Hey Kelsey!
Recently I've begun to write my address and email on the back of my letters

I don't really expect an email from them but it's just in case. And I write my address so in case the letter gets separated with the SAE he/she can easily find it

Also, I write my address and email lightly
in pencil at the back of my photos so that they don't get lost or mixed with other people's either!
Good luck! {thumb2}
