Is there any mailing list or mailing software that could handle this kind scenario:
If I join to mailing list at week 4, mailing system starts sending me emails starting from number 1. Next week, on week 5 my friend joins to mailing list too, and the mailing system starts sending emails to him, starting from number 1 too. If another people joins to mailing list on week 5 too, he also starts receiving mails starting from number 1. And this continues weekly until everyone on this list has received all, let's say, 35 emails.
