A sale announcement and a project discussion need different recipient arrangements. The choice determines who can see replies. It also changes which recipients and messages your team counts.

## Campaigns give each recipient a private conversation

Choose a campaign when each person should receive their own relevant offer or update. Include only customers who agreed to receive the campaign. Give each recipient a way to reply privately. Other recipients are not added to the same room.

## Groups coordinate a shared task

Use a group for people who need to coordinate a shared task. Explain the purpose, invite the intended participants and keep a business owner responsible for the conversation.

## Group messages and participant updates use different counts

Count sent group messages separately from participant-specific delivery or read updates. Use the recipient field, when provided, to identify the participant. A campaign audience, a group’s participants and the count of messages are different reporting units.
