Email was invented in 1971 and became popular during the late 90's. We've been using it seriously for 20+ years. Some of you reading this will remember how amazing it was when we all started using it. Remember your first email address? Mine was with Yahoo! Millennials will snigger at this, I know they will, some haven't even got an email address!
And although we've had enormous change with email, most of us are still basically using it for the same purpose. To send messages, share files, photos and opinions.
And of course with all new inventions email soon became a method for spammers to hack servers and send us all emails promoting goods and services we weren't looking for. (SPAM)
And then there is the ’Email Newsletter’. If by chance you shared your email address on a website or purchased some goods online your email address could be added to a list. The owner of the list could then keep you informed of their news, which often included promoting their goods and services too. You may have even wanted those newsletters, but now they are a pest!
Over time newsletter clients, like Constant Contact, Mailchimp and others started to emerge and provided some rules around uploading email addresses. One of those rules would be obtaining authorisation from the email owner before adding them to a list. However as long as you tick the box that confirms you have authorisation, they allow you to upload your list. And then you can legitimately email (SPAM) your contacts.
Let’s not forget Data Protection in Europe. The Data Protection Directive (officially Directive 95/46/EC on the protection of individuals with regard to the processing of personal data and on the free movement of such data) is a European Union directive and was adopted in 1995. It regulates the processing of personal data within the European Union. In essence it means when you hold personal data, like an email address, you must have obtained it with the owners permission and provide any recipient of your email newsletter the opportunity to unsubscribe.
Nowadays the best process for obtaining authorisation for using someone’s email address is using a double opt-in process. That means the email owner has to confirm authorisation and knows without a doubt that they are being added to an email list. This is by far the best process in my view. BUT many don’t bother with this process.
With the creation of LinkedIn, it means that your connections have access to your email address. They can download your email address to add to their email list whether they have your authorisation or not and then start to email you their newsletters (SPAM).
I've been unsubscribing from newsletters for over 4 years and receive very few unsolicited emails these days. However I still receive around 4-6 newsletters I never signed up for per month. Plus the instances of poor practices in those emails, where you are unable to unsubscribe seems to occur more often. I send those senders a polite email to ask how I got added and ask to be unsubscribed. Below is the text of a recent (March 2016) email I sent to the sender of an unsolicited email I received.
