This tutorial shows you how you can use NutriAdmin to send a mass/bulk email to some of your clients with useful messages, daily reminders, etc.
The client can receive the email and simply read it. On the other hand, the client can also interact by clicking the questionnaire button that will be included in your email and filling in any data you have pre-configured.
This can be a great way to do marketing, to keep clients accountable, and to increase compliance with dietary guidelines.
