When Can Lawyers Start Using Reaction Gifs?

Question for my lawyer friends: Have .gifs become widespread enough that we can start including reaction .gifs in emails to insurance adjusters and opposing counsels? Or, do I have to wait a few more years for the technology to become more commonplace before this is appropriate?

I feel like including .gifs would help me advocate for my client and communicate more clearly with others.
