Open letters are written communications addressed to a specific person or organization and made publicly available. They can be used to bring attention to an issue, request change, or express an opinion. Open letters have a long history, with famous examples written by activists, thinkers, and leaders.

In this post, we’ll explore what open letters are, when you should write one, look at examples, and provide tips for crafting an effective open letter.

What is an Open Letter?

It’s pretty much what it sounds like – a letter that’s open to the public. Unlike sending a private note to your pen pal, open letters are meant for everyone’s eyes.

These letters are addressed to a specific person or organization, but instead of sealing them in an envelope, the writer publishes them where the whole world can see. You’ll find open letters posted online, printed in newspapers, passed around at protests.

The goal is to get the message beyond just the recipient. Open letters allow you to speak out publicly and rally people around a cause.

  • To express concern about a policy, event or situation
  • To offer an opinion or perspective on an issue
  • To criticize an action or statement
