Please confirm to release the shipment
Need "the" or can "omit"? Thanks to advise.
Please confirm [in order] to release the shipment.
However, if it's perhaps just at the bottom of a document where someone has to sign to confirm, then we might see simply:
[Please] confirm to release shipment.
Please remember to use full sentences in your posts though. "Need "the" or can omit?" is not a complete sentence. See my changes to your post in red above.
