+## Criteria for spam
+
+* The sender’s email address doesn’t tally with the trusted organisation’s website address.
+* The email is sent from a completely different address or a free web mail address.
+* The email does not use your proper name, but uses a non-specific greeting like “dear customer”.
+* A sense of urgency; for example the threat that unless you act immediately your account may be closed.
+* A prominent website link. These can be forged or seem very similar to the proper address, but even a single character’s difference means a different website.
+* A request for personal information such as user name, password or bank details.
+* The email contains spelling and grammatical errors.
+* You weren't expecting to get an email from the company that appears to have sent it.
+* The entire text of the email is contained within an image rather than the usual text format.
+* The image contains an embedded hyperlink to a bogus site.
