Did you know this about email?
Are emails cap sensitive?
When asking for someone’s email address, the chances are they’ve probably said something like “it’s all in lowercase”. But does it really matter?
The answer, surprisingly, is technically yes – but in practicality, almost certainly no.
Okay, lets explain. Other than the @ symbol, an email address has two parts. What comes before the @ symbol (the local mailbox) and what comes after the @ symbol (the domain.)
So, firstname.lastname@example.org – johnsmith is the local mailbox. Hotmail.com is the domain.
Let’s start with the domain. The domain name is NOT case sensitive, and never has been. You can mix and match any case you want, as long as the letters are what they should be, it doesn’t matter.
Things are not so simple for the local mailbox part. Technically the case of the letters could matter because this part is handled by the mail server belonging to whoever is in charge of your email. So for example, Hotmail emails are part of Microsoft and their email servers. Theoretically they could make the local mailbox case sensitive…
…but almost all email providers don’t. Simply to just avoid confusion. In fact we don’t know any email providers that require the local mailbox part of the email address to be case sensitive. Meaning the chances are highly likely that no matter what case you use in any part of the email address, it will simply not matter.
However, to avoid any problems, it is generally considered good practise to type in email addresses in all lower case. Just to be safe.
What does CC and BCC mean?
We see them on most emails we send, but what do they mean and what do they stand for?
Well, CC stands for Carbon Copy. And BCC stands for Blind Carbon Copy.
For those who used it, carbon copies (before the Internet) were those pads of paper that automatically copied what we wrote on the front slips of paper on to the coloured paper slips underneath. Since email addresses on the CC and BCC lines essentially get copies of an email sent to them as well, it was a good as term as any to use!
But what is the difference between CC and BCC? Well, anyone on the CC line gets publicly copied in on the email. And anyone on the BCC line gets secretly copied in on the email, meaning anyone on the TO or CC lines will not know that the email has also been sent to the person on the BCC line.
How much email is spam?
Depending on who you are and how much spam you get, you may be surprised or not surprised at all by the answer to this question.
Over the last decade, over 50% of emails sent everywhere were spam emails. In 2006, most reports suggest spam consisted of between 80-90% of total emails sent. This was down to around 60-70% in 2013 and in 2015 the reports suggest total spam was down to around 50%.
It’s great that spam seems to be less frequent, but it still means literally billions of spam emails are sent every year, and it also means cyber-criminals are looking for newer ways to catch people out – meaning an increase in dangerous malware and social media scams! So beware!
