Developers who would rather not build separate Gmail and Outlook integrations get one API, with a free plan and usage fees beyond limits.

Kenning's take

What it does

Nylas gives developers one API for email, contacts and calendars across Gmail, Microsoft, Exchange and IMAP providers. It also offers a Notetaker API that joins meetings to transcribe them, and Agent Accounts, which give an AI agent its own inbox and calendar. Every plan includes all of these products.

• Email and contacts API with two-way sync
• Calendar API and embeddable scheduler
• Notetaker API for meeting transcripts
• Agent Accounts with their own inbox and calendar
• SDKs for Node, Python, Ruby and Kotlin

Who it suits. Software teams building email, scheduling or AI agent features into their own products.
