Best practice guidelines for internal and external mailshots intro
Email is used as the University's primary communication channel with both staff and students, also with external contacts such as prospective students, academic partners or industrial contacts.
Occasionally, mailshots are sent to individuals, groups of individuals, mailing lists or distribution groups (all of which are slightly different things) but they end up in the Junk Email folder. This can be for many different reasons, but it's important to understand that spam/Junk filters are machines. They cannot see context and they don't generally understand nuance - if they've been told by lots of people in the past that a specific type of message is spam, then they'll process it as such.
Remember also that once you've sent your message and it's got through the filters on that occasion, the next one might not - the filters are dynamic and take feedback from users (marking messages as Junk) alongside many other data feeds.
Here are some guidelines that should reduce the risk of your message going in the Junk folder:
You know what you have to say, and most likely to whom you need to send it - so don't send thousands of messages to people when a couple of hundred will do. The more recipients decide to mark your messages as Junk, the more likely it is that all your emails will end up in the Junk in future.
This is a classic hallmark of spam, used for 20+ years to mask the recipient list. If you must Bcc someone, save that for personal communications. If you need to send the same message to lots of internal recipients, use the appropriate distribution group or mailing list.
It's known as 'shouting', it's perceived as rather rude, and the machines think it looks like Junk. The same applies to the message body - if there's a lot of sentences in capitals, your email is at risk of being classed as Junk.
Spam often contains very long runs of hidden, unrelated text in an attempt to bamboozle the AI/Machine Learning technologies that are used in automated filters. As a result, some filters will rank a message more highly if it contains lots of seemingly unconnected text. Additionally, sending a one-word email to hundreds of people could trigger a Junk classification.
Again, this is an old-time spam tactic. If you need to send out large numbers of links, consider putting them on a web page on your department's site or on a module or programme page on Learn, and send a link to that. It's also much easier to re-use the content if you've put it somewhere on the web.
In Loughborough's system, these are in the Outlook Address Book with names beginning "Dept." or "School." or detailed on the mailing lists page which can be found on the IT Services website. Each one of these is a single recipient with many members, so your message is viewed as a single message to each group/list rather than being tens-to-thousands of separate messages.
This applies to text within a message, or repeatedly sending the same thing to the same recipients over and over again.
