How Does Gmail Determine an Email Is Spam?

Gmail’s junk mail algorithms are quite effective at filtering out unsolicited and unwanted junk email, automatically delivering it to recipients’ spam folders. Unfortunately, there are times when legitimate emails are marked as spam, even though the subscriber wanted to receive them. Although email services such as Gmail don’t share the exact algorithms for deciding if an email is unwanted by intended recipients, the following are some the major reasons why an email may be marked as spam:
  • Content — Typically one of the least common causes for pushing an email to the junk box, certain words or phrases found within messages can cause them to be filtered.
  • Links — If a message includes links to websites that are blacklisted, they could result in the message being filtered as spam.
  • Source — If other email messages sent from the same Internet Protocol (IP) address that you use appear to be spam, your emails may be categorized that way, too. In other words, it’s guilt by association. This can become a problem for small email senders who are on shared servers.
  • Headers — If there are inconsistencies in the “from” and “reply to” addresses and domains, emails will be filtered as spam.
  • Engagement — Recipients can deliberately mark certain messages as spam, but engagement metrics, such as open and click-through rates, also can affect the email-filtering process. An increasing number of Internet service providers (ISPs), including Yahoo! and Gmail, are using such engagement metrics to determine if an email should automatically be blocked or filtered as spam. In effect, Google is simply trying to provide a great user experience, just as Google’s search algorithms do. So, Google views engagement metrics as an indicator of whether or not the user is interested in emails from that sender. We have seen tests where lists with high levels of engagement get through Gmail’s junk filters, while lists that without the engagement don’t get through.
Last point make sure you have a SPF record from the ip/domain where it leaves, also A PTR record for the broadband your using as sometimes we do reverse look ups.


Hope this helps

Bugs in your Keyboard

A client walked into our workshop a few days ago, and mentioned is laptop had viruses, we took it in as normal. - Newport 

While we had it on the bench we started with booting it up and scanning for viruses, this usually takes a few hours, engineers would pop in at random intervals during the day to check on its progress.

Four hours passed and one of the team engineers cried out "OMG look at this".


Take a closer look at the keys and the white specs "oh they are all moving"..

A: While a bug infestation is unusual, laptop keyboards can get crudded up (that's a technical term) with food bits, liquids, and other detritus. And unlike a desktop keyboard, a laptop keyboard is tough to throw away. Honestly, the best thing to do is to give it a super hoover.

Take the keyboard off, hoover all vents, hoover the keyboard too.. Place the keyboard into a bag and place a moth ball also, seal the bag leave for 24 hours..

Brush all under the keys using a small paint brush, hoover again to get everything reassemble.

All should be well again.. I know our client was..

Fitness Centre

We have a local site that used pods (these are computers in large game type units with a touch screen)

The idea is public come in using their fitness keys which monitor their performance as and when the use the equipment.

The pod displays the data how they are performing and what they need to do.





These Pods costs approx £3000 each and are approx 5' high x 3' wide x 3' deep (feet).

A2Z computing had to design and build a equivalent pod which did everything and up to date for approx less then £1000 and only 3"deep x 16" wide x 11" high. (inches)




 Here we can give you a breakdown what it looks like :

(assume there is a 14" Touch screen in place of the paper)


Here it is with a working screen in bits:

this is when we have just fitted ours the the wall:

ours again now with trunking and power with software installed:
