We currently use a lot of headers but whenever we go tot he mobile version they all shrink down to awful sizes. Is there anyway I can edit the mobile version of our email so that I can insert different images that will be more appropriate for mobile viewing?
All of the current templates available in Emma accounts have mobile optimization built in. This means that they are coded to look just as good on mobile devices as they do on desktop. However, it appears that a few of your templates do not include the code for mobile optimization. I did a bit of research on your account, and I found that some of your templates were created by selecting 'Save As Template' on older Emma templates. These templates are missing the mobile optimization code, and are therefore unable to render correctly on mobile devices.
For example, you have a template called OCR WEEKLY 2017-2018 that was created from an older Emma template, and it does not have the correct code for mobile optimization. I created a mailing from this template, called Support Copy in your campaigns section, and I checked it out in Preview mode. It looks great in the desktop view, but in the mobile view the headers are cut off and the overall look is not as good. The same is true for the templates Spring 2014 Programs, Veterans, Diability, Distance Newsletter, and OCR Weekly Template. Due to the fact these templates were built off older Emma templates, you would need to create new templates to include the 'Mobile Query' code that allows for proper mobile rendering.
At this point, the best thing to do is to check your mailings, either through sending a test to a mobile device or by viewing the mobile version in Preview mode. If the mailing does not look correct in the mobile view, that template would need to be updated.
Please let me know if you have any further questions!
