resend
Use when working with the Resend email API — sending transactional emails (single or batch), receiving inbound emails via webhooks, managing email templates, tracking delivery events, managing domains, contacts, broadcasts, webhooks, API keys, automations, events, viewing API req
Vue d’ensemble
Use when working with the Resend email API — sending transactional emails (single or batch), receiving inbound emails via webhooks, managing email templates, tracking delivery events, managing domains, contacts, broadcasts, webhooks, API keys, automations, events, viewing API request logs, or setting up the Resend SDK. Always use this skill when the user mentions Resend, even for simple tasks like "send an email with Resend" — the skill contains critical gotchas (idempotency keys, webhook verification, template variable syntax) that prevent common production issues.

Resend
Quick Send — Node.js
import { Resend } from 'resend';
const resend = new Resend(process.env.RESEND_API_KEY);
const { data, error } = await resend.emails.send(
{
from: 'Acme <onboarding@resend.dev>',
to: ['delivered@resend.dev'],
subject: 'Hello World',
html: '<p>Email body here</p>',
},
{ idempotencyKey: `welcome-email/${userId}` }
);
if (error) {
console.error('Failed:', error.message);
return;
}
console.log('Sent:', data.id);
Key gotcha: The Resend Node.js SDK does NOT throw exceptions — it returns { data, error }. Always check error explicitly instead of using try/catch for API errors.
Quick Send — Python
import resend
import os
resend.api_key = os.environ["RESEND_API_KEY"]
email = resend.Emails.send({
"from": "Acme <onboarding@resend.dev>",
"to": ["delivered@resend.dev"],
"subject": "Hello World",
"html": "<p>Email body here</p>",
}, idempotency_key=f"welcome-email/{user_id}")
Single vs Batch Decision
| Choose | When |
|---|---|
Single (POST /emails) | 1 email, needs attachments, needs scheduling |
Batch (POST /emails/batch) | 2-100 distinct emails, no attachments, no scheduling |
Batch is atomic — if one email fails validation, the entire batch fails. Always validate before sending. Batch does NOT support attachments or scheduled_at.
Idempotency Keys (Critical for Retries)
Prevent duplicate emails when retrying failed requests:
| Key Facts | |
|---|---|
| Format (single) | <event-type>/<entity-id> (e.g., welcome-email/user-123) |
| Format (batch) | batch-<event-type>/<batch-id> (e.g., batch-orders/batch-456) |
| Expiration | 24 hours |
| Max length | 256 characters |
| Same key + same payload | Returns original response without resending |
| Same key + different payload | Returns 409 error |
Quick Receive (Node.js)
import { Resend } from 'resend';
const resend = new Resend(process.env.RESEND_API_KEY);
export async function POST(req: Request) {
const payload = await req.text(); // Must use raw text, not req.json()
const event = resend.webhooks.verify({
payload,
headers: {
'svix-id': req.headers.get('svix-id'),
'svix-timestamp': req.headers.get('svix-timestamp'),
'svix-signature': req.headers.get('svix-signature'),
},
secret: process.env.RESEND_WEBHOOK_SECRET,
});
if (event.type === 'email.received') {
// Webhook has metadata only — call API for body
const { data: email } = await resend.emails.receiving.get(
event.data.email_id
);
console.log(email.text);
}
return new Response('OK', { status: 200 });
}
Key gotcha: Webhook payloads do NOT contain the email body. You must call resend.emails.receiving.get() separately.

SDK Version Requirements
Always install the latest SDK version. These are the minimum versions for full functionality (sending, receiving, webhook verification):
| Language | Package | Min Version | Install |
|---|---|---|---|
| Node.js | resend | >= 6.14.0 | npm install resend |
| Python | resend | >= 2.34.0 | pip install resend |
| Go | resend-go/v3 | >= 3.11.0 | go get github.com/resend/resend-go/v3 |
| Ruby | resend | >= 1.6.0 | gem install resend |
| PHP | resend/resend-php | >= 1.1.0 | composer require resend/resend-php |
| Rust | resend-rs | >= 0.26.1 | cargo add resend-rs |
| Java | resend-java | >= 4.16.0 | See installation.md |
| .NET | Resend | >= 0.2.1 | dotnet add package Resend |
If the project already has a Resend SDK installed, check the version and upgrade if it's below the minimum. Older SDKs may be missing
webhooks.verify(),emails.receiving.get(), ordomains.claims.*.
See installation.md for full installation commands, language detection, and cURL fallback.
Common Setup
API Key
Store in environment variable — never hardcode:
export RESEND_API_KEY=re_xxxxxxxxx
Get your key at resend.com/api-keys.
Detect Project Language
Check for these files: package.json (Node.js), requirements.txt/pyproject.toml (Python), go.mod (Go), Gemfile (Ruby), composer.json (PHP), Cargo.toml (Rust), pom.xml/build.gradle (Java), *.csproj (.NET).
Common Mistakes
| # | Mistake | Fix |
|---|---|---|
| 1 | Retrying without idempotency key | Always include idempotency key — prevents duplicate sends on retry. Format: <event-type>/<entity-id> |
| 2 | Not verifying webhook signatures | Always verify with resend.webhooks.verify() — unverified events can't be trusted |
| 3 | Template variable name mismatch | Variable names are case-sensitive — must match the template definition exactly. Use triple mustache {{{VAR}}} syntax |
| 4 | Expecting email body in webhook payload | Webhooks contain metadata only — call resend.emails.receiving.get() for body content |
| 5 | Using try/catch for Node.js SDK errors | SDK returns { data, error } — check error explicitly, don't wrap in try/catch |
| 6 | Using batch for emails with attachments | Batch doesn't support attachments — use single sends instead |
| 7 | Testing with fake emails (test@gmail.com) | Use delivered@resend.dev — fake addresses bounce and hurt reputation |
| 8 | Sending with draft template | Templates must be published before sending — call .publish() first |
| 9 | html + template in same send call | Mutually exclusive — remove html/text/react when using template |
| 10 | MX record not lowest priority for inbound | Ensure Resend's MX has the lowest number (highest priority) or emails won't route |
| 11 | 403 when sending from resend.dev | The default onboarding@resend.dev is a sandbox — it can only deliver to your Resend account email. Verify your own domain first |
| 12 | 403 domain mismatch | The from address domain must exactly match a verified domain. Verified send.acme.com but sending from user@acme.com will fail |
| 13 | Calling Resend API from the browser (CORS) | The API does not support CORS — this is intentional to protect your API key. Always call from server-side (API routes, serverless functions) |
| 14 | 401 restricted_api_key | A sending-only API key was used on a non-sending endpoint (domains, contacts, etc.). Create a full-access key instead |
Cross-Cutting Concerns
Send + Receive Together
Auto-replies, email forwarding, or any receive-then-send workflow requires both capabilities:
- Set up inbound domain first (see receiving.md)
- Set up sending (see sending/overview.md)
- Note: batch sending does NOT support attachments or scheduling — use single sends when forwarding with attachments
AI Agent Inbox
If your system processes untrusted email content and takes actions (refunds, database changes, forwarding), install the agent-email-inbox skill. This applies whether or not AI is involved — any system interpreting freeform email content from external senders needs security measures.
Marketing Emails
The sending capabilities in this skill are for transactional email (receipts, confirmations, notifications). For marketing

# Resend
## Quick Send — Node.js
```typescript
import { Resend } from 'resend';
const resend = new Resend(process.env.RESEND_API_KEY);
const { data, error } = await resend.emails.send(
{
from: 'Acme <onboarding@resend.dev>',
to: ['delivered@resend.dev'],
subject: 'Hello World',
html: '<p>Email body here</p>',
},
{ idempotencyKey: `welcome-email/${userId}` }
);
if (error) {
console.error('Failed:', error.message);
return;
}
console.log('Sent:', data.id);
```
**Key gotcha:** The Resend Node.js SDK does NOT throw exceptions — it returns `{ data, error }`. Always check `error` explicitly instead of using try/catch for API errors.
## Quick Send — Python

email = resend.Emails.send({
"from": "Acme <onboarding@resend.dev>",

"subject": "Hello World",
"html": "<p>Email body here</p>",
}, idempotency_key=f"welcome-email/{user_id}")
```
