How to avoid your emails being labelled as spam

When you are designing a template, make sure that you consider these key factors:

  1. Ratio of images vs text - make sure it is more of a 30% image / 70% text split i.e. if you have an image heavy signature and send a short message, this may be blocked.
  2. Avoid using too much white space.
  3. Don't use too many capital letters in the template.
  4. Make sure there are not too many special characters e.g. * _ - “
  5. Never use too many keywords e.g. Free, Cheap etc….

  • Body of message incorporates a tracking ID number.
