Sadly, email is not an entirely reliable communications medium, thanks to spam filters, addressing errors, and server failures. With certain types of email, it’s worth double-checking that a message was seen. One example of that we see is with reports of phishing email, which miscreants use to try to trick you into revealing passwords, credit card info, or other sensitive information. Phishing messages can be tricky to identify—that’s their goal. If you’re forwarding a possible phishing email to us or another trusted technical contact for evaluation, remember that spam filters often catch such messages, so they may go unseen. To work around this awkwardness, send a separate message saying you’ve forwarded what you think might be a phishing message so the recipient knows to check their Junk mailbox if need be. It’s helpful if you can include the Subject line of the suspect message.
