Is anyone aware of a way to utilize a 'preheader' within an email delivery? I am unable to find any documentation so i'm assuming Adobe has a different name for it.
For reference here is a fairly succinct definition:
A preheader is the short summary text that follows the subject line when an email is viewed in the inbox. Many mobile, desktop and web email clients provide them to tip you off on what the email contains before you open it.
There is no place in the UI that I can think of to apply it. We just go into the SOURCE tab in the bottom left of the delivery to edit the HTML. Or Before you upload the HTML you can apply it in the HTML editor then upload it.
Here is where we put the preheader. Right after the closing body tag.
<span style="display: none !important; mso-hide:all;">HERE IS SOME PREHEADER TEXT</span>
It didn't work after the closing body tag, but it did work if we put it just after the body open tag if we removed the mirror page link (which is before the doctype). With the mirror page element in place though, we needed to place that code above it.
