Contacts of the account, of one list or of one segment, with email, name and permission to send.

Constant Contact MCP tools: https://cotlet.dev/docs/mcp/constant-contact.md

MCP tool: `constant_contact_read → list_contacts`

Access: read.

Returns contacts one page per call; pass next_cursor back as cursor for the next page. Give list_id or segment_id to narrow it, not both. permission_to_send shows whether the contact can be mailed, with unsubscribed for contacts who opted out. Use contact_id in get_contact and add_contacts_to_list.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `list_id` | string | no | Only contacts of this list. |
| `segment_id` | integer | no | Only contacts of this segment. Do not combine with list_id. |
| `search` | string | no | Part of an email address or name. |
| `limit` | integer | no | How many items to return per page. |
| `cursor` | string | no | Next page cursor 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.
