This guide covers USPS rules, packaging tips, and what to do if you're sending cards internationally. We'll also point out some great NSFW options from Exploding Kittens that are sure to get a laugh.
USPS Rules on NSFW Greeting Cards
The United States Postal Service (USPS) has regulations against mailing obscene material, but most NSFW greeting cards don't meet that legal threshold. Obscenity is defined by the Miller test, which considers community standards, patently offensive depictions, and lack of serious value. Most funny adult cards, even with crude humor, are protected speech.
However, USPS can inspect mail if there's reason to suspect illegal content. To avoid delays, ensure the card doesn't contain explicit sexual imagery or hate speech. If you're unsure, err on the side of caution and choose cards with suggestive but not explicit content.
- Check USPS Publication 52 for restricted items; most greeting cards are fine.
- If mailing internationally, research the destination country's customs rules—some countries have stricter standards.
How to Package NSFW Cards for Mailing
While the card itself is legal, how you package it can affect delivery. If you mail it in a standard envelope, postal workers won't see the content. But if it's a thicker card or you're including extras, use a padded envelope to prevent damage.
For extra discretion, place the card in a plain inner envelope before putting it in the outer one. This keeps the humor a surprise for the recipient and avoids any raised eyebrows during processing.
- Use a standard #10 envelope for single cards—no extra postage needed.
- For multiple cards, consider a flat rate envelope to keep costs down.
Choosing the Right NSFW Card for Mailing
When selecting a card to mail, consider the recipient's sense of humor and the occasion. For a birthday, the 'Facebook Kitty - Birthday Card' offers a funny twist on social media obsession, perfect for a friend who's glued to their phone. If you want something more universally hilarious, the 'Meteorite - NSFW Birthday Greeting Card' is a great choice.
Meteorite - NSFW Birthday Greeting Card

- Match the card's humor to the recipient's personality to ensure it lands well.
- If you're unsure about the tone, opt for a card that's more playful than explicit.
