When doing some email marketing campaigns or just sending out regular newsletters to your opt-in members, you may try to beautify your HTML email message to catch your readers’ attention much more. In my experienced, I even received emails in three or more column formats and images here and there especially if it’s endorsing some products.

Designing an HTML email that renders consistently across the major email clients can be very time consuming. Support for even simple CSS varies considerably between clients, and even different versions of the same client.

To save you time figuring out if your campaign renders the same in major email clients, CampaignMonitor has put together a guide to CSS support in email clients, both web-based and desktop apps. Unfortunately, Gmail (which I used for personal and business) has the most X‘ed on CSS support.
