Deliverr has recently announced that they will support international shipping, and Listing Mirror has the support for it that you need. You can edit each Deliverr integration to ship to the countries of your choice. This means you can now use Deliverr's fulfillment services for more orders! By leaving a country off of the "ship to countries" list, you can fulfill those using other services to save on shipping costs.
Find out more about this feature and how to edit your Deliverr integration here. All current Deliverr integrations will still only ship to US addresses, unless you go in and update the "ship to countries".
