There is a truism in the Refinery29 office: If you want to get a response to an email, include a GIF. While not every office is GIF-sending-friendly, including one can be a great way to brighten a boring email or better express yourself — after all, there's a limit to how many exclamation points you should include.
But not every GIF is work-friendly. I once sent this GIF to my coworkers (best described as Obama-as-Beyoncé-on-a-pizza-in-space?) and just received blank stares. So don't be like me — next time you want to share a GIF with a colleague, go with one that's proven to work.
Here are 20 tried-and-true GIFs that have seen their fair share of Refinery29 inboxes.

That feeling when things finally ( finally!) come together.

Anticipating a surprise birthday party, raise, or job well done? Go with Ron Swanson.

And never underestimate the power of a "thank you" GIF. Like when someone gets the job done efficiently...

...Or does something you weren't expecting.

Or just really, really moves you with their actions.

And sometimes, you just need to express that "face palm" feeling.

As a bonus, here's a GIF you should probably keep to yourself (but hey, it's a feeling we've all had at one point).
