"School Forms" question

<p>Hi, i've been searching through threads try to find this answer but I haven't found it and I'm a bit confused.
I gave my teachers everything they need to write recommendations and they are all gunna send it by mail. But apparently the common app says that I need to invite them or something and it requires their email and name and everything.
Do i still need to write this out even though they are already going to send it by mail?
thanks</p>

<p>Fill out their name and subject but leave the email BLANK. Then you’ll see it says “Mr. Whoever has chosen to submit his recommendations by mail…” blahblah and you can add him(/her) to a college.</p>

<p>that makes sense. thank youu</p>
