title: Facebook Messenger Send Api - send to a big amount of users
body: <p>I have a bot over Facebook which people are subscribing for sports updates.</p>
  
  <p>I have 1,000 - 10,000 users I want to send out an update to.</p>
  
  <p>Currently, in small scales like 20 messages , I would use a Facebook Batch request.</p>
  
  <p>But, i'm not sure what would be the best way to send my messages in a large scale.</p>
  
  <p><strong>My two options are:</strong></p>
  
  <ol>
  <li><p><strong>Batch</strong> - limited to 50 requests per batch request. 
  I don't really know if I should expect a delay in the execution of the request.</p></li>
  <li><p><strong>Regular</strong> calls - I will iterate through my receivers and send each of them a message separately. 
  I'm afraid Facebook might block me for thinking i'm spamming, or I will exceed the rate limits.</p></li>
  </ol>
  
  <p>I have to say I was expecting a more generic method coming from Facebook since they are allowing users to subscribe for update through my bot, hence, I was expecting them to provide a guide on what are the best practices for sending the update users subscribed for.</p>
