sending letter of recommendations

Applying to College Common and Coalition Application

<p>I'm confused about this thing.</p>

<p>Should my teachers send the letter of recommendation online or paper? I'm asking because my teachers don't have official school email IDs? how the universities are going to consider this thing? of course sending LORs are costly. and online submission can save me a lot of money.
please clarify this thing.</p>

<p>Official school email addresses are not required for teachers to participate in the online recommendation process. You can add them as recommenders through the common app site and they can submit their recommendations electronically through the common app site from any valid email address.</p>
