Recently I have been transferring four old YG lists to new lists on groups.io
There is one recurring problem, a few members immediately quit the new group when they are welcomed as new members.
Prior to the group transfers, Special notices/messages were sent to inform YG list members of the impending transfer.
However if the member had set YG subscription to No E-mails, they will not receive the Special Notice transfer message and may reject the Welcome letter and unsubscribe from the new list on groups.io
In retrospect this was a major deficiency in the YG lists, and when these lists transferred to groups.io, the problem transferred.
Groups.io has another delivery option, Special Notices Only This is also a no e-mail option, however the member will receive Special Notices (from the Moderators only) when they are issued.
Starting today No E-Mail will no longer be a delivery option, instead it has been changed to Special Notices Only as the no e-mail option.
This was done at the moderator level for all members who had been subscribed to No E-Mail
