I have saved the same invite email twice for the same campaign, but every time I go back to send, it is that default one, not the ones I have made. Where are the ones that I saved?
Re-saving an invitation email will not create a new email message. This simply saves any changes you may have made to the message.
If you would like to create additional emails to send out to your contacts again, what we would call a “Reminder” message, check out the following tutorial which describes this in detail
I hope this helps to answer your question!
