Strange or unexplained events. Say a delivery person hears unexplained noises from the place they are delivering to, or the recipient acts really oddly. For instance, the recipient stares blankly and doesn't respond to normal greetings. Another factor could be a sense of foreboding, like the delivery area has a reputation for being haunted or dangerous.
The setting can make it scary. For example, if it's at night in a deserted area. Like a delivery to an old factory in the middle of nowhere at midnight.
Well, the unexpected is often scary in delivery stories. Maybe the delivery address is wrong and leads to a really spooky place. Or perhaps the delivery person gets lost in a maze - like neighborhood that gives off an ominous vibe. Also, if there are things like strange markings on the package or the house looks like it has been in a horror movie, that can be really frightening.
