Nylas

Nylas is an API platform for email, calendar, and contact sync. Developers integrate Nylas to unify data from Gmail, Outlook, Exchange, and IMAP mailboxes in one connection. A single REST API handles read/send email, contact management, and scheduling. Built-in webhooks push real-time updates to applications. Nylas also includes natural language parsing for events or contact details. While not a typical email client or server, Nylas suits SaaS companies wanting to embed multi-provider email capabilities without building separate integrations for each service.
