# Transactional tags

{% hint style="warning" %}
**If you use a transactional template that has already been tagged, additional tags used in the header or API request are discarded.**
{% endhint %}

Create transactional mail streams with their own analytics by including a tag with the message. 

Messages sent without a tag will be grouped together as 'untagged' on the transactional dashboard.
