be aware that anything that wants you to click a link could be dodgy, also anything with a zip file attached that your encouraged to open is likely a scam unless you know the person it came from. Also beware that there are ways to make it look like an email came from someone else like big companies or government departments. if you place you mouse over the link and look at the bottom of your screen the real address should come up. read it very carefully, often scammers come up with addresses that look like the genuine one but aren't.
