  TL;DR - Based on your calculations you are considered a high volume sender and would be a candidate for a dedicated IP address in AWS SES
  
  I was unable to find a source where AWS specifically enumerates what they consider to be high volume e-mail sending. Other sources vary (or are vague) about what they consider high volumes (see references below). From those sources I think you can safely say 100k e-mails a month is the high volume threshold.
  
  Note that there are several pros and cons to using a dedicated IP address that you should consider as well.
  
  **Pros**
  
  * Good for high volume senders
  * Your reputation username_0 be your own
  * Your IP is more likely to be safe-listed by ISP's
  * You can isolate your reputation by e-mail type, recipient, etc.
  * The IP address username_0 never change
  
  **Cons**
  
  * It requires additional setup and time to build reputation (and keep it)
  * You manage your own reputation
  * Not good for unpredictable sending patterns
  * Additional monthly cost
  
  Your dedicated IP address needs to warm up before it username_0 be accepted. You'll also need to keep a steady volume to maintain that reputation.
