Every month, we\u2019re sharing the top trends and shifts we see with email client market share. Although we dive deep into our findings in our annual email client market share<\/a> blog post, we decided to take a closer look, month-to-month, to bring you up to speed with the latest insights.<\/p>\n

We found in looking at last month’s data, we had a bit of a glitch with our reporting. So this month, we\u2019re diving straight into data for June and how it compares to April\u2019s<\/em> email client market share<\/a> instead. But even more so, we\u2019ll be looking at it through the lens of Apple\u2019s recent announcement on Mail Privacy Protection going into effect this fall.<\/p>\n

Let\u2019s see how email client market share changed in June 2021.<\/p>\n

Top 10 email clients overall<\/h2>\n

The top 3 email clients are still Apple iPhone (iOS Mail), Gmail, and Apple Mail (macOS Mail). Although the rankings haven\u2019t changed since April, there have been some interesting shifts in each client\u2019s share of the market.<\/p>\n\"June\n

Apple Mail\u2019s total share across iPhones, Macs, and iPads has gone down a tiny bit from 51.1% in April to 48.6% in June. But that\u2019s still a huge<\/em> number, and we expect it to remain strong for many years to come.<\/p>\n

Unfortunately, this also means Apple\u2019s Mail Privacy Protection will have significant repercussions<\/a> to email marketing in general. Instead of feeling nervous about this data, let it empower you. Use it to identify \u201creal opens\u201d<\/a> so you can start adapting now to the future of insights and analytics<\/a>.<\/p>\n

In particular, the Apple iPhone continues to rank as the top email client overall, but Gmail isn\u2019t far behind at second place. In fact, Gmail has increased its share by almost 22% since April. This does mean, however, that the remaining email clients have decreased theirs.<\/p>\n

    \n
  1. Apple iPhone: 37.7%<\/li>\n
  2. Gmail: 34.9%<\/li>\n
  3. Apple Mail: 10.1%<\/li>\n
  4. Outlook: 6.9%<\/li>\n
  5. Yahoo! Mail: 4.7%<\/li>\n
  6. Google Android: 2.1%<\/li>\n
  7. Apple iPad: 1.2%<\/li>\n
  8. Outlook.com: 1.2%<\/li>\n
  9. Samsung Mail: 0.8%<\/li>\n
  10. Windows Live Mail: 0.2%<\/li>\n<\/ol>\n

    Opens by environment<\/h2>\n

    Mobile continues to outrank webmail and desktop email clients in the competition for email opens.<\/p>\n\"June\n

    We didn\u2019t look beyond the top 10 email clients in April, so for the rest of this article, we\u2019ll be comparing June\u2019s numbers to Q1 (January to March)<\/a>.<\/p>\n

    Mobile had a healthy lead in Q1, but the gap between mobile and desktop is now smaller, going from an almost 7-point difference to slightly less than a 1-point difference. This is likely due to Gmail\u2019s growing popularity. (Curious why we count Gmail as webmail? Learn how Gmail opens are reported in Email Analytics<\/a>.)<\/p>\n

      \n
    1. Mobile: 41.1%<\/li>\n
    2. Webmail: 40.4%<\/li>\n
    3. Desktop: 16.9%<\/li>\n
    4. Other: 1.6%<\/li>\n<\/ol>\n

      Keep in mind, another thing Mail Privacy Protection will prevent marketers from seeing is which device<\/em> emails are being opened in from the Apple Mail client. Similar to Gmail, Apple Mail opens won\u2019t differentiate between iPhone, Mac, or iPad. In other words, we\u2019ll lose even more visibility into mobile vs. desktop. So if you\u2019re wondering whether you should design and code emails for mobile, you\u2019ll want to view your own audience makeup now to see if it\u2019s worth the effort. You can find this information either in your email service provider (ESP) or with an email tool like Litmus Email Analytics<\/a>.<\/p>\n

      Most popular mobile opens<\/h2>\n

      When it comes to mobile email opens, there has been and continues to be a very clear winner.<\/p>\n\"June\n

      Apple iPhone takes the mobile email cake. However, it\u2019s worth noting that its piece of the pie is basically the same while Google Android has increased their mobile email client market share since Q1 by 43%. That\u2019s pretty significant, but don\u2019t expect anyone to take the iPhone\u2019s crown anytime soon.<\/p>\n

        \n
      1. Apple iPhone: 90.1%<\/li>\n
      2. Google Android: 5.0%<\/li>\n
      3. Apple iPad: 2.9%<\/li>\n<\/ol>\n

        Most popular webmail opens<\/h2>\n

        With Gmail gaining ground overall, it\u2019s no surprise that it\u2019s still #1 in webmail clients\u2014leaving other webmail clients even further behind than before.<\/p>\n\"June\n

        Gmail has over 13% more of the webmail email client market share than it did in Q1. And with Yahoo! Mail losing over 22% of its share, the gap between #1 and #2 has widened by 13.5 percentage points. Outlook.com, sitting at #3, increased its own share by nearly 21%, but its share is so small to begin with that it barely makes a dent.<\/p>\n

          \n
        1. Gmail: 85.2%<\/li>\n
        2. Yahoo! Mail: 11.5%<\/li>\n
        3. Outlook.com: 2.9%<\/li>\n<\/ol>\n

          Most popular desktop opens<\/h2>\n

          The macOS version of Apple Mail once again reigns supreme in desktop email client market share.<\/p>\n\"June\n

          Surprisingly, the exact breakdown of the most popular desktop email clients is almost identical to what it was in Q1. The only difference? Outlook grew from 40% to 40.1%, taking from the Other category of desktop clients. See? Barely worth mentioning.<\/p>\n

            \n
          1. Apple Mail: 58.9%<\/li>\n
          2. Outlook: 40.1%<\/li>\n
          3. Windows Live Mail: 0.9%<\/li>\n<\/ol>\n

            What will happen next?<\/h2>\n

            Overall, the key insight we\u2019re seeing for June is that total Apple Mail opens across all devices still sits firmly at #1 in overall email client market share. And with Mail Privacy Protection just around the corner, the need to personalize your emails is more important than ever since you\u2019ll be losing insight into valuable open data.

            Where did we get all this data?<\/strong> Our email client market share stats are pulled from millions of email opens, anonymously collected and aggregated with Litmus Email Analytics<\/a> from June 8-30, 2021. It highlights global trends across all industries and verticals. Some email clients may be over- or under-represented, particularly with mobile and webmail. This is due to image blocking or image caching, most notably with Gmail. Still curious? Learn how we get this data<\/a>.<\/p>\n
