You should not be specifically contacting someone because they put your question on hold. There's already a required close reason stating why the question is not a good fit for the site, and moderators tend to leave comments on posts that they close.
Before you do anything, please check your site's on-topic and off-topic guides. There are often cases where you think your question is on-topic for a site, but it's actually not.
If there's any way you can improve your question by editing, please do so. Edits made within 5 days of closure send a post to review where privileged users can review it and decide if it should be reopened or not.
Additionally, you can ask on the site's per-site meta if you believe your question was wrongly closed. This allows you to receive more feedback and exposes it to more users across the site.
