The sign-up form for "The Yodel" and other Yahoo newsletters [1] [2] allow any email address to be signed up, but newsletters do not appear to be delivered to non-Yahoo addresses even if they are connected to a Yahoo account.

I have tried to sign up using the external email address connected to my Yahoo account, as well as an alternate email address hosted by AOL, but none of the newsletters has been received even after disabling spam filters. Normal account communications have been received without issue.

It would benefit both Yahoo and its users if "The Yodel" and other Yahoo newsletters could be distributed to anyone who wants them even if they don't have a Yahoo Mail inbox.
