Tips on how to protect your inbox from spam
All major email providers have spam filters built in to block any spam messages that may come your way. However, they do not always do the job.
Therefore it is helpful to know other ways to guard against such emails, which at best will clutter your inbox, at worst, may contain malware, which can infect your device.
- Do not participate in chain letters. Forwarded or chain emails often visibly list the email addresses of everyone that receives them. This makes people that participate in such activities an easy target to spammers who may use such email lists in their attacks. Be careful when signing petitions, as these may also be used to gather email addresses for attacks.
- Create alias email addresses. Use different email addresses for different services. This way, if you receive spam, you can track it to a specific website that you signed up to. Many services allow you to create multiple email addresses and link them to your core account, which you can keep private.
- Use a complex email address. The more complicated your email address is, the less likely spammers are to guess it. Avoid common words and expressions, which criminals are likely to go after.
- Adjust email privacy settings. Make sure that your inbox spam filter settings are set on the highest level.
- Delete spam emails if you receive them. Finally, if a spam email does reach your main inbox, get rid of it right away. Never click on any links or open any attachments provided in the email as they may contain malware that can infect your device.
