Your artifacts post to Slack on a schedule
Schedule an artifact on a company's Slack connection, with your own intro and an Open artifact button.
Schedule a message on a company's Slack connection and Gatlas posts it at the time you set. Pick an artifact and Slack gets your intro with an Open artifact button, so a board pack can go out on the first of every month. Each message can post to its own channel. Whoever manages a company's Slack connection schedules its messages.
