Golang sql named parameter query

I am trying to use named parameter query in golang as follows:

stmt, err := db.Prepare("insert into users(name, email) values(@name, @email)")
if err != nil {
    //error handling
}

res, err := stmt.Exec(sql.Named("name", name), sql.Named("email", email))

if err != nil {
        //error: sql: expected 0 arguments, got 2 
}

I get the following error: "sql: expected 0 arguments, got 2".

What is correct way to write this query?
