The action allows you to select a pre-created mailingand start a one-time sending of a separate message of it.
Please note: this function is not intended to trigger mass mailings. When you start the action “Send mail by mailing” to a large number of users, the sending speed will be slow. To start mass mailings, it is necessary to configure inside the mailing list to whom and when to send it, and start it.
If the user has already received a message on this mailing list before, then for the repeated sending it is necessary to check the box “Send again if a message has already been sent to this object”.
