Agree mail from client after sending him a contract

Here's an example of an email you could send to a client after sending them a contract:

Subject: Confirmation of Contract Receipt

Dear [Client Name],

I hope this email finds you well. I wanted to follow up on the contract I sent to you earlier today regarding [project/service name]. I wanted to confirm that you have received the contract and to answer any questions you may have.

I'm happy to work with you to ensure that everything is in order.

If you're ready to move forward, please sign and return the contract to me by [date]. This will allow us to begin work on [project/service name] as scheduled.

Thank you for your prompt attention to this matter. I look forward to hearing back from you soon.

Best regards,

[Your Name]

This email serves as a polite reminder to the client that you've sent them a contract and gives them an opportunity to ask any questions or raise any concerns they may have. It also provides a clear deadline for them to return the signed contract, which helps to keep the project on track.
