This is dead.
When I haven’t interacted with your site for over X years (take your pick).
Or haven’t received an email to ask if I still want to be receiving these emails.
Or can’t remember why I signed up.
Or was signed up because you had my email.
Your email is redirected right to SPAM.
Your message goes right to the trash.
All your brilliant ideas and well-intentioned thoughts will no longer be listened to because you were hoping for 10% of that mass distribution to respond when you could have received 100% of a response with a focused distribution to 20% of your list.
