If I send a campaign, I usually end up with a number of unopened emails, for which I can send a Chain campaign.

However, if some new contacts arrive in that mailing list following the initial campaign mail-out, they are not added to the Chain campaign.

I think they should be added, otherwise they miss out on the campaign! (They make have added themselves to the website without knowing about the campaign, or a fellow sales rep my want to add his contacts to the existing campaign).

Can you please fix this?
