It's so good to see someone bulk at the Seven Rule. I've never bought into this based on my marketing experiences outside working virtually. The touch contacts can be more or less, in my experiences, based on the solution the end customer is seeking.
I cringed when a colleague said she worked up a system to get all '7' of her touch contacts in within a 7 day period so by week two she felt she'd primed her new contacts to be ready to say 'yes' on the next email. There's little surprise her conversion rate was still low and her unsubsribe rate was modestly high.
