Twenty connects to your existing tools so your CRM stays up to date without manual data entry.

## Email sync

Connect your **Google Workspace** or **Microsoft 365** mailbox. Once connected:

- Emails are automatically linked to the matching Company and People records
- Full email threads are visible on each record's timeline
- You can send emails directly from Twenty
- Multiple mailboxes per user are supported

You control what gets imported — filter by date range or sender to avoid pulling in irrelevant emails.

## Calendar sync

Calendar events sync automatically from your connected account. Events appear on the relevant CRM records, giving you a complete picture of your interactions with each contact or company.

## Integrations

Beyond email and calendar, Twenty connects to external tools through:

| Method | Use case |
|--------|----------|
| **API** | Build custom integrations with the GraphQL or REST API |
| **Webhooks** | Push real-time notifications to external systems when records change |
| **Zapier** | Connect to 5,000+ apps without code |
| **Workflow HTTP actions** | Call any external API as part of an automated workflow |

## Custom apps

Developers can build full-featured apps on top of Twenty — adding custom UI, server-side logic, and deep integrations. Apps can be published for the community or kept private.
