Thank you for your interest in enviPath!

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

Best regards,

enviPath team"""
