### <mark style="background-color:orange;">**Important Warning Regarding the Use of Yoplanning's Email Sending Features**</mark>

***Note that the restrictions below do not apply to SMS messages, but only to emails***

Please note that while Yoplanning offers email and SMS notification features, there are significant restrictions on their use. Yoplanning has a specific license for sending notifications, meaning that the messaging features must be used exclusively for sending informational or notification emails, and not for commercial communications.

It is imperative not to use Yoplanning for sending commercial messages, such as early-season reminder emails to boost bookings. These practices could be interpreted as spam and negatively impact the reputation of your organization as well as that of Yoplanning.

If you need to send emails for business purposes, we strongly recommend using a dedicated tool specifically designed for marketing communications. This will not only ensure compliance with applicable standards and regulations but will also help maintain the efficiency and reliability of Yoplanning's notification systems.

Your understanding and cooperation are essential to ensure an optimal user experience that complies with digital communication legislation.
