CCO Hidden Carbon Copy: What is it

One of the most frequent things done in emails is to send a message to several recipients , whether to share some important information, survey or some text funny. However, every time we add several recipients in a message they usually appear visible for all emails added.

Keep in mind that some of them may not want their email address to appear there, even more when it comes to other people they don’t know. In these cases, before sending an email we can find two types of options CC and CCO.

CCO is a copy of hidden or hidden carbon , and this simply reflects the old carbon paper method they used manual invoices or typewriters . It will be responsible for hiding each of the recipients. For this, here we explain a little more about what this function is about.

What is the «hidden carbon copy» or CCO of an email electronic?

¿Qué es la

This function known as “With hidden copy” or “Carbon copy hidden”, is used for those cases where you need to send the same mail to different users and You don’t want one person or several to see the rest of the recipient. It is mainly used to avoid revealing the identity of other users and at the same time have more privacy when sharing some information via email.

Therefore, the best solution for all this was to enable a Cco box where users can write down each address and prevent them from spreading next to the message This also serves to send good morning messages or congratulations simultaneous and that arrive individually to each of the recipients, which will make them feel more special when you notice that there are no other addresses attached there.

Is it possible to hide the CCO of mails that I send to multiple recipients? Benefits of doing it

  • Prevents viruses and malware , by not receiving messages from strangers you It will help to protect against malicious software, given that these cybercriminals frequently subscribe to email address lists where they use it to share their malicious activities. Therefore, the more hidden your address is, the more secure your account will be.
