Nylas

Nylas is an API for working with email, calendar and meeting data from many providers. It gives an application one data layer instead of a separate integration for each service.

Nylas connects to providers such as Gmail, Microsoft accounts, Exchange and IMAP servers. Applications can send, receive, thread and parse email, and read or create calendar events with two-way sync. The platform also includes embeddable scheduling components and agent accounts, which give an AI agent its own inbox and calendar.

• Send, receive and thread email across providers
• Two-way calendar sync with Google, Microsoft and iCloud
• Embeddable scheduler and booking components
• Virtual calendars for rooms and equipment
• Agent accounts with an inbox and a calendar

Software companies that want email or calendar features inside their product without building each provider integration. Teams building AI agents that need to read and send email or manage meetings also use it.

The company offers a free way to start building, and pricing pages list the plans for larger use. Because the data comes from third-party providers, each provider's access rules and limits also apply to your app.
