+
+Please note that the public enviPath system is intended for non-commercial use only.
+We see that you registered using the email address {email}.
+If possible, we kindly ask you to register using an official email address that reflects your affiliation (e.g., a university, NGO, or research organization).
+
+If you would like us to update your account, simply reply to this email and let us know which address we should use.
+We will then change it in our system, and you will receive a password reset email at the new address.
+
+If you are registering with a company email address and are interested in commercial use, you are very welcome to book a meeting with us so we can discuss how we can best support you.
+To book a meeting, please visit https://envipath.com/book
+
+If changing to an affiliation email address is not possible, please contact us at registration@envipath.org
