Weekly new products automation using Shopify email app

[sfeller]

I would like to send an email every 7 days to subscribed customers highlighting new products added in the last 7 days. I thought this would be a basic marketing email and would be in the Shopify automation templates, but it is not. There is a New Arrivals template for email, but it is not automated.

I have tried creating a custom automation using workflow but can't seem to get it working. I sell one-off pre-owned items and add approx. 50 new items per week. Has anyone got an automation like this up and running? If so, please post the workflow used. Thanks!
