not able to add icons to my email template


New Member
hello, I'm trying to add social media icons to my email template However, whenever I place my HTML CSS code to the source and then save the page and when the age gets refreshed the icons disappear in I don't understand why.

like this:

Before saving:
<div class="social-icons">

<a class="whatsapp-icon" href=""><i class="fab fa-whatsapp"></i></a>
<a class="telegram-icon" href=""><i class="fab fa-telegram-plane"></i></a>
<a class="instagram-icon" href=""><i class="fab fa-instagram"></i></a>
<a class="instagram-icon" href=""><i class="fab fa-tiktok"></i></a>
<a class="youtube-icon" href=""><i class="fab fa-youtube"></i></a>
<a class="email-icon" href=""><i class="far fa-envelope"></i></a>
<a class="website-icon" href=""><i class="fas fa-globe"></i></a>


After saving:

<div class="social-icons"> </div>

all the tags get disappear, any idea?
