Subject: [Company] volunteers needed for our AI implementation (Catalyst Contract Review by Onit) 

Dear Colleagues,

I hope this email finds you well. As [Executive Sponsor's Name] mentioned in [his/her/their] email sent on [date sent], I am the lead and main contact for this implementation project. To get started, I will be looking for Contract Review Subject Matter experts for [contract type(s)] as well as 1-2 additional volunteers to give input on building the Playbook and testing the Contract Review tool.

On average, Onit estimates that the time commitment will be 2-3 hours per week, for ~4-6 weeks per Playbook, although the time commitment may lessen as we get closer to completion. This work could include gathering documents to share with the Onit team, assisting in Playbook customization, and testing and providing feedback to Onit to refine the results. 

If interested, please reply by EOD by [date] to let me know, and I will confirm our list of volunteers after we meet with Onit to finish planning the next steps of the implementation process.

We are excited about the possibilities Catalyst Contract Review offers and look forward to seeing the benefits it will bring to our work. Your input and support will be crucial to the success of this initiative.

Thank you for your cooperation and support. 

Best regards,

[Your Name]
