# Contacts

[Open in personal cabinet](https://my.tuna.am/team_contacts)

Contacts are groups of notification recipients. Each group can contain email addresses and [integrations](https://tuna.am/en/docs/team/integrations.md) (Telegram, Slack, etc.).

## Concept

The notification system is built on three levels:

```shell
┌────────────────────────┐     ┌──────────────────┐     ┌──────────────────────┐
│   Monitor or report    │────▶│  Contact group   │────▶│    Contact           │
│                        │     │   "DevOps"       │     │ (email/integration)  │
└────────────────────────┘     └──────────────────┘     └──────────────────────┘

```

1. **Monitor or report** — event source
2. **Contact group** — a set of recipients for a specific purpose
3. **Contact** — a specific recipient (email or integration)

This structure allows you to:

* Flexibly manage notification recipients
* Use the same group for multiple monitors
* Easily add/remove recipients
