I thought the original data was out of date and list churn wasn’t that 
extensive. Turns out, I was wrong.

Speaking for myself, if I were managing such mailings, anything longer than 3 
months and I'd wanna toss it and start over.
Or at the very least, send it out from a dedicated IP pool different from the 
ones used by the main lists.

Aloha,
Michael.

Is there a BCP or consensus on how long a list can sit inactive before it 
should be thrown away?

For political/non-profits, I tell my clients that about 1/3 of the list
goes bad each year. The math usually works out when they send after not
listening.

I don't think there's anything particularly solid.

If you're not mailing to a list at least monthly you need to really be aware
of address churn.

But if you're, say, a political organization it's not impossible that your 
expected
tempo for some segments might have gaps of maybe three years in it. Sending
*something* more often is a good idea, but I'd be more likely to tell you 
"expect
some serious delivery pain when mailing this" than "you have to throw it all
away".

"Best practice for spamtraps is that the reject mail for 12 months before being
reused" would be part of the "expect pain" conversation.

Cheers,
  Steve
