getEmailContent loads the recipient-specific message body and its event
history. It accepts either Brevo’s email UUID or the message ID returned by a
send action.
Example
Inputs
emailId: string is required. account optionally selects the Brevo binding.
When the value is not a UUID, Automate.ax first looks up the first matching
transactional email record by message ID.
Output
Returns{ email, subject, body, date, events, attachmentCount?, templateId? }.
events contains { name, time }[]; templateId may be a number, null, or
absent. The action fails if the message ID cannot be resolved in the connected
account’s retained transactional logs.
