# Send an Update to Everyone Who Used Another Form

Sometimes you need to reach people who submitted a different form than
the one you’re using to trigger the batch. Mass Email Notifications
makes this easy with the **Target Form** setting.

------------------------------------------------------------------------

## How It Works

1.  Create or edit a Mass Email feed on your control form.
2.  In the feed settings, select the **Target Form** that holds the
    recipients you want to contact.
3.  Choose the correct **Email Field** from that target form.
4.  Compose your subject and message (or use a notification template).
5.  Submit the control form — the batch will be created using the
    recipients from the target form.

------------------------------------------------------------------------

## Example

- You run a **Donations** form and an **Event Signup** form.
- To send a follow-up to everyone who registered for the event, set the
  target form to **Event Signup** and select its email field.
- When you submit the control form, the plugin will build a batch of all
  event registrants.

------------------------------------------------------------------------

## Tips

- Use **Conditional Logic** in the feed to further segment recipients
  (e.g., “Event = Gala Dinner”).
- Preview the estimated batch size after saving to confirm you’re
  targeting the right audience.
- Remember that deduplication rules apply — one email per address unless
  duplicates are allowed.

------------------------------------------------------------------------

This pattern is ideal when you have multiple forms collecting different
types of contacts but want to send updates across them without exporting
data.
