Spam is both an annoyance and a risk. Dealing with unwanted messages wastes our time – and some of those emails are downright dangerous. Which is why all email services now offer anti-spam tools to detect and filter suspicious messages.

But what happens when an important email is incorrectly flagged as spam? How can you stop it happening again? This is what you need to know:

  • Log into your account at then click Clog icon in the top right corner of the menu.
  • Click See all settings -> Filters and blocked senders
  • Select the Create filter option
  • Enter the sender’s email address and click Create filter
  • Select the Never send to spam checkbox and click Create filter again to finish.

You can repeat this process for all of your important contacts.

  • Open the incorrectly filed email and click Junk from the top menu
  • Click Never block sender from the menu that appears.

Alternatively, click Home -> Junk -> Junk E-mail options. Click the Safe Senders tab to access a list of ‘trusted’ addresses which will never be sent to spam. You can add other addresses manually if required.

With Outlook you also have option to Never block sender’s domain which is very useful if you have problems receiving emails from a specific company or website. spam settings, Microsoft’s webmail service, works in a similar way to the Outlook application. To ensure mail delivery: 

  • Log into your account and click the Cog icon in the top right corner of the screen.
  • Click Email -> Junk email -> Add
  • Type in the address you want to trust
  • Click OK

If you use Outlook and, your safe sender settings will be synchronized automatically so you don’t have to repeat these steps.

  • Type a Description in the box
  • From the dropdown menus below, select From (1st box), Contains (2nd box) and type the safe email address in the third box
