Sorry for my late reply as I had many emails to go through. The new orders for the outlet handbagand jewelery of Season Fall 12 were received last week. The bulk SOs is being created so I have to work very late. Moreover, every time these orders are received, I need to work overtime until 8pm/8:30pm. Could you please suggest some methods for improvement ? Hope you can kindly understand this heavy workload.

had: you had many emails (past tense), since you have gone through the emails, you no longer have many emails
through: spelling
the outlet: need article before noun
is being created: tense of verb
every time needed: need pronoun
methods: some = plural, noun needs to be plural
to improve? : questions usually do not end with verbs
workload: more specific on what type of workload (heavy)
