Be very suspicious of any link that has a "?" in it. It will almost certainly have more text after that "?" which is data it is sending to the sender's server. You will usually be able to see and read most of that data. But there is not normally a good reason to use that unless you know what the site/company is and why they need the info they are sending. It
can be used to allow the company/site to send you to a different page that will already know who you are or to include a unique code that will give you a discount or other helpful things.
But you should always be given such 'codes' (and even a URL) in plain text in that email, also. Then, use your bookmarks to send your browser to the site and look of the place you can use that code. If the company forces you to use an email link, tell them you don't appreciate that lack of respect for your security and will no longer be doing business with them. And let them know you'll be reporting their lack of customer respect to all your friends. Don't put up with being abused by companies that don't care about your security.
However, when you can read the thing and plainly see a reference to a completely different web site (

NOT IN AN EMAIL?!!!
Just stop clicking on email links. Anywhere. Never do it. Period. Please...
Nor do I believe that simply seeing a
list of emails on an iPhone will do anything.
Viewing the actual message, even a part of it,
WILL download any graphics, visible or not, of course. That will send a message back to the server, just like it does on an email app on any computer. On the iPhone, there is a "Load Remote Images" switch in the "Mail, Contacts, Calendar" settings. That should be turned
OFF. It will not only prevent these messages being sent back but it will increase battery life! Do it. Now!
