A trick is to have a unique image, even one dot per address sent. Then
if the image is read, the email was delivered and opened.

Other aspects may involve html /scripts calling home. If you are
especially concerned set your email to use a web proxy for all http. put
127.0.0.1 (or ::1 or whatever the ip6 is if you useit) as the proxy,
assuming your email client runs on a machine with no proxy server.
Then no html content at all works. Of course then remote images don't
work even if you want them.
Don't use webmail unless it has such settings. By and large pop3 clients
such as Thunderbird are safer.
