I’ve just purchase few items from Photodune and GraphicRiver. Purchase confirmation emails arrived in my inbox regulary. Photodune purchase confirmation email (from Outlook Express) I see a code without any images, and from GraphicRiver (Yahoo webmail) confirmation email is empty! Also as an Author I think this Bug can decrease our sales (part of email marketing). I will flag this for staff reply and sending ticket to support.
Update: Ticket ID: #VWG-416-32032
Hey, Misel. Similar problems here: http://audiojungle.net/forums/thread/approvalrejection-emails-formatting-broken/82089
It seems like Envato has some e-mail problems. But hopefully our tickets will be helpful to them.
