Frequently asked questions

What is contextual email?

Contextual email means that your email lives within the context of a larger application, with direct access to data from users’ personal email accounts. Unlike transactional email APIs, contextual email APIs are designed for developers that need to embed robust send and receive email capabilities, core email management tools, and analytics—all while achieving near-perfect email deliverability. Contextual APIs allow your users’ to preserve their email accounts rather than using a third-party (transactional) inbox.

How do I build an email client in my application?

To embed an email client in your application, you’ll need to build integrations with email service providers. By connecting with these providers, you can read, send, and delete emails directly from a user’s inbox. You’ll also want to provide support for essential inbox management tools such as threads, folders, and labels to make it easier to sort and reply to conversations.

How do I integrate other email providers into my app with Nylas APIs?

The Nylas Email API supports 100% of email service providers through a single integration, including Gmail, Microsoft Outlook, Microsoft Exchange, Microsoft 365 Email, and IMAP.
