The U.S. Postal Service might soon be one of several entities with access to your mailboxes.

A proposal from President Donald Trump calls for letting others, such as Amazon, UPS and FedEx, gain entry — for a fee.

It's one of several suggestions aimed at helping the U.S. Postal Service improve its bleak financial outlook, according to CBS News.

The agency has reported 12 straight years of losses and is bleeding cash.

Other suggestions include charging more for so-called "non-essential services," such as delivering advertising flyers.

The report doesn't say how much money the U.S. Postal Service could make by implementing some or all of the suggestions.

Some critics, though, say the plan could backfire and actually wind up costing the agency even more, CBS News reported.
