You might want to sign up for Informed Delivery from the USPS. It's free. They basically send you a B&W photo from the sorter machine of mail that's coming to your address. It's a good way to know if your mail has gone missing. I use it mostly because I don't get much junk mail and it saves me time from having to walk to the mail boxes at my apartment every night.

Are you creating an online appointment picker? Like https://appoint.ly/. Source: over 2 years ago

You might take a look at https://appoint.ly/ . I can't say for sure if it meets all of your needs in the free tier though, but if it's just one room, then it probably does. Source: about 3 years ago
