# Can I run more than one newsletter from one install?

> Channels in Broadcast keep subscribers, broadcasts, sequences, domains, and email servers isolated, so one install can run multiple newsletters or client audiences.

Yes. That is what **channels** are for. A channel is an isolated workspace: its own
subscribers, broadcasts, sequences, segments, templates, and settings.

## What isolation means

Subscribers belong to a channel. Someone on your product newsletter is not on your
company announcements list unless you put them there. Unsubscribes, suppressions,
and analytics are scoped the same way.

Channels can also carry their own **sending domain** and their own **email servers**,
so two brands sending from one install do not share a From address or a sending
reputation. [The channels documentation](https://sendbroadcast.net/docs/channels) covers
creating one, switching between them, per-channel language, and deactivation.

Each channel keeps its own subscribers, broadcasts and unsubscribes.

## Common shapes

- **Multiple brands or products** under one company
- **Agencies** running separate client audiences
- **Separating marketing from transactional** traffic so rate limits do not collide
- **Staging versus production** audiences

Switching channel changes everything beneath it: audience, campaigns, segments and settings.

## What is shared

The install itself: your license, the server, upgrades, and backups. Global
[suppressions](https://sendbroadcast.net/docs/suppression-lists) apply across every channel,
which is usually what you want for hard bounces and complaints, alongside
per-channel suppressions for narrower cases.

## Worth knowing before you commit

Channels isolate data, they do not isolate logins by client. If you need clients to
sign in and see only their own channel, that is a different requirement. Check the
[roadmap](/roadmap) and tell us if it is blocking you.

Agencies specifically may want to read the
