SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill removes the friction of configuring a user’s own Resend credentials so an assistant can reliably send emails from the user’s verified domain without exposing secrets in chat.

Core Features & Use Cases

  • API-key credential storage (secure, out of chat): Collects a user-provided Resend API key via the credential vault and sets up the correct Authorization header injection.
  • Verified-domain detection and sender defaults: Detects a verified Resend domain automatically from the user’s Resend domains list and prepares a default sender address.
  • Connection verification and optional inbound webhook setup: Confirms the API key works via domain API calls and can register an email-received webhook while storing the webhook signing secret.
  • Safe-by-design sending flow: Enforces that from must belong to a verified domain and instructs confirmation before sending any email.

Quick Start

Ask the assistant to set up Resend using your account so it can store your API key, detect your verified domain, verify the connection, and enable outbound email sending.

Frequently Asked Questions about resend-setup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Resend to send emails from a verified domain?▼

To set up Resend for verified-domain email sending, you provide your API key via a secure credential vault, which automatically detects your verified Resend domains and prepares a default sender address for outbound messages.

How do I securely store a Resend API key for automated email sending?▼

Secure Resend API key storage is handled through a credential vault that injects the correct Authorization header for proxied REST calls, ensuring your secret is never exposed in chat.

Can I receive inbound emails via a Resend webhook?▼

Yes, you can receive inbound emails by registering an email-received webhook during setup, which automatically stores the webhook signing secret in the credential vault for secure inbound processing.

How does verified-domain detection work for Resend email sending?▼

Verified-domain detection automatically queries your Resend domains list to identify valid domains and enforces that the `from` address belongs to one, ensuring safe-by-design outbound email sending.

Do I need to manually verify my Resend API key connection?▼

No, the setup process automatically verifies the API key connection by making domain API calls to confirm the credentials work before enabling outbound email sending.

What are the limitations of using Resend for automated email sending?▼

A key limitation is that the `from` address must strictly belong to a verified Resend domain, and the system requires user confirmation before sending any email to prevent unauthorized outbound messages.
