Overview

Mail providers define how emails are sent inside CREDO. The system is provider-based, meaning you can swap email services without changing your authentication logic.

Each mail provider implements the same interface, ensuring a consistent API regardless of the underlying service.

Available Providers​

  • Console Provider
    Logs emails to the console (useful for development and testing).

  • Nodemailer Provider
    Sends emails using SMTP-based services like Gmail or Outlook.

  • Resend Provider
    Uses the Resend API for modern transactional email delivery.

  • Custom Mail Provider
    Allows you to plug in any email service of your choice.

Provider Responsibilities​

Every mail provider must:

  • Send verification emails
  • Send OTP or password reset emails
  • Accept standardized input data from CREDO
