Best Practice for Email Design and Html Coding

There are a few things to keep always in mind when designing Responsive HTML email Template:

• => Emails width should be within 600 to 650 pixels. This will make them behave better within the preview-pane size provided by many clients.
• =>  Avoid elements that require Flash or JavaScript. If you need motion in an email, a .gif is your best bet.
• =>  If it is possible to avoid background image, then it is good. Because some email clients will be initially blocked and some email clients will completely fail to load.
• =>  Email design is not Wed Design. Don’t design an email with sliced-up image. While these kinds of emails look pretty, they perform poorly.
• =>  Use basic, cross-platform fonts such as Arial, Verdana, Georgia, and Times New Roman.
• =>  For mobile screen use big call to action button.
