I have attempted to use Zapier to link the creation of a Trello board with the sending of a single Mailchimp campaign, but it does not work beyond the first use, because then the Mailchimp campaign would be concluded.
Is there a simpler way to do this? There just needs to be a way for someone to subscribe to a mailing list, and then whenever a Trello board is created in a specific list on a specific board, the contents of the Trello board, as well as the URL for accessing the Trello board is sent to the mailing list.
