I can vouch for that, Bazyle, as one who won't be inundated either. Nor visiting despite ten-minute walks to my nearest.
Both my geology club and model-engineering society send out frequent e-post flyers.
The former is mainly links to various published articles of geological matters. We'd arranged a small-group. local field-trip for November – then that had to be cancelled.

The MES' round-robins fall into two camps. One camp is admin notices from the Committee including the booking-system for access to the club site (very few allowed at a time, with their names published a day or so beforehand). The other is members' posts of work-in-progress, garden-scale railway operations and in the last couple of day, several Christmas Greetings messages to one and all.
The fly in the tapping-paste is that it appears some combinations of computer, software and ISP won't allow responses or your own contributions to wholesale round-robins. Mine won't. Oh well, that's computers for you.
However, your point is a very good one.
