I registered yesterday with Constant Contact and today my account is inactive. I was told to contact Customer Support but this seems impossible without logging in. I tried to login with my Paypal account but still, it did not work. I thought this would be much of a guarantee!!
I am Italian, live in Austria, travel for work, currently in China where I simply cannot work if I do not use a VPN. I guess that's why I was thrown off the system.
If at least you had a possibility of chat or email without logging in, I could explain!
I understand safety and security but there must be a way through for honest people who are already bothered by having to use VPNs in their most simple work :(
I am not expecting an answer, just hope this is useful to you.
As for myself, I am going to register to Mail Chimp or anything else similar that does not throw me off that easy.
