Final answer:
The most effective workflow for NTO would be two scheduled automations: one at 7:00 PM for sending shipping notices, followed by another at 9:00 AM 10 days later for sending customer surveys.
Step-by-step explanation:
The best workflow to enable Northern Trail Outfitters (NTO) to automate the sending of shipping notices and customer surveys would be:
Automation 1: Scheduled to run daily at 7:00 PM
Import File -> Filter -> Send Email
Wait 10 days (until the shipping date plus 10 days)
Automation 2: Scheduled to run daily at 9:00 AM
Filter (based on shipping date + 10 days) -> Send Email (Survey)
This sequence allows NTO to send the shipping notices once a day after the file is placed on the FTP after 4:00 p.m., and the customer surveys 10 days after the shipping date at precisely 9:00 a.m.
