Most mailing lists that I know of produce one copy of the outgoing
mail with a large number of rcpt-to's, so it's not very important
to them. Where it might be useful is for, say, an outbound marketing
campaign where you send the spam^H^H^H^Hmessage to each recepient
individually.
It is quite common for bulk mailing services to re-use the same body
for multiple postings.
It provides a basic level of per-user tailoring that is quite useful.
Isn't that what I just said?
No. You said it might be. I said it was. The difference is particularly
significant with respect to:
In any case, I wonder how useful it really is because lots of bulk
mailers try to customize their message to the recipient. This seems
like a pretty marginal optimization to me.
because this observation is the usual comment at this stage of a discussion
about this topic, and the question is left at whether same-body/different-header
messages are actually sent. I am saying that they are.
This does not say that tailored bodies are not also popular. Merely that they
are not the only model that is used.
