Why use Vercel Connect with SMTPing?

  • Credentials on demand

    Request SMTPing credentials only when your application or agent needs them instead of copying secrets into application code.

  • Access for the right subject

    Request user-authorized SMTPing access so actions follow the identity and permissions of the person using your application.

  • Centralized credential management

    Manage SMTPing credentials in one place and retrieve them through a consistent runtime API.

  • Vercel-native controls

    Bind connections to the projects and environments that need them while Vercel OIDC authenticates each runtime request.

Use SMTPing with your stack

Follow a complete setup for the Connect SDK or a supported agent framework.

Add SMTPing to an existing Vercel application with the Connect SDK.

  2. Create the SMTPing connector
