What type of email is utilized for collecting necessary documentation and assessments for starting a training program?

Onboarding emails are specifically designed for the purpose of guiding new clients or participants through the initial steps of a program. They facilitate the collection of necessary documentation and assessments required to begin a training program. This type of email typically includes instructions on what information is needed, how to submit it, and possibly a welcome message that helps establish a connection between the trainer and the new client.

While informational emails provide knowledge about services or processes, they do not usually focus on the initial setup for a client. Promotional emails aim to market services and attract new clients rather than assist them in getting started. Engagement emails are used to maintain contact with current clients and foster ongoing communication, but they are not intended for the initial documentation and assessment phases associated with onboarding a new client. Therefore, the choice of onboarding emails is the most suitable option for this context.
