In order to trigger when emails are opened, this must be paired with a separate Zap using the **Send Outbound Email** action, with the **Enable Read Receipts?** field set to `True`.

To test with a live email, send an email to yourself using your **Send Outbound Email** action (with read receipts enabled) and open it, then test this trigger immediately for samples. If you don't need to test with live data, click Skip Test to use static test data.

**Trial or Free Zapier plan:**

Email by Zapier

If you belong to one or more Zapier Teams, select your desired account.

List the inputs to accept from "Call a Sub-Zap" and they will show up as fields. Add the word "required" to the label if you would like it to be required in the calling Zap.

Will only list "Sub-Zaps", which require the use of both the "Start a Sub-Zap" trigger and a "Return from a Sub-Zap" action.

To properly use a "Call a Sub-Zap" action you must create another Zap that contains *both* the "Start a Sub-Zap" trigger and "Return From a Sub-Zap" action. For your convenience, you can use [this link to create a Sub-Zap](https://zapier.com/es/app/editor?create=true&template__0__selected_api=SubZapCLIAPI%400.11.0&template__0__type_of=read&template__0__action=start_subzap&template__1__selected_api=SubZapCLIAPI%400.11.0&template__1__type_of=write&template__1__action=return_subzap).

List the keys and values to return to the original "Call a Sub-Zap". For example, you could ask for an email address and use it later in the Zap. It is generally safe to add more return values, but be careful about removing items that parent Zaps may rely already on!

Build reusable Zap components and systems by building and calling "Sub-Zaps".
