Did you get a answer for the question I asked you about ? Several days back.
Is "Did you get an answer for the question I asked you about? Several days ago" the content of the email you are planning to send? If so, it is incorrect. I would send, in a follow-up email, something like:
Hi. I emailed you a few days ago about [subject]. I wonder if you have a response/any information for me yet. Thanks.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
