I currently send out html emails through my esp and do several rendering checks on all major isp's such as hotmail, gmail, yahoo etc.

The email renders fine in all inbox previews but I do not know a way to check how the email previews for mac users.

I found out recently that the emails render very poorly in macs with images breaking throughout the email.

I need to somehow be able to preview how the html will look like in a mac in order to test and fix these rendering issues
