You can mark your shipments as shipped in bulk by navigating to the Shipments page, and marking Selected shipments as shipped (all shipments you've selected by checking the checkbox next to them), or by marking Filtered shipments as shipped (all shipments in your current filter).
What happens if I mark my shipments as shipped?
We'll mark your shipments as shipped, and send out the shipment notification email to your subscribers, if you have that notification enabled.
How long will this take?
If you have hundreds or thousands of shipments to mark as shipped, this may take several minutes.
New, as of August 2017! The number of shipments marked as shipped will update in real time if you refresh the shipments page. For example, if you mark 5,000 unshipped shipments as shipped. If you refresh the page after a few moments, you might see the number of unshipped shipments go down to 4,800 shipments, then 4,600, then 4,400, etc.
How will I know when it's done?
You'll see a green notification pop up in the bottom right corner of the Shipments screen.
You can also turn on an admin notification called "Bulk Updates" by navigating to your Settings --> Notifications page, and by turning on the "Bulk Updates" notification.
