What must be included in an email template for Dynamics 365 Customer Voice?

For an email template in Dynamics 365 Customer Voice, including the email subject is essential because it serves as the first point of contact with the recipient. The subject line captures the recipient's attention and gives them a clear indication of the email's content, which is critical for encouraging engagement and responses.

Having a well-crafted subject line can significantly impact open rates and ensure that the message is perceived as relevant and important. It sets the tone for the email and helps recipients prioritize their email reading. While company branding elements, recipient demographics, and sender's contact information can all enhance the overall effectiveness of an email template, the email subject is fundamental as it directly affects whether the recipient will open and read the email.
