  • Say more with fewer words. This is useful if you want to ensure that your subject line fits well on mobile devices.
  • Indicate the type of email you’re sending. For example,a clock emoji for flash sales or a Christmas tree emoji for holiday emails.

How to choose the right emoji for your subject line

An emoji in the subject line can make or break your email marketing campaigns. A wrong emoji can come across as unprofessional, or even offensive. It is important to consider the context of your message and your audience before selecting an emoji.

Below are some of the tips to help you choose the right emoji.

  • Make sure the emoji is relevant to the subject line or the email content. Don’t just use an emoji because it looks nice – make sure it adds meaning to the subject line.
  • Use simple, common emojis that everyone will understand. Don’t use obscure or rare emojis that not everyone will be familiar with.
  • Avoid using too many emojis in your subject line. A few well-placed emojis can add personality and flair to your email, but using too many can be overwhelming and make your email seem unprofessional. It’s best to use one or two at maximum.
  • Make sure the emoji is visible on all devices. New emojis keep coming every year which some older devices or email clients may not be able to display, so test it using tools such as Litmus before sending it to your entire email list.
  • Pay attention to the tone of the emoji. Some emojis can convey a different tone than you intended, so choose carefully.

Now that you know how to pick the right emoji for your email subject line, let’s look at what emojis are safe to use.

Which emojis are safe to use in email subject lines?

Different people use different devices to check their emails, which can cause emojis to appear differently on each platform. For example, the below image shows how a smiling emoji conveying the same emotion can look different on Apple, Google, and Windows devices. You can check the Unicode website to see how each emoji will look on different devices and which devices support them.

Another thing to consider is that some older versions of Windows and MacOS, don’t support most of the new emojis. However, you don’t have to worry about this if most of your subscribers use mobile devices to check emails, as Android and iOS have full support for emojis.

The newer emojis also come with various skin tones that most email clients don’t yet support. To avoid your emojis displaying wrongly, stick to the default yellow skin color.

With that said, let’s take a look at the most commonly used emojis in email newsletters.
