This week we’re focusing on email rendering in Gmail. Gmail, like other web-based email clients, is constantly evolving. These updates continually change the way HTML emails are rendered. Not only do email designers need to pay special attention to Gmail, they need to be aware that their Gmail subscribers may be seeing one of two different versions of Gmail. Depending which browser and version you are using, scroll to the bottom of your account and select the “older version” link to test that version of Gmail. To revert back to the newest version, select the “newer version” link in the top right section of the account. Below are some great tips to consider when building your email campaign in order to create the best experience possible for Gmail subscribers.
Image Blocking - Alt Tags
Images are blocked by default in Gmail. Gmail does display stylized “alt” tags, so add those to your design when it makes sense to help create brand synergy.
CSS
In both versions of Gmail, CSS must be applied inline. External or embedded CSS in the head of the HTML will be stripped out.
CSS Borders
The newer version of Gmail has difficulty rendering CSS borders in IE8. Occasionally, 1-2 pixels of white space will be added to the left or right side of the content enclosed within the border. This issue affects some designs more than others, so if you have a particular element that depends on symmetry, test both old and new Gmail versions to ensure your design renders properly. If CSS borders are giving you trouble, you may want to consider using a background color combined with a spacer .gif to create the same look.
Background Images
Background images are supported in both versions of Gmail. However, the “background-image” CSS property is not supported, so the HTML “background” attribute must be used to assign a background image. Previously, there were issues using the CSS property “background-repeat”, but that property is also now currently supported.
Gmail Themes
Gmail introduced the concept of “themes” this year, which allow the user to select different combinations of background colors, text and link colors to personalize their inbox. Some combinations may render light text on a light background, or dark text on a dark background. The bottom line: you must specify background, text, and link colors in your HTML, or they may be changed in accordance with your subscriber’s Gmail Theme.
Testing
Always be sure to test in major web browsers like Internet Explorer and Firefox, and remember that there are both newer and older versions of Gmail. Gmail is a great client to test first when finishing your campaign, as it exposes rendering problems and is unforgiving of any HTML syntax errors.
Personally, I love using Gmail — it has great features including shared docs, calendars, folder organization tools and other interactive capabilities, so let's make sure our subscribers continue to have a great experience in Gmail.

I don't know about you, but I like to enjoy each holiday on its own and in order. Especially in the Fall when the three big holidays come hurtling at you back to back from the dark days of Fall: Halloween, Thanksgiving and Christmas. I don't put out Halloween decorations until October, I don't buy a turkey until November and I don't really start planning for Christmas until after Thanksgiving. I definitely do not shop for Christmas presents in July! Who really does that anyway? 
Wednesday was the first day of Fall - the Autumnal Equinox. It's funny...one would think that when the weather starts to cool down and the days become shorter that things would start to slow down. But quite the opposite happens. Fall is the time for holidays and holiday planning - Halloween, Thanksgiving, Hannuka, Christmas and New Year's Eve - parties, open houses, pitch-ins...you name it. They come at you fast and furious and before you know it kids are at your door looking for candy...while you sit inside your house in the dark hoping they go away because you hadn't planned ahead and bought any candy. That doesn't even take into account all the fall cleanup that usually happens in and around the house.


Back to School brings back many wonderful memories...crisp autumn air, new clothes, and football. It also brings back memories of homework. Homework methodology varies from student to student. There are the procrastinators that wait until the very last second to complete their homework. Many live by the "all-nighter" rule whether prepping for exams or writing a thesis on "Great Expectations". Then there are those that are completely organized. They have their #2 pencil and pink pearl eraser ready to tackle each and every assignment in precise order - starting at the top of the list of subjects with Physics or Calculus.
One of my goals for this blog was to share email marketing success stories from some of our small-to-medium size business customers. In keeping with last week's "Back to School" theme, I especially love stories where success was derived from getting back to basics.
