Send and receive email from n8n
Give n8n a real email address. ThreadCamp provides programmatic inboxes, Resend-compatible sending and forwarding Routes through one REST API and an MCP server - so n8n can send, receive OTPs and hold conversations.
Call the REST API
n8n can call any HTTP endpoint, so integrate ThreadCamp with a single request to the REST API. Use a scoped API key and POST to /v1/emails to send, or /v1/inboxes to create an inbox:
// Send email from your workflow via the REST API
await fetch("https://threadcamp.vercel.app/v1/emails", {
method: "POST",
headers: {
Authorization: "Bearer sk_live_...",
"Content-Type": "application/json",
},
body: JSON.stringify({
from: "agent@acme-agents.email",
to: ["customer@example.com"],
subject: "Hello from your workflow",
text: "Sent via ThreadCamp.",
}),
});Receive and forward, not just send
Sending is only half the loop. Create an inbox with POST /v1/inboxes to get a real, addressable mailbox with threads. Inbound mail arrives over HMAC-signed webhooks or polling, and per-domain Routes can forward mail - with SRS so SPF and DMARC survive - to another address, a webhook, or straight into a ThreadCamp inbox that n8n can reply on.

Questions
How do I add email to n8n?
Use the ThreadCamp REST API from n8n. POST /v1/emails sends mail, POST /v1/inboxes creates a real inbox, and Routes forward inbound mail to a webhook you handle in n8n.
Can n8n receive replies, not just send?
Yes. Create an inbox with POST /v1/inboxes and read inbound mail via HMAC-signed webhooks or polling. Threads and messages are first-class objects, so n8n can send, receive and forward under one key.
Give n8n an inbox in the next minute.
