Is there an absolute number of emails or posts that is "Just Right?" No. As I tell my content planning clients, the best outreach volume is the one
you can maintain consistently
that doesn't let people forget about you or that they signed up for your list
that gives you room for added outreach wildcards like launches or tie ins
that doesn't annoy and come off as bombardment
that supports building trust and building the conversation with the people you're reaching out to
