I don't care about email. But what you are suggesting is a different thing and is self-defeating. GBomb archives the template with the ssi tag inside, not with the output in the moment of the scheduled archiving.

So, in Feb 2015, you'll have a "daily archive" with 3650 pages, any of them publishing a random selection from the same group of news dated Feb 2015. And it isn't in anyway the purpose of an archive (and even a very "search engine stupid" thing).

Can i conclude it is impossible to archive the feed mix?

Bye.
