Emails . SMS . OTP . Push Notifications
You communicate with your users primarily through Emails, SMS (Text Messages) and Push Notifications.
To illustrate .....
User Sign Up - Send a verification Email or One-Time-Password (OTP).
After Signup - Send a welcome email.
Forgot Password - Send a reset password link or OTP.
User Purchased Something - Send an order confirmation Email and SMS.
The list goes on. You can trigger transactional and marketing messages manually, via the API, or via rules/automations.
