Recipients of a campaign, searchable and filterable by what they did.

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

MCP tool: `mailshake_read → list_recipients`

Access: read.

Lists the recipients of one campaign, 100 to a page, with their custom fields and whether they are paused. filter_action keeps only recipients who opened, clicked, replied, were sent a message, bounced, are paused or have problems (a missing text replacement or a failed send). negate flips the filter, so opened with negate returns recipients who never opened. Pass next_token back for the next page.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `campaign_id` | integer | yes | Campaign ID from list_campaigns. |
| `filter_action` | enum | no | opened, clicked, replied, was_sent, bounced, paused or has_problems. |
| `negate` | boolean | no | true to find recipients who did NOT take the filter_action. Default: false. |
| `search` | string | no | Only recipients matching this name or email address. |
| `per_page` | integer | no | 1 to 100. Default: 100. |
| `next_token` | string | no | Next page token from the previous call. |

## 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.
