Massive mailing with option to CC AND BCC

Hello community, recently we have started using Mac for developing our duties. There was a chance when having windows of downloading a mail merging tool as an add-on to word. This tool is only available for windows and now with iOS, we have not been able to find a replacement tool that could work with the word app for iOS.

The idea is for us to be able to send a massive mailing with the option of adding CC and BCC fields too.

Would appreciate it if anyone could lend us a hand and provide guidance.
