Whether a thumbs-up emoji is a good response really depends on the situation.

If it's a quick 'yes' or 'okay' to a simple question, it's fine. But if someone's asking for your opinion or needs more details, it can seem like you're not putting in much effort.

Also, how well you know the person matters a lot. You might use it with a close friend. In contrast someone you don't know well, it can be considered rude.
