Hi AoC Devs, not sure if you send your emails through Klavio or whatever you use for email marketing.
Your emails currently look like the image below on iOS mobile devices, which can hurt performance due to difficulty in readability. It makes font size even smaller than it should be.
Use script below instead for full bleed emails on iOS devices. Just looks better and cleaner

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" name="x-apple-disable-message-reformatting"/>
<STYLE type="text/css">
.ReadMsgBody{
width: 100%;
}
.ExternalClass {width: 100%;}
.ExternalClass * {line-height: 100%;}
</STYLE>
