I had to get my next post out before you responded, so I played with the delivery number/times and was able to get all 93 of my subscribers sent the new post e-mail, thank goodness.
And as far as the 2nd part of my question, is there a way to send those subscribers that did not get my new post alert e-mails the alert e-mails at a later date? At least one of my new post alerts that was not sent to all of my subscribers was a key post and one of the main reasons I started my blog to begin with, to warn other dog owners how a commonly prescribed vet medication killed my dog. I would like to make sure everyone on my subscriber list at the time got it. Is that possible?
