No "login" is needed.
Each flyer you create has a unique "preview/edit bookmark" link that we email to you when you (or your assistant) create a flyer, and in every subsequent email we send you regarding your flyer.
To return to your flyer
click the "preview/edit bookmark" link that was emailed to you. That will sign you in and show you the current status of your flyer.
To see your delivery report
check the delivery report email that is sent to you 4 hours after your flyer is emailed.
However if you discarded that email you can also see your delivery report by
clicking the "preview/edit bookmark" link that was emailed to you.
