You always have to type "
https://www.paypal.com]
https://www.paypal.com[/url]" in the address bar of your browser.
You can verify that you are on Paypal website just looking on the address bar. It should look something like this in the below pictures.
There is a green area on the left part of the address bar. If you click on it, it will tell you that you are on Paypal.
I receive from time to time phishing emails. They usually tell that there is a problem with your account and you need to log in and type some information. If you don't do this, your account will be suspended.
Always check where a link is going before you click. Move your mouse over the URL in the email and look at the URL in the browser . If it looks suspicious, don't click it. Open a new browser window, and type
https://www.paypal.com]
https://www.paypal.com[/url]
