Continuing with our Email Rendering series, let’s take a quick look at a few quirks that Yahoo! is known for. Much like Gmail, Yahoo provides two web based clients, Yahoo! Mail and Yahoo! Classic Mail. To change versions of Yahoo!, select from the “Options” drop down on the far right side of the screen.
Below are some great tips to consider when building your email campaign in order to create the best experience possible for Yahoo! subscribers.
Image Blocking - Alt Tags
Images are blocked by default in Yahoo!. However, Yahoo! does display stylized “alt” tags, so add those to your design when it makes sense to help create brand synergy.
You can always edit this image-blocking feature in your Mail Options. There are a few choices, “Always show images…”, “Show images only from my contacts”, or “Initially block images”. Personally, I have them turned on by default – but many of your subscribers may not, or may not even know they can edit this feature.
While no Email Service Provider can enable your images to display in an email client that blocks display, services such as Goodmail or CertifiedEmail™ allow email marketers to pay a per-message fee to deliver emails with “images on” to AOL, BT and Yahoo!.
Avoid Paragraph Tags
Yahoo! Mail and Yahoo! Mail Classic do not support the use of HTML paragraph tags <p>. Paragraph tags are used primarily to create space between sections of text. If two sections of text are each contained within paragraph tags the space that normally appear between the paragraphs will not be seen. In order to avoid this, break tags <br> can be used. Two break tags in a row will create the same amount of space between text sections as a paragraph tag.

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.
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.
