HTML Coding Mistakes
Lots of people try sending their HTML email newsletters with Microsoft Outlook, or Outlook Express. This is a big mistake. For starters, Outlook won't send your email in "multipart-alternative" format. Multipart format means that an HTML email is sent with a plain-text alternative embedded along with it. That way, if someone's email application can't read HTML email, the plain-text version displays instead. Also, Outlook will send all your images along as attachments, which won't always work. Images in HTML email must be hosted on a web server, and your HTML code should point to them with absolute paths. Add to all that the fact that Outlook won't help you track email clicks and opens, manage unsubscribes, or process and clean bouncebacks from your list. Finally, using your desktop email application to send email marketing campaigns is a bad idea because your ISP may suspend your account after a certain amount of bandwidth has been reached (and some ISPs limit outgoing email to 500 per hour).
