To reduce the amount of spam emails, there are several actions you can take:
Check your email security settings to ensure only authorised people can email you.
Create a strong and unique password that cannot be easily guessed.
Create a secondary email address or alias that you use when registering on websites or shopping online.
Sign up to the Telephone Preference Service – free service allowing you to opt out of receiving unsolicited sales and marketing calls.
Install an anti-spam software such as SpamAssassin that scans your emails and filters out any spam emails.
Keep your web browsers and operating system up to date.
