## MCP tool

`manitu_webhosting_mail_mailinglist_recipient_add`

### Description for the model

Adds recipients to a mailing list of a web hosting package of the manitu customer account this connection works in, by site_id and mail_address from manitu_webhosting_mail_mailinglist_list. The recipients there stay; an address already on it is answered as unchanged. At most 1000 recipients per list (else a conflict, limit_reached). Refused per address that is none (mail_address_invalid) or the list itself (target_is_address_itself). The people added get every mail sent to the list - only with their consent: name every address to the customer and ask for an explicit yes first.

### Arguments

- `site_id` (integer | string, required) - The site_id from manitu_webhosting_list - never guess one. (pattern `"^[1-9][0-9]*$"`; minimum `1`)
- `mail_address` (string, required) - The address of the mailing list from manitu_webhosting_mail_mailinglist_list, e.g. club@example.de. Never guess one. (minLength `2`; maxLength `254`)
- `recipient_list` (array of string, required) - The addresses to put on the list. (minItems `1`; maxItems `1000`)
