No, not from people - or sources - I know, respect, or are vouched for.
I work remotely, and often work abroad; emails are my lifeblood, professionally and personally, especially when other forms of communication are challenging or difficult.
However, emails need to come from a verified, trusted, or known source.
You are confusing the means of communication (email, which is not the issue) with who is communicating (someone unknown, and therefore neither trusted nor verified), and what the communication addresses.
You are also confusing the means of communication with how the communication takes place.
Email is not the issue: Rather, the fact that it is an unsolicited, unsought, unverified communication is the issue.
Others have already remarked on how it is far easier if communication is initiated by the person seeking this information, rather than by the person who wishes to spread information in the absence of a formal - and verified - support system (such as university, government, health authorities).
Otherwise, in the absence of a credible authority, body, (or person) to corroborate what you say, write, peddle, promote, I have to assume an agenda; you want my time, or my money, or my attention, or you want to peddle some agenda or conspiracy theory - and, frankly, I have neither the time nor the interest in such.
