Start an email with a central focus and a catchy headline
This is the area a reader first sees and reads. It's usually tied into the subject line of the email. Depending on the goal of the email, the amount of copy can vary. The same goes for an accompanying image.|
Additional articles can then appear below the focus area. They don't need to be related to it.
The overall rule of thumb is to make content easy to digest by breaking it up into pieces.
This allows the reader to scan through it. There are often articles linked for further reading.
