Can I send transactional emails with the Resend node?

Yes. The send-email operation delivers an email with an HTML or plain-text body, CC, BCC, and reply-to addresses. The sender must be on a domain you have verified in Resend.

Can I schedule emails to send later?

You can. The send-email operation accepts a scheduled time written in natural language, such as in 1 hour, or as an ISO 8601 timestamp. Scheduled emails can also be rescheduled or cancelled later.

Can a workflow react to email events from Resend?

Yes. The receive-webhook operation works as a trigger and fires on events like delivered, bounced, opened, and complained, so your workflow can respond to what happens after an email is sent.

How do I check whether an email was delivered?

Use the get-email operation with the ID returned when the email was sent. It returns the current status and details so a later step can branch on whether delivery succeeded.

What do I need to connect Resend?

You need a Resend API key, which starts with re_ and is created on the Resend API Keys page. Add it as the credential on the node and you can start sending email immediately.

Hermes is an open agent based on Nous Research’s Hermes models. NoClick runs it for you and adds your connected apps as tools.

How do I give Hermes access to an app?

Connect the app's integration node to the agent's tools handle and pick the operations to expose. Each becomes a callable tool.

Do I need my own infrastructure?

No. The harness runs in a hosted sandbox and NoClick handles credentials for the apps you connect.

Can Hermes use multiple apps at once?

Yes. Wire in several integrations and the agent can use them together in a single run.

Connect Hermes to Resend

Connect an AI agent to your Resend account as a tool and it sends and manages email itself instead of describing the send. It can send an email, look one up, reschedule a scheduled send, cancel one before it goes out, and receive webhook events, calling each operation as a tool while it works. In NoClick it connects to a hosted coding agent that can run a full send-and-follow-up loop without you touching the dashboard.

What happens next

Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:

Choose where it runs
On your computer through your own Hermes, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Resend
A preset of real Resend operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Resend
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Hermes first calls in. Hermes connects when it next starts a session.
1. Run this in your terminal
$hermes mcp add noclick --url https://mcp.noclick.app/s/<your-link>
2. Answer no when asked if the server requires authentication — the link itself is the key
<your-link> is your personal server URL — setup mints it for you.
