Calendar & Email - Twenty

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.
