This article takes a quick look at
the harm introduced by multi-generation forwarding.
- The percentage indicates the % of recipients who in-turn forward
- The columns represent the average number of recipients in
forward mailing list.
- The rows represent the recipients of each generation

- If 10% forward to 15 others, the 9th generation alone reaches
1,123, with a cumulative total reach of 3,081 people.
- If 20% forward to 30 others, after 9 generations, the message reaches/bothers over
72 million people! And, if BCC wasn't used by everyone at every
level, the email addresses are potentially exposed to the same 72

- If you must, be extremely selective with your forwarding
- Periodically re-evaluate and prune your list.
- Formally make it an opt-in list, or at least actively
- Always use BCC.
To/CC are reserved for small groups of closely related
