# Tags
This functionality allows you to automatically tag a group of emails, thus marking them with appropriate labels.
1. Go to **SMTP Accounts tab > Settings > Tags.**
2. Choose one of the following ways to tag your emails:
* **Adding the rule for the “From” field:** the tags will be added based on the sender’s email address.
* Adding the “Subject” field rule: the tags will be added based on the email’s subject line.\
If you choose to label your messages based on the subject line, you can use the “\*” sign - it will mean that there might also be other characters besides the searched-for ones in the subject field.
**Example:**
* **“Searched phrase\*”** - the system will find the searched phrase and everything that comes after that.
* **No “\*”** symbol means only the searched phrase will be found.
3. Fill in the **“Tag”** field and click the **“Add rule”** button.
You can also find the list of all used tags in the Administrator tab > Tags.

**Important!** You can add tag rules even when the functionality is not turned on. Select the “Turned on” option to enable it and click the “Save” button.
