Simplify your template
I have noticed that a few of you are completing and populating content into all email elements within your chosen template. Although with some longer newsletter examples this may be required, the majority of email campaigns should keep to the short and simple is best rule.
I therefore recommend reducing your chosen email template, by deleting unwanted email elements. Templates need only consist of 3 elements, a top intro element, a single text article and the footer element. A concise combination of these 3 elements can be equally if not more effective than the longer format.
Why not try the shorter format email with a strong call to action link. You may be surprised by the difference in results.
