Queries to Investor relations

Hi,

I want to understand are there any guidelines/rules regarding writing to investor relations of a company. Say, i want to reach out to a micro cap that doesn’t do analyst concalls or IPs. And i want to ask questions regarding business in capacity of an individual investor.

Is the company obliged to reply to me?

Won’t this create information asymmetry in the market if they do reply since some investors will have more information than others?

Thanks
