In brief, I want to write an e-mail inquiring an agency as when will they submit the work. This is what I have written. I am not quiet sure whether it is the proper way of writing the mail. I would appreciate if you could provide feedback as to how can I write it in correct grammar.
Hope you had a great weekend. I wish to inquire as when will you submit the files regarding the project.
Many thanks, Oklao Sds
Is it grammatically acceptable?
