John: Ah, so you want them to be stored somewhere in an archive that others can search. I understand. So you need a solution outside your email account and local apps. I guess there are some blog platforms that allow you to send an email to them and they end up as a blog post, searchable on the site. You can do it with your own WordPress website as well. So you can sign up for it and then include that email address when sending, and the message ends up as a post on the site.
