Clicked spam link in email

Hi

I was using iPhone 4S, I inadvertently clicked on a spam link in an email (hotmail) sent supposedly from a friend.

I heard iPhones and Mac books are pretty much safe from virus and malware....

Still, I know the risk of clicking on such spam link (which then refers to random link). I don't know why my friend would send such a spam...

I would like to know if my email and my phone is in any way of being compromised.

Thank you.
