Resend Email

Resend Email

Send emails from any Resend-verified domain using the Resend API.

Quick Start

# Send simple email
bash skills/resend-email/scripts/send.sh \
  --to "recipient@example.com" \
  --subject "Subject Line" \
  --body "Email body text"

# With custom from address
bash skills/resend-email/scripts/send.sh \
  --to "recipient@example.com" \
  --from "you@yourdomain.com" \
  --subject "Subject" \
  --body "Body"

Direct API Call

curl -X POST 'https://api.resend.com/emails' \
  -H "Authorization: Bearer $(cat ~/.config/resend/credentials.json | jq -r .api_key)" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "noreply@yourdomain.com",
    "to": ["recipient@example.com"],
    "subject": "Subject",
    "text": "Plain text body"
  }'

Configuration

• Credentials: ~/.config/resend/credentials.json
• Domain: any Resend-verified domain (configured in your Resend account)
• Default from: set in credentials.json (e.g., noreply@yourdomain.com)

Receiving (Webhook + Clawdbot)

Use this when you want Resend inbound emails to trigger Clawdbot automatically.

1) Enable Clawdbot hooks

{
  hooks: {
    enabled: true,
    token: "<shared-secret>",
    path: "/hooks",
    transformsDir: "~/.clawdbot/hooks",
    mappings: [
      {
        id: "resend",
        match: { path: "resend" }, // relative to /hooks (no leading slash)
        action: "agent",
        deliver: true,
        channel: "telegram",
        transform: { module: "resend-inbound.js", export: "transform" }
      }
    ]
  }
}

Important: match.path is relative to /hooks (e.g., /hooks/resend → resend).

2) Expose the webhook (Tailscale Funnel)

If your gateway is local-only, expose it via Funnel:

/Applications/Tailscale.app/Contents/MacOS/Tailscale funnel --bg 18789

MagicDNS + HTTPS certs must be enabled in your tailnet for TLS to work.

3) Configure Resend webhook

In Resend → Webhooks:

• URL: https://<your-tailnet-host>.ts.net/hooks/resend?token=<shared-secret>
• Event: email.received

Resend cannot set custom headers, so use ?token=.

4) Fetch full email content

Resend webhooks do not include body text. Use the receiving API:

GET https://api.resend.com/emails/receiving/:id

(See resend-inbound.js for an example transform that fetches the body.)

Email Voice: The Bureaucrat

See references/voice-bureaucrat.md for the default email tone.

Key traits:

• Warm, patient, endlessly polite
• Passive voice ("it is recommended that…")
• Official jargon ("compliance framework", "pursuant to section 14(b)")
• Everything framed as "best practices"
• Bullet points start with "Please note that…"
• Ends with "We appreciate your cooperation"

Tone: DMV supervisor who smiles while denying your form × LinkedIn thought-leader who genuinely believes bureaucracy is beautiful.

When drafting emails, apply this voice unless instructed otherwise.

HTML Emails

curl -X POST 'https://api.resend.com/emails' \
  -H "Authorization: Bearer $RESEND_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "noreply@yourdomain.com",
    "to": ["recipient@example.com"],
    "subject": "Subject",
    "html": "<h1>Hello</h1><p>HTML content</p>"
  }'

Notes

• send.sh preserves line breaks in --body (no literal \n output).
• Use --html for rich formatting; default is plain text.

Common Patterns

Transactional notification:

# Order confirmation, welcome email, etc.
bash skills/resend-email/scripts/send.sh \
  --to "customer@example.com" \
  --subject "Your Request Has Been Processed" \
  --body "$(cat <<'EOF'
Dear Valued Individual,

It should be understood that all requests are handled in the order received, pursuant to our established compliance framework.

We appreciate your cooperation in maintaining an orderly process.
