It would be useful to resend an email to those who have not opened it without resending it to the entire segment or database. Organizations and donors/volunteers would benefit from smarter communication, and the elimination of unnecessary emails to those who have already opened or responded.. MailChimp has the option to resend an email to non-openers. You simply have to click a button to resend the email to the segment that did not open the original one. A resend button could be added under the mass email reports section.
