I've experienced the exact same situation discussed in this thread, and I find it quite annoying.

I was not surprised to receive an error message when I clicked the link that says, "If you think this email was sent in error or you'd like to change how you receive your notifications, click here," as I believe it is blocked by Verizon when accessed from outside the U.S.

@vzw_customer_support
, I tried to send you a private message, but it seems that option is unavailable (it redirects to search the community instead of composing a new message). That's why I'm posting a new thread here, and I would appreciate your assistance regarding this matter
