  2. https://www.signupto.com/news/email-marketing-posts/analysing-your-performance-on-mobile-devices/

user agent string im getting from sendgrid

  1. Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via ggpht.com GoogleImageProxy)
  2. Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E; Microsoft Outlook 14.0.7172; ms-office; MSOffice 14)

Have you tried parsing the UA string?

When I run those through an online parser I see distinct data.

In general though, SendGrid, yourself, and everyone will be limited by what comes back in the UA string. But then again, how many people do you know who read their email from their cell browser, vs their phone's app? I think that's a very small edge case, and wouldn't worry about it.
