We've added a new marketing automation. Our art alerts feature has, historically, only sent a notices to collectors following you if you upload new art. If you enable the new "Promote Mode" we will send an alert of your oldest piece after two weeks of inactivity on your account. That is, if you don't upload art in a two week period, we will automatically send an alert of your oldest artwork to keep you and your art top of mind with your followers. It is likely that many of your followers will not have seen your oldest work and this could potentially lead to sales.

This setting can be changed in the settings drop down -> Account Settings -> Settings -> Edit next to "New Art Alert Promote Mode" (Under Marketing Heading)
