Stop or restart the emails of one recipient in one campaign and keep the rest of the campaign running.

Mailshake MCP tools: https://cotlet.dev/docs/mcp/mailshake.md

MCP tool: `mailshake_write → pause_recipient`

Access: write.

Pauses one recipient in one campaign by email address, or unpauses them with paused false. An email being sent at that moment is not stopped. A reply stops follow-ups but not drip emails, so this is how you stop a drip for someone who booked a meeting. Unpausing reschedules their pending emails. It reaches no one and one more call reverses it, so it does not wait for your OK. A recipient not in the campaign comes back as not_found.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `campaign_id` | integer | yes | The campaign the recipient is in. |
| `email_address` | string | yes | The recipient's email address. |
| `paused` | boolean | no | true to pause, false to unpause. Default: true. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
