I'd imagen a email that generic to esa would get a lot of emails. I assumed you were directing the email at a specific department. I'd imagen they clicked on the link at the bottom and got the security warning and left it at that.
It is very easy to contact ESA:

Alternatively, if your request is about education, you can write to: education @ esa.int

media @ esa.intFor employment opportunities or training at ESA, write to: contact.human.resources @ esa.int

For enquiries with regard to images, write to: spaceinimages @ esa.int
For enquiries with regard to video distribution, write to: spaceinvideos @ esa.int
So I sent a polite e-mail twice to
media @ esa.int and you assume they klicked on the link, etc. Sorry, according my cookies, etc, ESA never clicked on it.
Security warning! Plenty, >500 people klick daily on the link to my friendly web site and do not receive any security warnings. Are you sick? Do you belong to the ESA gravity assist sect? Then you need medical or psychic assistance.
I assume ESA cannot reply and therefore just ignore to reply. The simple solution.
I will send the email to ESA again week 1, 2015. Maybe they are all on vaccation?
