As with all email lists, (a) is typically a fairly stable function of:

- list age (which we know) - list quality (it's opt-in and highly specialised, so likely very high; certainly comparable to e.g. EAMT, Moses lists) - list member count (the unknown)

(b), and its counterpart (b1) - open the mail, vary depending on the subject line and time of day.

(c) is often only really useful to measure per-email, because the factors that govern what one does with an email depend on that particular email; the action rate of a list when there are multiple senders on diverse subtopics is not too useful to know.
