Acoustic Campaign lets you quickly send targeted emails to groups of leads and contacts and then track engagement metrics. However, you can send an Acoustic Campaign email from a Salesforce campaign only one time.
When you send an email from Salesforce Campaigns, you can choose the template that accompanies your message. If you want to add any text in addition to the content in the template, you must choose a template with an asterisk * in front of its name. While you are composing the emails, the fields that are preceded by red vertical lines are required fields. If you choose a template that does not have an asterisk that is preceding its name, then in the Personal Message area you are not allowed to add a personal message to the contact. When your message is complete and you are sure that everything is set exactly as you want it, you can use send the email to complete the process and send your personalized message.
