Things to keep in mind when using
emoji in email subject lines

From 😘 to the open-inducing ⛄, there are heaps of emoji to choose from, but not all of them show up properly on different mobile devices and email clients. If this happens, subscribers may see this ▢ or just the word ‘emoji’ instead of your intended icon. That makes marketers feel 😢.

Email client support for emoji

As marketers, we have to keep in mind that there are many different email clients out there like Outlook, Gmail, Apple Mail, Thunderbird, etc. And, all these email clients don’t render email the same way (wouldn’t that be a dream!)

Because we can’t force all the email clients to play nice and render our emails the same way, it’s important to know that your emoji may look different in the different clients. So how do you know which email clients are particularly problematic for emoji?

To see what would happen when we included emoji in our email subject lines, we tested a variety in the most popular email clients and found they were generally well supported:

Emoji Support email clients

With the exception of Outlook 2003, there was near-universal support. and iOS devices included an additional twist – instead of displaying the basic characters, some symbols like ❤ are replaced by the word ’emoji’, or a small graphic instead.

emoji in email

With an Android device, you can insert an emoji using the appropriate button on the standard Android keyboard. However, emoji inserted in this way will be visible in Inbox on Android but not necessarily in the web version.

Keep in mind that if a emoji isn’t supported in the email client, the recipient may see a ☐ character instead.

Using emoji in your email subject lines can be an effective and attention-generating technique to increase your email open rates 🎉 and get more people engaging with your campaigns.
