HTML GUIDELINES
- Material must be supplied complete in HTML code format, which has been specifically designed for email (i.e. not a webpage).
- The HTML and CSS should be coded by hand to ensure clean, compact code.
- Please do not use Word's 'Save As HTML' feature, and we recommend you do not use Microsoft Frontpage or any other “free” or WYSIWYG web design software, as these frequently insert unnecessarily verbose, or ‘illegal’ coding.
- Do not use global CSS selectors, nor a locally saved stylesheet (i.e. C:/My_Documents/my_stylesheet.css) - use inline styles only. Many popular ISP’s strip out CSS anyway. (e.g. of inline styles. <p style="color:sienna;margin-left:20px;">This is a paragraph.</p>)
- Characters used must be from the US-ASCII character set printable characters 0-127. For characters outside this range use a suitable replacement (i.e. “escape” them). For example, two dashes for one em-dash, or © for ©.
- Always specify alt text for images that have a context or meaning important to the campaign message or desired action. For unimportant images used for decoration only set alt="".
- Link all images and URLs.
- Do not use CSS absolute positioning, divs or layers as these features are not supported by some email clients. While not recommended for Web pages, tables are still the best way to lay out HTML emails, and it is a good practice to insert a line break for every closing </TD>, </TR>, </Table> tag.
- Do not use Java, Javascript, forms, frames, ActiveX, animated GIFs or Flash.
Scripts will be treated as SPAM by most ISP’s, and you will most likely not reach your recipients.
The Client explicitly agrees that animated .gif’s (where used) can display at any frame of your animation with some ISP’s. This is beyond Yaffa’s control, and if you have concerns, please use a static image instead.
- Use background images as secondary design elements, as they will not display in some email clients.
- Do not use image maps.
- Do not use <body > tag attributes (esp. bgcolor, background, etc.) and do not apply any markup or styles “in the section. Web-based email clients will often filter out this code.
- Images can be hosted externally (use 'absolute' full URL, image references in the HTML) or supplied in a zip archive (use 'relative' references in the HTML).
- Max design width of 600 pixels will work best. Consider those recipients who open/click/transact on mobile devices.
- Total package size should not exceed 5MB
