I found this intriguing tidbit on BBC News (here):
“A Norwegian computer expert has created a website enabling anyone to send an email about the war in Ukraine to up to 150 Russian email addresses at a time, so that Russian people have a chance to hear the truth their government is hiding. All over Russia email inboxes are pinging. Millions of messages are being received with the same intriguing subject Ya vam ne vrag – I am not your enemy.
“The message appears in Russian with an English translation and it begins: ‘Dear friend, I am writing to you to express my concern for the secure future of our children on this planet. Most of the world has condemned Putin’s invasion of Ukraine.’ The lengthy email goes on to implore Russian people to reject the war in Ukraine and seek the truth about the invasion from non-state news services. In just a few days, more than 22 million of these emails landed in Russian inboxes, and they’re being sent by volunteers around the world, who are donating their time and email addresses to the cause.”
I’m not sure this is his website, but there are instructions here.
