Tips for Hitting Inbox\’s on the Top Email Providers (Gmail, Yahoo, Outlook) We’ve all been there – struggling to send a perfectly-targeted campaign, trying to figure out which clients our audience uses, and wondering how we can make sure our email looks and sounds great no matter where and how they’re viewing it. What can possibly solve these problems? Luckily, if you’re struggling, we’re here to help. We recently published our report “The Path to Email Engagement in 2021,” which highlights the latest email trends and user habits – and that includes research into today’s top email clients. Since the 1990s, email has become a prime method of communication for people all over the world, with many clients to choose from. Email sending success depends on knowing about these clients, their differences, and similarities. In this article, we’ll take a look at the top providers and provide some tips on sending to them all. Let’s continue and look up over the cutting edge of email.

Like most things email, there is no one-size-fits-all answer (i.e., everyone uses AOL Mail!) that we can pinpoint. However, there are useful trends that offer us insight into global user habits. The popularity of email clients and platforms differs by location, and many people have more than one email address. This means that, when sending, you should be aware of which providers your audience is using the most. Top email clients around the world Our research revealed that, overall, Gmail remained the most popular email client – 65.3% of our global respondents reported using it. It’s most popular in the United States (its country of origin, so not too surprising) and Spain. 76.3% of American respondents and 74.6% of Spanish respondents reported using Gmail. On the other hand, it’s least popular in Germany, capturing “only” 52.9% of users. When it comes to second-choice providers, different locations had different favorites. In the United States, Yahoo is the second-choice option for personal emails (14.2% of users). Outlook takes a healthy third place (6.5%), and Comcast is last with a barely-there 0.7% of users. In Europe, Outlook is the more popular second choice in France, Spain, and the UK (with 19.7%, 20%, and 30.6% of users respectively). It’s third in Germany (12.6%), just behind Germany’s Web.de client. If you’re sending to European countries, you won’t find many Yahoo addresses in your lists: Yahoo is a distant third in all European countries, with a single-digit presence in each location. How people check their emails When it comes to the platforms people use for these clients, mobile is still the most popular way to check emails overall. Gmail’s mobile app is the most popular app used to check email (which makes sense, given Gmail’s overall huge popularity). However, mobile is just one part of the story. Most people don’t check their emails only on one platform. They use a mix of mobile and desktop depending on what’s convenient (in line at the store? Mobile. Working on your laptop? Desktop). Also, when it comes to desktop email, checking email via browser has a big lead over checking via the app. This data gives senders an important message – do not ignore either mobile or desktop platforms, or browser or app usage when creating email. Some may be more popular than others, but all have enough audience share to justify making sure that your messages look great everywhere. Okay, now that we all know a little more about general email usage, let’s take a look at the top three email providers, how they organize mail, and some best practices for each. What to remember when sending to the main email clients You might be wondering: Does it really matter whether or not you follow certain practices for each email client? After all, they’re mostly the same, right? Sorry, you’re not off the hook. While the main email clients have many similarities, it’s important to remember that they all have differences in layout and message rendering that can affect your emails. Let’s explore how each email client displays mail, and look at a few tips for sending it to each. Sending emails to Gmail Unsurprisingly, the ubiquitous Gmail is still the king of the email clients (you may even have it pulled up via app or browser right now). As we’ve mentioned, a whopping 65.3% of global email users use Gmail, and it’s the leading client across all of our surveyed countries. 76.3% of our American respondents use it, and its lowest showing in Europe was a 52.9% share in Germany – still over half of respondents. It’s kind of a big deal. In both mobile and desktop formats, users can choose to enable or disable the Tabs feature. About half of Gmail users (53.3%) use Tabs to sort their mail, and the other half leave their mail unsorted. While the Tabs feature isn’t used by everyone, it’s still a factor you need to keep in mind when planning for better deliverability. Most people (79.7% globally) check it at least once a week, and a half (51%) do it daily. How Gmail organizes emails Gmail uses Gmail Tabs to organize its recipients’ mail into a series of categories. These tabs include Primary mail, Promotions (which includes marketing emails like yours and brand offers and discounts), Social (which includes social media notifications and dating and social websites), and more. If you want to check what tab your email will land in, leverage tools like Inbox Placement.
