title: Why declare viewport in html email campaign?
body: <p>The majority of HTML emails and boilerplate that I've seen coded by other people, always declare a viewport meta tag.</p>
  
  <p>I mindfully always avoid declaring a viewport and strive for a very high level of cross/backwards compatibility.</p>
  
  <p>Declaring viewport settings render the email totally unusable for any of your audience using a Blackberry and overall is very poorly supported by any client.</p>
  
  <p>Is there a reason to use this tag that I missed?  Why are the majority of other peoples emails I see using this?</p>
