title: hubspot3 client and "too many retries" error
body: <p>I'm trying to pull the details for a contact from hubspot using the recipient's email.  I'm using the python3 client "hubspot3" (<a href="https://github.com/jpetrucciani/hubspot3" rel="nofollow noreferrer">https://github.com/jpetrucciani/hubspot3</a>).</p>
  
  <p>Here's the code I'm submitting:</p>
  
  <pre><code>import requests
  from hubspot3.contacts import ContactsClient
  
  API_KEY=[myapikey]
  
  client=ContactsClient(api_key=API_KEY,debug=True)
  
  email='mytest@gmail.com'
  
  client.get_contact_by_email(email)
  </code></pre>
  
  <p>The response:</p>
  
  <pre><code>WARNING:root:Too many retries for /contacts/v1/contact/email/nwnippy27+cb1@gmail.com/profile?hapikey=[myapikey]

  <p>I'm reading this error as saying that the email address can't be found.  Is that correct?  If not, I appreciate any intel on the cause and solution.</p>
