Great workaround in IOS9
I was very worried when I heard that the app no longer could select a group mail program as I send out a group of about 80 emails.
The two ways to work around the IOS9 change are excellent. If I am composing an email to a group, I do it in MailShot, if I am forwarding an email, I copy the group list from mailshot onto the clipboard and and paste it into the blind carbon copy line in mail. A little extra work but hopefully Apple will shape up and allow the app to work as previously.
