## Connecting Claude or ChatGPT

### The connector address does not work

Use https://mcp.tellnod.com/mcp exactly. The address of a page on tellnod.com, such as tellnod.com/mcp-server, is not the connector address. Copy it from the Connect page and paste it into the connector’s URL field.

### Which Claude and ChatGPT plans can add Tellnod?

Claude on any plan, on the web or the desktop app: Free accounts can add one custom connector, and on Team and Enterprise an owner adds it. In ChatGPT, custom MCP servers are available on Business, Enterprise and Edu on the web, added by an admin or owner; OpenAI’s help article lists the current rules for each plan.

### Claude keeps asking me to sign in

Chats opened before you connected keep the old state, so start a new chat. If it still asks, open Settings → Connectors, disconnect Tellnod, click Connect again and choose the right Google account.

## Sending, bounces and unsubscribes

### Can anything send without my approval?

No. Preparing a send and confirming it are separate steps, and the confirm button is on the card, so the AI cannot press it for you. Every scheduled campaign can be cancelled until it goes out.

### What happens with bounces and unsubscribes?

Tellnod never emails people who unsubscribed or bounced. Unsubscribe links, one-click unsubscribe headers and your postal address are added to every campaign for you.

## Sender domain

### Do I need my own domain?

No. You can send from an address on our shared domain right away. For larger lists and the best inbox placement, we recommend verifying your own domain, which lifts the shared-domain limits.

### How do I verify my sender domain?

Ask Claude to add your domain. Tellnod gives you the SPF, DKIM and DMARC records to add at your DNS provider and checks them before your first send. It usually takes minutes and can take up to 48 hours.

## Billing and refunds

### Can I get a refund?

You can ask for a full refund of your first payment for a new paid subscription within 14 days of that payment, once per business. Renewal payments are not refundable. The refund policy has the details.

### Who processes my payment?

Dodo Payments is our reseller and Merchant of Record. It processes every payment, and every refund goes back to the original payment method.

### How do I cancel a paid plan?

Cancel at any time from the billing portal linked in your account, or write to contact@tellnod.com from the account holder’s email address. Cancel at least 48 hours before the renewal date to avoid the next charge. The plan stays active until the period ends, then the workspace moves to the Free plan and nothing is deleted.

## Account and data

### How do I delete my workspace and its data?

Ask in the chat or write to contact@tellnod.com. After you delete a workspace, we delete its content within 30 days, except database backups, which roll off within 7 days after that.

### How do I export my data?

Account holders can export workspace data by asking in the chat or by writing to contact@tellnod.com.

### I signed in with the wrong Google account

Your workspace belongs to the Google account you sign in with. In Settings → Connectors, open Tellnod and disconnect it, then click Connect again and choose the right account.
