our client's latest contact information? We simply ask them to send us the latest details after a certain period; usually, we e-mail them to get this information. It's a tedious task to write an individual e-mail to every client/contact. Salesforce provides a better way to ask your clients to stay in touch with you. You can simply use a single e-mail format, and with a click of a button, you can directly send an e-mail to your contact and get the latest information. This functionality of Salesforce is known as Stay-in-Touch.
