All members can send DMs. Guests can participate in DMs, but they can only start their own with members who are in the same channel(s).
Free, Standard, Plus, and Enterprise Grid plans
While most discussions in Slack happen in channels, direct messages (DMs) work well for one-off conversations that don't require an entire channel to weigh in. DMs are smaller conversations outside of channels, between you and up to eight other people.

Send direct messages
Sending a DM is just like creating any other message in Slack:
Click All DMs at the top of your left sidebar. If you don't see this option, click More to find it.
Type the name of a person (up to eight) in the To: field.
If you need to add others to a conversation, you can invite them from an existing group DM. Adding someone new will start a new DM without the previous conversation’s history.

Use your personal direct message
In Slack, your personal DM is a lot like a notepad. Record notes and ideas, or use this space for whatever you might need.
