True or False: Using emojis in subject lines and headings has a negative impact on engagement.

False. Research and common marketing practices demonstrate that using emojis in subject lines and headings can actually increase engagement. Emojis can make content stand out in a crowded inbox or feed, convey emotion, and quickly communicate information, leading to higher open rates and click-through rates. The key is to use them appropriately and in moderation, ensuring they align with your brand voice and target audience. Overuse or irrelevant emojis can indeed have a negative impact, but strategic use is generally beneficial.
