When I sent HTML e-mails using cfmail, some of the recipients say they can see anything. Why is that?
HTML formatted e-mails should contain a plain text e-mail and an HTML formatted e-mail together. E-mail clients that can display the HTML version will; those that can’t will simple display the plain text e-mail. ColdFusion HTML e-mails don’t have two parts – they only contain the HTML e-mail. Using the CF_HtmlMail custom tag, you can send an email that contains an HTML formatted message AND a plain text message. If the browser knows what to do with the HTML tags, it will display the HTML message. If it doesn’t, it will display the plain text message – the email client chooses automatically.
