As a fresh freelance writer, you’ll often hear (read) the phrases “pitch a query letter” or “submit an LOI.”
These new terms are usually in the wealth of how to articles out there, and you might come to think that the terms query letter and letter of introduction (that’s what LOI stands for, by the way) are synonymous to each other—even synonymous in the way that you don’t know what they mean.
Just to be clear, these two don’t always mean the same thing.
