It’s often difficult to distinguish a fake email from a verified one, however most have subtle hints of their scammy nature.Here are seven ways to help you recognize a phishing email and maintain email security.
1. Legit companies don’t request your sensitive information via emailChances are if you receive an unsolicited email from an institution that provides a link or attachment and asks you to provide sensitive information, it’s a scam. Most companies will not send you an email asking for passwords, credit card information, credit scores, or tax numbers, nor will they send you a link from which you need to login.

2. Legit companies call you by your namePhishing emails typically use generic salutations such as “Dear valued member,” “Dear account holder,” or “Dear customer.” If a company you deal with required information about your account, the email would call you by name and probably direct you to contact them via phone.

3. Legit companies have domain emailsDon’t just check the name of the person sending you the email. Check their email address by hovering your mouse over the ‘from’ address. Make sure no alterations (like additional numbers or letters) have been made. Check out the difference between these two email addresses as an example of altered emails: email@example.com firstname.lastname@example.org Just remember, this isn’t a foolproof method. Sometimes companies make use of unique or varied domains to send emails, and some smaller companies use third party email providers.

4. Legit companies know how to spellPossibly the easiest way to recognize a scammy email is bad grammar. An email from a legitimate organization should be well written. Little known fact – there’s actually a purpose behind bad syntax. Hackers generally aren’t stupid. They prey on the uneducated because they are easier targets.
|Notice the apostrophe in the word 'friends'? Me neither. Other than that tiny grammar mistake, this is a very convincing email.|
5. Legit companies don’t force you to their websiteSometimes phishing emails are coded entirely as a hyperlink. Therefore, clicking accidentally or deliberately anywhere in the email will open a fake web page, or download spam onto your computer.
|This whole email is likely a gigantic hyperlink.|
6. Legit companies don’t send unsolicited attachmentsUnsolicited emails that contain attachments reek of hackers. Typically, authentic institutions don’t randomly send you emails with attachments, but instead direct you to download documents or files on their own website.
Like the tips above, this method isn’t foolproof. Sometimes companies that already have your email will send you information, such as a white paper, that may require a download. In that case, be on the lookout for high-risk attachment file types include .exe, .scr, and .zip. (When in doubt, contact the company directly using contact information obtained from their actual website.)
|Just remember, curiosity killed the cat.|
7. Legit company links match legitimate URLsJust because a link says it’s going to send you to one place, doesn’t mean it’s going to. Double check URLs. If the link in the text isn't identical to the URL displayed as the cursor hovers over the link, that's a sure sign you will be taken to a site you don’t want to visit. If a hyperlink’s URL doesn’t seem correct, or doesn’t match the context of the email, don’t trust it. Ensure additional security by hovering your mouse over embedded links (without clicking!) and ensure the link begins with https://.
