Email building - Wrap text

Hello!

I am building and email in Marketo and I am trying to get the text to wrap around an image and am struggling to do so without the text ending up completely broken up across the page. Am I missing something glaringly obvious or is it not possible to do this within the system?

I tried to do this through the alingment on the appreance tab for the image but it didnt seem to 'wrap', more a case of pushing letters around!

Hope this makes sense.

Thanks, Sarah
