How was only one recipient visible in the "to whom" field during a mass mailing?

Question

Email

For example: a letter is sent to 20 recipients (all of them are in the Bcc field). I send with the mail() function.
In the "To" field, you have to write, for example: [email protected]
And how to make it so that each recipient sees only himself in the "To" field, and does not see others?

Answer 1

Write in the To field - the address to which you should reply, that the thread is like [email protected]
If someone answers the letter, it will only come to you.
You specify recipients in Bcc.
And you will find happiness.

Answer 2

foreach ($mails as $mail) { ...Тут отправка каждому отдельно... }
