A newsletter people join on its own page (cncto.co/n/) by confirming their address, like Buttondown or listmonk. Issues go out through the business's own email service (connect it first with newsletters_connect_service); every issue carries postal_address (the law in the US and the EU asks for one) and a one-click unsubscribe. Free; needs an account that has topped up once. Price: Free. A call that fails costs nothing. ## Use it when The business wants to write to people who asked for it, again and again. - For one email to one person or a few, use [email_send](https://conecto.chat/tools/email/email_send.md). ## Say this to your agent > Start a monthly newsletter called Halverson Ride Notes about new bikes, group rides and workshop news. ## Inputs | Name | Type | Required | Description | Allowed values | Default | |---|---|---|---|---|---| | `name` | string | yes | e.g. "Halverson Ride Notes". 1 to 120 characters. | | | | `postal_address` | string | yes | The business's postal address, shown at the foot of every issue. 10 to 300 characters. | | | | `description` | string | no | One or two lines on its page: what it is and how often it comes.

Conecto reviews the pause before sending resumes. | | `no_sending_service` | 409 | The business has not connected its own email service. | Connect it with newsletters_connect_service (its SMTP server, login and from address). | | `limit_reached` | 409 | The business has as many newsletters as it may. | Use one it already has. | The refusals every tool can give (401 key, 402 balance, 429 limits) are on the errors page: https://conecto.chat/docs/errors.md ## Related - [newsletters_connect_service](https://conecto.chat/tools/newsletters/newsletters_connect_service.md): Connects the business's own email service (Brevo, Amazon SES, Mailgun or any SMTP server), which every newsletter email goes out through.
