Note: You can only message a creator you actively pledge to or have successfully pledged to in the past.
There are two ways you can message a creator you are supporting on Patreon:
1. From the "overview" section of a creator's page, click "more" on the left-hand side and then "message."
2. Navigate to the side menu on the left side of the page while signed into Patreon.com and click "messages."
From there, you can enter the name of any creator you are a patron to into the text field and you'll see a message box pop up.
Note: If you have been blocked by a creator you will not have any permission to message the creator.
