Chase periodically tells me that an email has been rejected and asks me to confirm that the address is still valid. I do not care about the statement notices, because I have all of my account closing dates in a calendar. Have you tried creating a new email address to see if it solves the problem?
I have five active accounts with Chase. Four accounts I receive the notice A, B, C, D. I didn’t receive a notice for account E. All the accounts have the same email address. Then I receive a notice the following month for Accounts E, B, C and D. I receive a letter about Account A having the wrong email address.
I nearly missed a couple of payments because I didn’t know the statement were available. I do receive notices to the correct email address that the payments are due in ten days on all the accounts. I started checking online about three or four times a month. I have canceled the paperless billing. I have all my other banking and brokerage accounts using the same email address without any problems.
