If you're an iPhone Mail user and you want to send an email to more than one person, you can line them all up in the To field. A long list of email addresses not only makes for an unsightly, unwieldy message header, however; it also reveals all addresses to every recipient.

This procedure has been tested using iOS 12.

How to Blind Copy Recipients in iOS Mail

Use the Mail app's Bcc field to send blind copies:

  1. Create a new message, then tap the Cc/Bcc, From line to expand it. If you've only added a single email account to your iPhone, the line will show as Cc/Bcc only.

  2. Tap the Bcc line then add one or more addresses.

  3. Add at least one To addressee. To send it to yourself using the "Undisclosed Recipients" line, add a new contact called Undisclosed Recipients and use one of your own email addresses. This specific sender name is an informal internet standard to signify that the real distribution list has been blind copied.

  4. Compose and send your message as normal.

The people who receive your email won't be able to see any of the other addresses to which the email was sent. If appropriate, you can add a note to explain that your email was sent to other people; you might even include their names — but this way, you won't need to divulge their email addresses, or risk a cascade of reply-all correspondence.
