Dispatch Request

A person wants something from a distance, like when you ask a friend in another city to bring you a specific snack when they come over, so you use the envelope and arrow to show the request and the direction it needs to travel

The emojis feel like a quiet message between two people who can't talk openly, like when someone drops a hint in a group chat that they need support or a favor, but only one other person should notice

When you're trying to keep track of all the things you need to get done, this emoji feels like a reminder that you've sent a request and just need to wait for it to come back to you, like a to-do list that's been handed off to someone else

In some families, especially when relatives live far apart, this emoji is like a way of saying 'we need you to bring something over here' without being too direct, like when you ask an aunt to mail you a recipe your grandmother used to make

Younger people using these emojis might be trying to sound like their older relatives who use mail-order catalogs, but in a more modern, digital way, as if they're placing an order for something simple but with lots of ceremony
