Enabling two-factor authentication adds an extra layer of security to your account. With two-factor authentication, you will need to enter a code sent to your phone or another device in addition to your password when logging into your email account.

Be Cautious When Opening Email Attachments

Email attachments can contain viruses or malware that can infect your computer if opened. Always be cautious when opening email attachments, especially if they are from unknown senders or contain suspicious content.

If you receive an attachment from someone you don’t know, don’t open it unless you were expecting it. If the attachment is from someone you do know but seems suspicious, contact them before opening it.

Adjust Your Email Privacy Settings

Adjusting your email privacy settings can help limit the amount of personal data that is shared and prevent targeted ads. Most email providers allow users to adjust their privacy settings by going into their account settings.

You can choose what information is visible on your profile, who can see it, and whether third-party apps have access to it. You should also consider turning off targeted advertising options so that companies cannot track your online activity.

Avoid Subscribing to Mailing Lists or Clicking on Pop-Up Ads

Mailing lists and pop-up ads may contain malware or lead to identity theft. Avoid subscribing to mailing lists unless they are from reputable sources like government agencies or well-known companies.

Pop-up ads can be especially dangerous because they often contain malware or redirect users to fraudulent websites. If you encounter a pop-up ad, do not click on it. Instead, close the window or use an ad blocker to prevent them from appearing.
