I apologize you're unable to view your invoices as easily as you should! What exactly happens when you do try to view them (blank pages, error message, etc.)? What time frame are you selecting? I have taken a look at your account and was unable to replicate the same experience. Your invoices did appear for me in your account. Because of this I would suggest also trying in a different browser or a private/incognito window. We have seen cases where 3rd party add-ons that could affect how Constant Contact works in a browser. You also have the option of contacting our Billing Support directly. One of these agents can help share a copy of any needed invoices.
