As with emailing a contact, texting a contact is also super-easy. All you have to do is follow the prompts through the Contact List or from within the Contact Details.
To Text a Contact:
Click on the Contact List.
Under the Contacts section, click on any contact types for that list to appear on the right.
Click on the Text icon.
Compose your message.
Click Send Text when done.
As an alternative, you can go through the Contact Details of any given contact.
Find the name of contact you wish to text, either by finding it from the list or by searching in the upper right search box.
Click on the Text icon on your right.
Compose your text and send to the contact when done.
For every communication - email, text, or call - you can find the history of your communications in the Communications History of the contact, or in the Communications Center from your Primary Navigation.
