Why some marketers are shifting their focus from inboxes to mailboxes

Because the early edges that some early digital marketers were able to exploit have been competed away, “old school” method are making a come back (direct mail)

I am convinced that brands will partner with these newsletter creators for the simple reason that with audiences increasingly shifting to dark social channels (newsletters/inboxes, chats, etc.), brands will have no choice but to change their approach and allocate budgets from content and advertising.

This is why writers like newsletters so much. **As other distribution channels are becoming increasingly crowded, email provides an alternative trade route.**
