After WellerDeveler DraftPilot
Hi John,

I wanted to follow up on our conversation last week regarding the proposed meeting. I haven't received a confirmation yet, and I want to ensure I can plan my schedule accordingly.

Could you please confirm whether we're still moving forward, and share an update on the proposal as well? I'd appreciate a response at your earliest convenience.

Thank you,
[Your Name]
