Periodically Sassie emails are delayed by days or weeks. This includes scheduling emails, assigned shop notification emails, and approval/return emails from editors. This is not the first time this has happened, and based on history, it won't be the last. Despite this being a legacy platform that has been around for decades, they still have not figured out how to stop this from happening. How many times have you heard someone complain on here that their shop was rejected because they needed to make corrections and never received the email?
Considering that Sassie owns Presto, and Presto has been and continues to be a dumpster fire of glitches, it is not surprising. Unfortunately, there really aren't a lot of options for MSC's. Shopmetrics, Sassie/Presto, and ISS app/website. They all have their plusses and minuses. These tend to be easier to use than the clunky proprietary platforms that some MSC companies use.
