Html For Email - Technical Tips and Tricks Developing Emails
- 1. HTML FOR EMAILTechnical Tips and TricksDeveloping Emails
- 2. HTML FOR EMAIL: GENERAL RECOMMENDATIONSHTML for email is different than HTML for the web!Modern web design utilizes CSS (cascading style sheets) for layout. However, due to inconsistent CSS support, HTML tables must be used for email layout. CODE LIKE IT’S 1999!No standards exist for displaying HTML in email.Proper syntax still counts – use a validator to check for general errors.Make sure all open tags have a properly nested closing tag.Specify accurate table and cell widths. Improper math can cause major layout problems.Images & other elements should each reside in their own table cell.Specify desired alignments (left, right, top, bottom). If unspecified, not all email clients will default to the same alignment.
- 3. What elements are supported in email?HTML FormsUsed for surveys, search wizards, drop-down boxes, etc.
- 4. About half of email clients either disable forms or display a warning message about the form, leading to a poor user experience
- 6. Link to a survey / form hosted on an external landing page
- 7. Provide a link near the form that allows subscribers to view the email in their browser
- 8. Use images to create a simple survey and pull results from click trackingWhat elements are supported in email?Video and FlashEmbedding Flash or video in an email can cause deliverability issues, and if delivered, video will be disabled in almost every email client.
- 9. Supported ways to use multimedia with email
- 10. Use a still image to link to a video hosted on a landing page
- 11. Use an animated .gif (see below)
- 12. Certified Video from Goodmail(currently only supported in AOL; higher production and delivery costs) Animated .gifsSupported in most email clients
- 13. Poor image quality and potential for large file size
- 14. No audio or playback controls
- 15. Use caution in Outlook 2007 – only the 1st frame will display, so make sure the 1st frame conveys your message. Include a play button on 1st frame and link the .gif.What elements are supported in email?JavaScriptNot supported in any email clients
- 16. Can cause emails to end up in the junk/spam folderBackground ImagesBackground images should be added using the HTML background attribute
- 17. Background images will not display in Outlook 2007 and Lotus Notes, regardless of the method of application
- 18. Text over a background image must be readable on the background color - background images are not supported in all clients and images may be turned off.TOOLS FOR CREATING HTMLHTML EditorsHTML editors such as Dreamweaver, Microsoft Office SharePoint Designer, etc. are designed with web coding in mind, not email.
- 19. Many of the coding techniques used in HTML editors will lead to display issues in email clients - Microsoft Word, for example, will add proprietary code that will not display properly
- 20. To achieve the best results use a plain text editor such as Notepad or TextEdit
- 21. Other options available for download include:
- 22. Windows - E Text Editor, Notepad++
- 23. Mac – TextMate, Coda
- 24. Windows/Mac/Linux - Komodo EditImage EditorsWindows/Mac – Photoshop, GIMP, photoshop.com
- 25. OUTLOOK 2007 Avoid Background Images – include them only as secondary elements.
- 26. Avoid using CSS margins – use CSS padding or spacer .gifs to create spacing between elements.
- 27. Forms do not work in Outlook 2007.
- 28. Outlook 2007 is very particular. Specify accurate table widths – errors in math will cause incorrect display.
- 29. Outlook 2007 is very particular. Specify accurate colspans and rowspans – extra values creates extra spaces.
- 30. Only the first frame of an animated .gif will display, so make it count.
- 31. Only in Outlook 2007: CSS padding applied to the top or bottom on one cell in a multi-column layout will be applied to all columns in that row<table border=“0” cellpadding=“0” cellspacing=“0” width=“100%”> <tr> <td style=“padding-top: 10px;”>Left Column</td> <td>Right Column</td> <!-- The right column will ALSO have 10px of padding-top in Outlook 2007 --> </tr></table>LOTUS NOTES & HOTMAILLotus NotesSince Notes is very challenging to code for, make sure Notes users make up a significant portion of your audience before reconfiguring your code specifically for this environment.
- 32. Notes only supports nesting 8 tables deep
- 33. Specify defined widths wherever possible – avoid using 100% widths
- 34. Use spacer .gifs for all padding
- 35. Only use CSS for text formatting – font-family, size, color
- 36. Eliminate colspans and rowspans – use nested tables instead to isolate elements
- 37. New versions of Lotus Notes (such as version 8) provide HTML support much more consistent with other email clientsHotmailAvoid the background-image CSS property – use the HTML background attribute instead
- 38. To remove the extra white space that appears below images in Firefox include style=“display: block;” in image tagsGMAIL & YAHOOGmailAvoid embedded CSS. Gmail will strip out embedded CSS, so use inline CSS instead.
- 39. Issues exist with left/right CSS borders, use spacer .gifs or CSS padding instead.
- 40. Avoid the background-image CSS property – use the HTML background attribute instead.
- 41. Gmail Themes overwrite default link colors – always specify desired link colors.
- 42. Don’t forget closing tags. Gmail is very particular about syntax, and the layout will suffer greatly if they are missing.Yahoo!The vertical space between paragraph tags <p> is not displayed – in the ExactTarget editor, use soft returns or line breaks <br> instead. In HTML paste, specify a top and bottom margin of 1em on paragraph tags. (e.g. <p style=”margin: 1em 0 1em 0;”>)DESIGN RESOURCES

Editor's Notes
- #3: 1. Introduce presenters + attendees2. Overview of what we’ll cover.Overview of HTML vs. CSSCode for email not the same as code for webHTML is a markup language that is universally CSS is a style sheet whose form is separated from its contentPut yourself in the customer’s shoes when talking to them – the beautiful, efficient world of building websites with CSS doesn’t apply here.W3C puts together rough standards. These standards don’t exist for email.Proper syntax still counts – opening and closing tags
