Final answer:
It is not always more efficient to read emails as soon as they arrive; efficiency depends on individual job roles and workflow. Email management strategies are subjective and should be tailored to fit personal productivity and needs.
Step-by-step explanation:
The question of whether it is more efficient to read email as soon as it arrives rather than at set intervals does not have a one-size-fits-all answer. The efficiency of email management depends on the context of the work and the individual's role within their organization. For some, constant email notifications might interrupt workflow and focus, making the "as soon as it arrives" method counterproductive. In contrast, others may need to respond promptly to stay on top of urgent matters.
In terms of email composition, the advice you mentioned about keeping paragraphs short and adding a blank line between them is indeed correct. This makes email easier to read and digest, which could be seen as more efficient from the recipient's perspective. However, the way one manages their own email reading intervals plays more into personal productivity and job requirements rather than the composition of the emails themselves.
