Is it a mistake to use emojis or casual language in professional emails?

[Btaliat]

You need to find a way of monitoring your clients in such a way that you will know what exactly they like. You need to realize whether they are the type that fancy using emojis or not. When you make use of emojis, you are humanizing that conversation. But when you overuse it, it makes it seems like you don't respect the conversation. That is why it is always better to limit the way you make use emojis.
