Sync Any Email Account Into Your Application

Email is the backbone of all business communications, making it a mission-critical feature for many software applications. And yet, any developer who has built an email integration knows it’s no easy feat. Integrating with just one email provider, let alone multiple providers, requires a huge upfront lift and ongoing maintenance work as the email providers update their APIs.

That’s why we built the Nylas Email API, so developers can build email connectivity into their application with ease. The Nylas API makes it easy to integrate Gmail, Outlook, Microsoft Exchange, Office 365 and the rest into your application.

Integrate Email in 4 Lines of Code

The Nylas Email API provides a seamless email integration across any provider. Power your application with full CRUD and bi-directional sync from any inbox in the world.

    
import Nylas from 'nylas';   Nylas.config({ appId: APP_ID, appSecret: APP_SECRET, });   var nylas = \Nylas.with(ACCESS_TOKEN);   nylas.threads .count({in:'inbox'}) .then(count => { console.log( `There are ${count} events in your inbox.` ); });
    
from nylas import APIClient   client = APIClient( APP_ID, APP_SECRET, ACCESS_TOKEN, )
threads = \client.threads.where( unread=True, limit=5, )  for thread in threads: print(thread.subject)
    
require 'nylas'   nylas = Nylas::API.new( app_id: APP_ID, app_secret: APP_SECRET, access_token: ACCESS_TOKEN )   threads = nylas .threads.search("Hello!")   threads.each do |thread| puts thread subject end

“Nylas allowed us to integrate with Office365, Outlook, Exchange, and IMAP email providers in a scalable way.

The new features we built with the Nylas API help users understand each contact, opportunity, or deal at a glance — and because they don't have to switch to another app to communicate, they can be much more productive and close deals faster.

Nylas made it easy for us to deliver great email features that are also secure, reliable, and scalable.”
