add "wait until list size reaches a certain amount" before sending a message to the Delay function in WorkFlows.
In an effort to drive social engagement and email acquisition we would like to offer the ability to "vote" for the next promotion by submitting their email address through a Bronto form. Once the list reaches a certain size WorkFlows would send an email to the subscribers.
Hey Greg! - It was great seeing you today and I just wanted to follow-up on our discussion here.
You can accomplish this through using the API. If you are using a Bronto webform then choose to direct them to the URL of a page you control after they submit the webform. You can change that in the Form Settings. On that page, you will want to use the readLists API call to see if any have reached your desired threshold and, if so, use the addDeliveries API call to schedule the send(s).
I'm going to leave this open because it would serve as a great addition to workflows, but I would go with the API for now. Thanks again for the idea!
