How to avoid having your email to the list be ignored as spam
A common problem is individual email accounts being hacked, and spam and/or links to viruses being sent to every contact in the address book.
This includes your mailing list.
Typically, the hacker sends a message to dozens of email addresses in the address book, in either the To: or CC: line.
Our system assumes any email with more than 2 addresses in the To: or CC: fields is a piece of spam, sent from a hacked account
And the message silently disappears.
Just send your message to the mailing list first.
Then, send the message again to whoever else you choose.
