There should be campaign status report of Numbers of Delivered Messages and Numbers of Undelivered Messages.

and Option to resend on Numbers of Undelivered Messages.

Yes, That Will Be Useful

Currently we have all delivered, open, undelivered report everything in WhatsApp broadcasting.

For resend undelivered message option is actually not realistic for WhatsApp because, it's WhatsApp for some their hidden algorithm they didn't send the message. If you resend again, it will happen the same.

Thanks

you can provide a option to create a broadcast option with that undelivered / delivered numbers as a targeted and can do right
