U+1F4E8 · emoji since 2010
The incoming envelope is mail flying toward you, a message arriving. It means new email, a notification, or a note on its way.
It marks fresh messages and invites landing in your inbox, the cheerful icon for you've got something.
In texting, 📨 does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and 📨 is not really one of them.
Its official Unicode name is the Incoming Envelope emoji. In everyday chat most people just call it the incoming envelope emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The 📨 leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
Or make your own cipher in the translator.
