There are moments when you do not want a heart-to-heart. You want results. You want the late-night bass to quiet down, the shared fridge to stop disappearing snacks, the coworker to retire the fish-in-the-microwave routine. Petty Parcel gives you a clean, legal, memorable way to say the thing without starting World War III. Think of it as classy catharsis by envelope.
We’re a funny anonymous mail service that prints your message on real paper, slips it into a distinctive envelope, and drops it in the mailbox without your name attached. Our tone options keep the message firm but humane, our moderation keeps it safe and lawful, and our ops keep it simple.
Digital messages are easy to ignore. Physical mail lands with a thud of seriousness. It gets opened. It gets read. It gets remembered.
High open rate: A tangible envelope creates curiosity and a touch of accountability.
Non-confrontational: No face-to-face arguing, no instant reply spiral.
Documented nudge: A physical reminder nudges behavior far better than another text.
If you have searched “send anonymous letter to neighbor” or “how to complain anonymously by mail,” you already know there are times when a note in the mailbox beats a note in the group chat.
Sending an anonymous letter is generally legal in the U.S. when the content is lawful. A return address is usually not required for First-Class letters. That is why people search how to send mail without return address and discover it is a real thing. Certain mail classes or services do require return addresses, and undeliverable items without one may be discarded by USPS rather than returned.
True threats or intimidation
Harassment or stalking (repeated, targeted communications designed to alarm)
Hate speech or discriminatory content
Doxxing or sharing private personal data
Blackmail, extortion, or defamation
Obscene materials or anything that violates USPS non-mailable rules
We enforce these rules with automated screening and human review. If a message crosses a legal or ethical line, we do not print it and we notify you to revise. This is how a passive aggressive mail service stays both funny and functional.
You could print your own letter. You could also cut your own hair. Sometimes outsourcing is smarter.
Anonymity handled: We know where anonymity fails and how to prevent it.
Formatting done right: Clean fonts, clean layout, readable tone.
Moderation built in: We keep you out of trouble and your message in bounds.
Memorable presentation: Our envelope design is distinct and instantly attention-worthy, without being clownish.
Fast fulfillment: We print quickly to catch the moment while it matters.
