I run 2 lists.

The oldest list (2005?) is on Yahoo, the newer one on google.

I have a template email with the Yahoo group as the To address & add new members in the BCC field. I was having a lot of trouble adding new addresses several years ago, so I gave up & now have 60 bcc addresses. Maybe it is easier today ...

We have been planning to move the list to mailchimp, but I'm glad nothing has happened so far.

The Google list is much easier to manage as I can Directly Add members.
