Use IM and SMS messages
8x8 Work enables you to send and receive messages via desktop or mobile with your colleagues or with external contacts. Do you want to make your messages more effective by attaching a file you are discussing, emphasize key parts of a message, or even take a particularly important conversation to the next level via 8x8 Meet? 8x8 Work messaging allows all of this, and more!
The advanced noise management capability of the app automatically detects which computer or device the user is accessing more actively to send and view messages, and suppresses notifications on the less-active device.
Note: IM is available for all 8x8 customers, while SMS messaging is currently available only for phone numbers in the United States and Canada.
For details on messaging a group of people, please refer to how you can use:
Important: Depending on your organization's requirements for 8x8 Work for Desktop, you may have access to Team Messaging or to group chat.

When you send an IM message to a company contact, it allows you to see the contact’s availability status, and whether the message has been successfully sent and read.
If you send the wrong information in a message or send a message to the wrong chat, you can edit or delete the message as needed.
To write a new message to a company contact:
- Open Messages
to view your list of chats.
- Click the New
option to bring up a menu.
- In the menu that pops up, select Message to open the contact directory.
- Search and click the desired company contact to chat with, and begin writing the message. If the contact has multiple phone numbers you can message, clicking the contact reveals the list of phone numbers; from the list, click the desired number. For the best messaging experience, select the contact's 8x8 Work number (listed with their four-digit user extension).
To reply in a conversation with a company contact:

You can send an SMS by writing a new message from scratch, or looking through your list of existing chats. Sending a message to an external number or a personal contact results in an SMS, which shows you whether the message has been successfully sent, but does not allow you to track the contact’s availability status or whether the message has been read.
Note that SMS messaging must be enabled for your phone system for you to use SMS on 8x8 Work.
