CiviMail uses a number of **action** and **mail-merge tokens** and which can be placed in mailing labels, PDF letters, email messages and message templates, mailing headers and footers, and system-workflow (automated) messages. These tokens are converted dynamically to text, reply-to email addresses, and URLs.
The best source of documentation for tokens is: <https://docs.civicrm.org/user/en/stable/common-workflows/tokens-and-mail-merge/>
This wiki page gives supplemental information for working with tokens. [You can also customize or create new tokens relatively painlessly](/framework/civimail/index.md##extending-the-token-system).
