"Dear Mr. Rodriguez,

I hope this email finds you well. I am writing to follow up on our previous discussion regarding the enterprise solution proposal. Please do not hesitate to reach out if you require any additional information.

Sincerely,
Andres"

Hope you had a great weekend! Just wanted to follow up on the proposal. I made those pricing adjustments we talked about. Let me know if you need anything else!

Best,
Andres"
