Defining Features

NotificationAPI includes an email service and exposes more email-related capabilities. It also includes an SMS service to send notifications to any country without Twilio. So overall, it's much faster and easier to set up.

Courier acts as a router around your delivery services like SendGrid. So you have to set up your own 3rd-parties. However, Courier has a strong notification workflow builder and supports connecting more channels.
