How to avoid your emails being labelled as spam
When you are designing a template, make sure that you consider these key factors:
- 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.
- Avoid using too much white space.
