U+1F4E4 · emoji since 2010
The outbox tray with an up arrow means mail going out. It marks sent messages, uploads, and things on their way.
It is the icon for sent, the tray where everything you fire off lifts up and heads out.
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 Outbox Tray emoji. In everyday chat most people just call it the outbox tray 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.
