Using emojis in a business email sign-off is not ideal since they can be viewed as unprofessional and disrespectful to the recipient. However, since they are acceptable, some industries and businesses, such as design and marketing, use thumbs-up and smiley face emojis. That’s why it is important to understand the recipient and the content of the email before you decide which emoji is suitable for the sign-off. For instance, a more formal and conservative industry should avoid using emojis since they stray away from the professional tone. On the other hand, a more casual and creative business might find emojis beneficial since it helps them to express their creativity. The golden rule of business email sign-off is always to determine if the conversation has a professional tone. A professional email does not need emojis in the sign-off. Instead, it would be best to stick a standard sign-off such as “Sincerely” or “Best regards” to convey a professional and respectful tone.
