# Configure Flow: Receive Email Trigger

# Configure Flow: Receive Email Trigger

The "Receive Email" trigger initiates a flow when it receives an incoming email to an email address specified by the system.  
It is possible to specify a list of permitted senders so that not every participant can trigger flows. If this list is empty, any sender can trigger the flow.

The following entities are available for the following functions in the flow:

* Sender
* Subject
* Message in plain text
* Message as HTML

The message in HTML format is only available if the receiving e-mail was also sent in HTML format.  
The plain text format, on the other hand, is always available.

A tutorial on how to do this in detail can be found here.
