Hey Michael,
I downloaded your code and ran some tests and the issue indeed is that the <td> tags holding the content you see are not set to valign="middle" I did some restructuring and ran through a validator an all rendered appropriately. I don't see a way to reattach the code in this reply after my edits, but not sure that you would be able to overwrite your code in the editor with it and have the WYSIWYG editor still function. This is also why I haven't mentioned some other minor cleanup issues that WYSIWYG editors clutter in these auto-generated emails. Anyway, what you will have to do is go into your code and change the valign from "top" to "middle." You will have to change this in 6 <td> tags. 3 of which should be fairly easy to find, do a search for:
id="view47"
id="view52"
id="view56"
The <td>'s that contain those id's will house the "valign" attribute that needs to be changed. The other 3 <td>'s are nested within those, the structure will go <td><div><div><table><tr><td> for each of those 3. You will see other content inside those tags, but just ignore that stuff. Here is an example of 1:
<td valign="middle" align="left" rowspan="3" colspan="1" width="25" height="25" id="view52" style="">
<div id="sc5680" class="sc-view" style="left: 275px; width: 25px; top: 113px; height: 25px; overflow: hidden">
<div class="co-border-style" style="border-width: 2px; border-style: none">
<table width="25" height="25" cellspacing="0" cellpadding="0" border="0" bordercollapse="collapse" class="co-style-table" style="margin-top: 0px; margin-left: 0px; margin-right: 0px; margin-bottom: 0px">
<tr>
<td valign="middle" class="valign-able"><img width="25" height="25" src="http://img.en25.com/EloquaImages/clients/DocumentSystems/{0cf186f8-2bad-484f-92b6-5ed32fc876d8}_guide-2.png" title="" alt="" id="sc5682" class="sc-view sc-image-view editor-outline sc-regular-size" style="display: block"></td>
</tr>
</div>
</div>
</td>
That said, there are some other issues with this code. Did you at some point attempt to redo this code or somehow regenerate? For some reason there is a secondary email structure embedded within the initial email structure. I.E. your email is actually in the <head> tag of another empty email wireframe. More clearly said and hopefully more understandable, it's like the initial framework of an empty email was generated and then another email was generated within the <head> tag of that email, and that is the email code you are working in. If you know how, I would most definitely clear out that other wireframe framework, though it appears it doesn't seem to be causing any issues with rendering, I would be concerned about how SPAM filters would read that.
I will see if I can email you through your profile with an attachment and attach my edits for your reference. Hope this helps, and let me know if you hit a bump. Happy to help!
