 However, the advantage for a steamship carrying mail was that its arrival would be advertised in advance in the newspapers, thus giving it "free advertising" as a travel option for passengers or cargo.In most cases, mail carried by mail steamers was delivered to the post office to which it was addressed.In some cases, the incoming mail would be advertised in the local newspaper for pickup at the post office or at the steamship's office for a fee, if not already fee-paid.
