My apologies if I wasn't clear enough. I don't want all the recipients to also need whatever app I use. I just thought maybe there was an app that would allow me to put 100+ names on a particular text announcing a meeting or event or something similar. I just thought it could be sent to their regular "messages" (aka text).

If they need the same app I use, that won't happen.

But, maybe there's something like I am seeking.

Thanks
