Resend — Email Skill
When to use
Use this skill when a squad needs to send emails — welcome messages, notifications,
reports, newsletters, or any transactional/marketing email. Resend handles delivery
so the squad only needs to compose the content and call the MCP tools.
Instructions
Sending a single email
- Prepare from, to, subject, and body (HTML or plain text).
- Call the Resend MCP
send_email tool.
- Check the response for a successful
id — that confirms the email was queued.
Sending a batch
- Build an array of email objects (same fields as single send).
- Call the Resend MCP
batch_send_emails tool.
- Each item in the response will have its own
id or error.
Attachments
Pass attachments as an array with filename, path (local file), url, or content (base64).
Scheduling
Include a scheduled_at field (ISO 8601 datetime) to schedule future delivery.
Best practices
- Validate from against a verified domain before sending — Resend rejects unverified senders.
- Keep subject lines under 80 characters for better deliverability.
- For batch sends, group by shared content to reduce payload size.
- Always check the response for errors and surface them to the user rather than silently failing.
- When composing HTML emails, keep the markup simple — most email clients ignore complex CSS.
Available operations
