Email automation triggers with a date range

[AP19]

Hi, 

We want to set up an automation in Shopify Email that checks if an order has been placed in the last X (say, 7) days before sending the email. The flow should ideally be: Order fulfilled > wait 60 days > check if order placed in last X days > if not, send email

The issue we're facing is that we need to choose a specific date for the 'order created' variable and not a date range. Is there some way such automations can be set up? We're very new to Shopify Email and any guidance would be great. 

Thanks in advance!

Thank you, this really helps. Coding doesn't seem like a viable option, so we will figure out the best 3rd party app option for our business. 

Thanks again!
