# Overview
You can use Responsys to send triggered messages to your contacts. Using this action, contacts will receive an email containing the [Responsys campaign template](🔗) selected in the action. To edit the Responsys template, visit the [Responsys Help Center](🔗) to learn more.
Considerations & Use Cases
This action alone _doesn't_ result in a contact receiving an email. You need to set up an automation in Responsys to use the PET for a send.
If the API triggered send requires [custom context](🔗), those fields _won't_ pop up automatically in the flow action window to configure the field values (custom context).
# Configuration Parameters
| Parameter | Description |
| ** Responsys Campaign Name ** | Name of the campaign within Responsys. |
| ** Custom Context ** | Custom context values for personalization. |
| ** Frequency Cap ** | Number of sends per contact per period of time. |
