The DMA Email Marketing Blog has an interesting post up redefining "inactives" as "emotionally unsubscribed." They cite several instances where a significant number inactive list members have been triggered to take action based on their personal 'itch cycle.'
In one case, over $115,000 dollars was generated by making a special offer (a really great offer) to those list members who'd not click on the previous 25-40 past offers. Another statistic showed that over 10% of the revenue generated in 2008 had been contributed to the bottom line by list members who had not opened or clicked a single message in the previous year.
The lesson is to not over-obsess about inactive members on your list. Just because not everyone feels compelled to read every single missive you send, doesn't mean they won't remember you when their needs match your offers.
