Use Case

Cirrus Computers, a multinational hardware company with technical support agents in ten support centers throughout the world, wanted to customize the Email action to increase standardization in outgoing messages and to limit the fields agents could edit.

Cirrus used the apex:emailPublisher component to create an Email action that:
  1. Has read-only To and Subject fields.
  2. Pre-populates those fields, ensuring consistency and increasing agents’ efficiency when writing email messages.
