Kassey here from the Shopify Guru Team! I just thought I'd let you know about Kit which is a virutal marketing assistant that works via app with Shopify! If you have the 29$/plan and up, Kit is actually free to start. Be sure to give it a look on the Shopify App Store page: (http://bit.ly/2rsqImB)!
