In Outlook (and email generally), CC (Carbon Copy) sends a public copy to people who need to be informed, allowing all recipients (To, CC, and BCC) to see each other's addresses for transparency; BCC (Blind Carbon Copy) sends a private copy, hiding recipients from everyone else, ideal for mass mailings or protecting privacy, as only the sender knows who received it, say Microsoft and VITG. CC fosters open communication, while BCC ensures discretion, preventing reply-all storms and protecting identities.
The CC recipients' email addresses will be visible to all other recipients. You should use BCC (blind carbon copy) when you want to secretly include additional recipients without disclosing their email addresses to the other recipients.
If you're being disingenuous or intentionally hiding your professional practices, BCCing is a way of worsening your ethical breach. Be honest, and try not to use the BCC field for sneaky, fraudulent, or insincere purposes.
Similar to the more commonly used cc (carbon copy), the meaning of bcc is “blind carbon copy.” Unlike cc emails, recipients under bcc are hidden from everyone but the sender. Recipients copied under bcc won't receive email replies from other recipients.
Bcc is useful if you prefer to keep recipient email addresses private. It also means that the bcc'ed recipients will not receive any reply emails from the other recipients, even if they select “Reply all”.
If you send bulk emails often, it's possible to accidentally carbon copy (CC) the recipients instead of BCC-ing them. You could also send a direct email to your recipients by mistake instead of BCC-ing them. In both instances, you can unknowingly reveal others' email addresses to unknown people.
The primary drawbacks of BCC are the risk of misuse and the potential for incomplete or confusing communication threads.
Is it rude to use BCC? It's not necessarily rude to use BCC. Using BCC is acceptable when done in the appropriate contexts, such as protecting recipients' privacy in mass emails.
Is there any way for the other recipients of the mail to find out who was Bcc'd? The simple answer is no. No one in the To, Cc, or Bcc lines will know who was Bcc'd. Only the sender can look in their sent folder to see the full list of who received the mail.
The "+1 email trick," also known as plus addressing, lets you create infinite email variations for a single Gmail account by adding +anything after your username (e.g., [email protected]), with all emails still arriving in your main inbox. This is great for filtering spam, identifying data sellers (if [email protected] gets spam, you know Facebook shared your info), and organizing subscriptions without needing new accounts.
There isn't one single "most hacked" provider, but Gmail (Google) and Microsoft Outlook are the most targeted due to their massive user bases, making them prime targets for attackers, with reports showing massive increases in attempts against Gmail and Microsoft being the most impersonated brand in phishing. While these giants face high attack volumes, their security is robust; services like Proton Mail and Tuta (Tutanota) are considered more secure for privacy due to features like zero-access encryption, though they are less frequently targeted because of smaller user bases.
No one who receives the email can see bcc recipients, and bcc recipients can't see each other either. Where did the term blind carbon copy come from? Before we used email, we used paper letters.
Unprofessional emails often suffer from issues like rambling, gossiping, and going off topic. Rambling occurs when the email goes on and on without getting to the point. The recipient may find it challenging to understand the main message or even keep reading to the end.
While using cc can be a great way to connect colleagues or clients, avoid using it if you're unsure whether the recipients would want their contact information shared with others on the email. Be careful when using reply all on emails that include cc'd recipients.
The practice should be frowned on by companies unless there is a legitimate, specific business reason for the copy. If you're negotiating contracts or proposals that need to be reviewed by everyone in the chain of command, copies are required.
Addresses that have been placed in the BCC field are not forwarded. If you have placed a large list of recipients in the To or CC field, all of them will receive the reply. By placing recipients in the BCC field, you can help protect them against receiving unnecessary replies from anyone using the Reply All feature.
From poor deliverability to data privacy risks, using the BCC field is not a reliable or professional solution.
BCc is best used when emailing a group of folks; you do not want to expose their email addresses. It is also a way of hiding an extremely long list of email addresses for blast emails where it isn't necessary to know who the email was sent to.
Gmail read receipts are a feature that allows senders to request a notification when their recipient has opened their email. This functionality provides confirmation that your message has not only been delivered but also viewed by the intended recipient.
The "3 Email Rule" is a productivity guideline suggesting that if an email conversation goes back and forth more than three times (three messages sent and received), it's time to switch to a more direct communication method, like a phone call, video chat, or in-person meeting, to avoid miscommunication, clarify issues, and save time. This rule helps resolve complex discussions efficiently by leveraging richer communication channels that include tone and non-verbal cues, which emails lack.
Failure to use BCC correctly in emails is one of the top data breaches reported to the ICO every year – and these breaches can cause real harm, especially where sensitive personal information is involved. When you use the 'BCC' field to send an email, the recipients can't see each other's email addresses.
In Microsoft Outlook, you can specify that for all messages that you send, an automatic carbon copy (Cc) is sent to other people or distribution lists. One scenario in which this rule is useful is when all members of a team are responsible for responding to incoming email messages, such as a support center.
Rules for email etiquette
Note: When you add someone's email address to the Bcc (blind carbon copy) box, a copy of the message is sent to that person. Other people who receive the message don't see whose address is on the Bcc line.
