Don't click on links in emails regarding your accounts.

While the majority of emails you receive regarding your various online accounts are legitimate, a few are not.  These illegitimate emails are most often attempting a scam called "phishing."  By appearing as the service provider you use they often ask you to click a link to log in to your account and take some action.  If you take the time to look at the link you'll notice that the primary domain name (www.primarydomainname.com) is not what you should expect (i.e. www.yourbank.com).  Any information you input on these fake websites can be recorded, including your login credentials.

The safest way to check on your accounts?  Go directly to the website where your account is by  typing in their address and login there.  Make sure there is an HTTPS in the address bar - the "S" stands for secure (encrypted).

If a legitimate online service provider requires action on your account, they will notify you on their site when you are logged in.  If you ever aren't sure, call or email them directly with your question.
