When using an email service, it is important to be careful. Although the platform is more private than social media, it is also the target of dangerous scams and vulnerabilities. Users can protect their security by taking certain steps and avoiding making mistakes, such as sending personal data such as CPF and RG in a message.

Although deleting e-mails is one of the main tips for those who want to keep their inbox organized, it is worth remembering that old messages can contain important documents, such as details of meetings, presentations and task schedule. Another point that must be taken into account before deleting an email is the risk of losing contact with someone, since the message can serve as a reminder of the person’s email address.

2. Download attachments from suspicious senders

Cybercriminals can use email attachments to spread viruses and other malicious files. Coup messages tend to have an alarming and urgent tone, and are passed on by entities of great importance and trust, such as banks or government institutions. So it is important not to download attachments from suspicious senders without first evaluating them.

A good option is to evaluate the file format: some extensions considered safe are GIF, JPG or JPEG, TIF or TIFF, MPG or MPEG, MP3, WAV, DOC, XLS and TXT. These formats are the most common in e-mail attachments, and represent different types of media. It is also important to be cautious with files with «double extensions», such as image.gif.exe. The only extension that matters is the latter. In this example, the EXE represents an executable file that will open automatically when downloaded. Files with double extensions are often misleading and malicious.

3. Accumulate emails in the inbox

Leaving accumulated emails in the inbox can be a problem, because in addition to taking up unnecessary space, they hinder the search tool and filtering demands that need more attention. To alleviate this problem, you can create filters so that emails from inconvenient senders, for example, are always forwarded to the trash or spam. It is also important to establish a criterion for deleting messages considered irrelevant.

4. Allow excessive apps access to email

It is possible to implement new functions to e-mail platforms with the installation of applications and add-ons, but it is necessary to pay attention to the privacy authorizations requested by the plugin before installing it. Be suspicious of services that request access to too much information, such as viewing all emails sent or received by the account.

These applications can sell the user’s email data to target ads and marketing. From browsing history to products purchased on the market, everything can be tracked. In addition, if someone has access to your email, you can reset your passwords, from your online bank to profiles on social networks.

5. AndSend emails containing personal data

Never send an e-mail that contains personal data, such as social security number, RG or even credit card or checking account. If it is necessary to pass this information on to someone, choose to do it personally. If this data falls into the wrong hands, a malicious person can impersonate you.
