Sending a mass text without showing all recipients can be done by using the BCC (blind carbon copy) feature. First, compose a new text message and enter your message content. Next, instead of selecting individual contacts, enter the phone numbers of all recipients together in the BCC field. The BCC field will hide all recipients from each other, ensuring that their numbers and identities are kept private. Once you've added all the numbers, hit send. This is a convenient and efficient way to send a mass text while keeping the privacy of all the recipients intact.
