# Settings & configurations
> When you first open an Extract from email step, a configuration panel opens on the left. This lesson serves as an overview of the settings and how you can customize the step based on your workflow.
***
## Your flow's email address
At the top of the panel is the unique email address for this flow. Any email sent to this address will trigger the flow/step to run and pull in data.
All Extract from email steps within the **same flow** share one email address. Different flows each get their own unique address.
### Flow email settings
Below to the email address is a **gear icon**. Clicking it opens the flow email settings modal, where you'll find advanced configuration options.
It's worth knowing that the options exist, but for your first flow, the default settings will likely do the trick.
| Setting | What it does |
| ------------------------------------------- | -------------------------------------------------------------- |
| **Reject emails without valid attachments** | Only processes emails that include a supported file attachment |
| **Only process CSV/TSV files** | Ignores any attachment that isn't a CSV or TSV |
| **Run the flow once per email** *(default)* | One flow run is triggered per email received |
| **Regenerate email address** | Creates a new unique email address for this flow |
| **Run the flow once per attachment** | One run is triggered per file — useful for batch emails |
**Run once per attachment** is especially powerful when vendors send multiple invoices or reports in a single email. Each file will be processed independently and in the order it was received.

## Pull data from
This dropdown controls what data source the step reads from.
Reads only from the file attached to the email. The email subject, body, and sender info are not included.
Reads from the email itself — subject, body, sender, etc. — without looking at any attachment.
Reads from both. This is how you bring in file metadata (like file name and file URL) alongside attachment data in the same step.
***
## File attachment type
Once you've chosen your data source, a second dropdown appears for the **file attachment type**. Options include:
* **CSV/TSV**
* **Excel**
* **JSON**
* **PDF (with AI)**
* **PDFs (multiple formats, with AI)**
Lessons 3–6 cover each file type in depth.
***
## File URL access
When **Email content + attachment** is selected, you get the option to pull in a `file_url` — a Parabola-generated link that lets anyone with access download the original file from their browser.
The `file_url` is especially useful for audit workflows. Include it in your exported data or reports so reviewers can always trace a row back to its source document.
You control who can access this URL:
* **Anyone with the link**
* **Anyone within your Parabola team**
* **Only those with flow access**

## What's next
Now that you know where everything lives, let's put it to work. The next lesson covers extracting data from CSV and Excel file attachments.
***
Within your flow, add an **Extract from email** step onto the canvas, either by asking Parabola to add the step or using the search bar.
