How It Works:
Use !{parameter} placeholders in the Subject and Body. These placeholders will be replaced by each recipient's details from the table below.
Example:
Subject: Meeting with !{name}
Body: Hi !{name}, your appointment is on !{date}.
For john@example.com, with: name = John, date = 2025-06-01
The email sent will be: Subject: Meeting with John Body: Hi John, your appointment is on 2025-06-01.
