Back in the late 90s, the recommendation for migrating from one list platform to another, was to send an email with the new subscription address for the list, to list-members, advising them that they had to go through the subscription process, and list management would not help them subscribe. A 30% loss of subscribers was about par.as group owners we are like Chichikov in Gogol's "Dead Souls"-- continuingThat makes me wonder (going off-topic here) if there could or should be a feature wherein we can ask members to actively confirm that they want to stay in the group.
Based on that advice, some list-owners sent a notice to the list every 6 to 9 months, announcing that everybody would be removed from the list, and would have to resubscribe, if they wished to continue receiving messages. More than once I subscribed to such a list, only to removed the following week, and having to resubscribe to it. Typically, such purges resulted in a loss of between 20% and 50% of the subscriber base.
In the early noughts, more than one book on mailing list management suggested a rule of unsubscribing an individual, if they had not made a post within the last 91 days. List-owners that implemented that rule discovered subscriber numbers took a nosedive, and stayed down.
List-owners for free groups may have to resort to tactics similar to those described, to stay under the maximum member mark.
On the upside, Mark did give a month's notice, for list-owners to skate in under a grandfather clause.
