The in-app upgrade for MailShot has now been renamed to “MailShot Upgrade” on the App Store.
This is to avoid confusion, as a few users were downloading the full-price “MailShot Pro” app believing they had already bought it, when they had in-fact upgraded “MailShot” in-app. As the App Store regards those two items as different things, this would result in them being charged twice.
With the in-app upgrade, “MailShot” still has all the same great functionality of “MailShot Pro”.

This email app worked great for me right from the start. Solved the multiple email dilemma big time. I can’t, however, find the method for sending multiple photos. What am I missing?
Hi Jimmy
Thanks for your comments, we cover two methods on our support page here
https://solubleapps.com/mailshot-support/#PHOTOS simply attaching images using the “Photos” app.
Or for a more artistic approach on iPad, for example, you could create a journal in “iPhoto” then share the link to a MailShot group.
