Hi,
This sounds like a confusing situation, especially since you’ve already turned off the common features that usually control expected delivery messaging.
Based on what you’ve described, here are a few things you might want to check:
1. Check your product settings for delivery customization
Sometimes, expected delivery messages are tied to individual product settings or overrides. Even if global settings are off, a product might still have delivery info attached if it was part of an experiment or test before. Go to the product page in the admin and scroll through to see if there’s any shipping or fulfillment section with a date range.
2. FedEx app connection may have triggered this
Even though your FedEx app is not being used for rate calculation, some apps (including carrier integrations) can inject delivery estimates into order details or customer-facing notifications. This can happen even if the shipping rate shown was a flat rate. It’s worth opening the FedEx app settings or checking whether it has permissions to edit delivery promises or tracking visibility.
3. Double-check the “Shop Promise” toggle under Shopify > Settings > Shipping and delivery > Delivery customization
Even if it says it’s off, Shopify has occasionally tested features in limited cases. You can try toggling it on, saving, and then turning it off again. This sometimes resets the expected delivery display logic.
4. Confirm whether the delivery date shows on customer emails or just inside the order view
If it’s only visible on the admin side, it might not affect the customer. But if it shows in confirmation emails or on the order status page, then it’s most likely tied to an integration or app that pushed the data through after checkout.
5. Check the Timeline inside the order
Inside the order page, scroll to the Timeline section to see if any app or automation has posted the delivery estimate there. It might show the source of where the estimate was added from.
This sounds like a one-off triggered by a mix of settings or app behavior. If it happens again with new orders, try keeping a record of which shipping method was selected, which app was active, and whether the product had any delivery info pre-set.
Hope this helps you narrow it down.
