Autoresponder sequences

One of the things I've been mulling over a bit today is my autoresponder responder sequence for The AdSense Insider.

I'd like to test the following hypothesis: that people usually sign up for such things on the day of the week that most suits their lifestyles.

For example, for one person it may be that Monday evenings are the best time to browse around whereas for someone else, it could be that Saturday mornings are best.

If this is so, then the implication is that you should create follow up emails that go out on every 7th day so that the Saturday morning subscriber always gets new stuff from you on Saturday mornings whereas the Monday evening browser always gets new stuff from you on Monday evenings.

Always too much to test online but I might do this one day.

I already have info that tells me which day of the week is best for sending out a sales letter!
