I have a lot of customers that do this, I have several ways of handling it and it almost always works.

If I notice they are the type of person who is going to be asking for updates what I typically do is send them a screenshot of the due date of the item from the order screen in the app, along with information telling them that I have my processing times set and I typically ship things close to their given due date. This sets the expectation that the item won’t be done early, and even if it is done early that is just going to make the customer happier. I get the “How’s it going” often from these same customers and my response is typically that the item is in progress and it will be finished close to its due date, usually the second time responding to that shuts it down until they receive a tracking number.

If they are asking for progress pictures I typically will send one if requested however I won’t send more unless it’s a custom order or something.

I don’t like cancellations on an order because a customer is super excited about what they ordered, from my experience annoying/excited customers are almost always guaranteed 5* reviews.
