title: One API call to send SMS to multiple users (Twilio)
body: <p>I have a list of ~50 phone numbers I need to send the same SMS to via Twilio's API. How do I do that (via Python)? </p>
  
  <p>I can do it in a for loop like so:</p>
  
  <pre><code>from twilio.rest import Client
  client = Client(SID, AT)
  
  for number in number_list:
      client.messages.create(to=number, from_="+18328955063",body="foo bar")
  </code></pre>
  
  <p>But instead of hitting Twilio's API multiple times, I'd rather send an array/list of phone numbers in bulk and just make one API call. So how do I do that? Is it possible at all? </p>
  
  <p>I'm setting up a background async task to take care of outgoing text messages, and ideally wouldn't want my task to wait a long time while Twilio processes the messages one by one. I'd just want to send over a list of numbers as payload and be done with it.</p>
