Solicited sales email distribution - advice needed

Allegedly, on or about 20 May 2013, Gary Stainburn sent:

There's any number of cost-free services that can do things just like
that, such as yahoo's mailing lists (yahoogroups).  I'm not sure how
they, in particular, handle an administrator adding mail addresses to
the distribution list (as doing that too-simply would allow spammers to
thrive), but it certainly allows individuals to subscribe and
unsubscribe.

One place to ask would be their ISP, presuming that's not you, they
might offer a solution.

All mail to my mailbox is automatically deleted, there is no point
trying to privately email me, I will only read messages posted to the
public lists.
