How can I contact Instagram?

[Emily]

I need to contact Instagram about a general inquiry - it's not a problem with the app and it's not something that is answered in the help section. It's about the suggested users...long story. Anyways, it's just a general question. However, I cannot for the life of me find a contact email address for Instagram! When I search on Google "Instagram contact email" I see a link that takes me to this page: http://help.instagram.com/customer/portal/emails/new
however when I click on the link it tells me the page cannot be found. When I send an email to support@Instagram.com it bounces back and tells me they no longer support that email address.
Does anyone know Instagram's contact email address for general or even marketing/sponsor inquiries?
