Subject Lines With Emojis

Another great tip to bring your halloween email subject lines to the next level is to use emojis. While emojis are certainly fun, it’s important to be aware of some consumer trends when it comes to Halloween emojis. 🤔

Don’t go adding emojis to your subject line like jump-scares in a haunted house! Remember your halloween newsletter is part of a holiday email marketing campaign—not your neighborhood trick or treat. A Return Path study found the spider 🕷 and cobweb 🕸 emojis to be popular in halloween email campaigns but that subject lines with these emojis had lower open rates. 

Of course, there are plenty of gory and gruesome Halloween-themed emojis at our disposal (🩸 ⚰️ 🗡️ 🪱 etc…). But these are too much for a marketing campaign! Instead, take a look at the examples below for the perfect Halloween emojis:

  • 💋 Get Vamped Up for Halloween! 🧛🏻‍♀️ – Memebox
