Use of foreshadowing is key. Drop little hints in the preview about something bad that might happen. For instance, a character might mention a local legend that seems to be coming to life.
Slowly revealing information helps. Don't give away too much at once. Maybe show a strange object in the preview but don't explain what it is or what it does. This makes the audience curious and a bit scared as they try to figure it out.
Building a sense of isolation for the characters can create suspense. If in the preview, the characters are in a place far from help, like a remote island or a locked room in a creepy old house, it makes the viewer wonder how they will get out and what will attack them while they're trapped.
