I've been chatting with this person on X.com regarding a sponsorship on behalf of Redbull. They sent me an NDA and I am not sure if this link is real or not.

Here is the link https://joindocusign.com/

This was the final message leading to the NDA “

We work with Docu under our corporate agreement, using their internal resource. All connections are made locally from the user's device, making it part of the web session and ensuring uninterrupted access to information.

Follow the instructions to review the NDA agreement: 1. Open your browser and navigate to the Docu service's subsidiary website: https://joindocusign.com. Enter your personal key - ???????????????? - in the "Invitation Code" field to access the document package. 2. After entering the code, you will be redirected to the document page. Click the "Edit Offline" button. 3. Open the app and re-enter your personal key (????????????????) to confirm access. Review the information and sign the NDA.”

I personally put question marks instead of the actual numbers and stuff.

I then told them “I just wanted to confirm the legitimacy of this sponsorship opportunity. While I do see the LinkedIn profile mentioned, I understand that such profiles can sometimes be replicated. Since I don’t own a LinkedIn account to message 'Julia Leeb,' do you have access to an official Red Bull email address that you could use to contact me? Or is there an alternative method I could use to verify the authenticity of this collaboration?” 

They responded with - “Yes, of course, you can find the official contact information on our website http://redbull.com. Usually, communication is sent from the email address info@redbull.com. Immediately after signing the NDA agreement, we will send you all the materials from this email address.”

Please and thank you.
