BCC (blind carbon copy) lets you send an email to multiple recipients without revealing their addresses to each other. Learn best practices and common pitfalls.
BCC stands for Blind Carbon Copy. It allows you to include recipients in an email without exposing their email addresses to other recipients. BCC is commonly used when emailing groups where privacy matters.
BCC can help prevent accidental reply-all chains and protects recipient identities in announcements. However, it can also feel impersonal if used for outreach, especially if the message reads like it’s meant for one person.
A good rule is to use BCC for announcements, introductions (carefully), or internal visibility. For marketing campaigns or personalized outreach, use tools built for individual sends instead of a single BCC blast to reduce deliverability risk.
