I don't think this is an issue with codeigniter's mailer. Usually, emails are marked as spam by email service providers based on the content or an IP filter. In your case it's possible that your content appear spam-like due to not having relevant text and images. Google and most providers has a list of spam words that they look out for when evaluating the spam-ness of your emails.
