Send Test Email

Sends the action's email to a single recipient, so it can be checked in a real inbox.

Placeholders are replaced only by the values in customPayload, as in Preview Email Content. One test email is sent, in language when given and in the site's primary language otherwise.

The test needs an email content that the site owns: a preinstalled automation still sharing its template's content has to be updated once before it can be tested. Reading and previewing it work either way.

There's a rate limit on test emails per action, to prevent excessive sends.
