FAQ
Why does Apple Mail dominate?+
It's the default mail app on every iPhone, iPad and Mac, and Litmus counts where an email is opened, not who hosts the mailbox. A Gmail or Outlook.com account read on an iPhone counts as Apple Mail. Litmus measured 62% in July 2026.
Is there a split by industry or for B2B?+
Not from Litmus. It publishes one list across all the senders it tracks, which leans towards consumer email. If you mostly email businesses, expect far more Outlook on your own list. Your tracker's email client breakdown is the number to trust for your list.
