“Thank you for your approval” is appropriate when someone has formally authorised a request, proposal, budget, or piece of work. Depending on the situation, you can say “thank you for approving this,” “I appreciate your approval,” or “thank you for giving us the go-ahead.”
Match the Thanks to the Type of Approval
- Thank you for approving this
- I appreciate your approval
- Thank you for your authorisation
- Thank you for giving us the go-ahead
- I appreciate you signing this off
- Thank you for confirming your approval
- Many thanks for approving the request
- Thank you for supporting the proposal
- I’m grateful for your approval
- Thank you for the green light
- Thanks for signing off on this
- Thank you for enabling us to proceed
Thank you for approving this
Direct and natural when the subject of the approval is already clear.
Example: Thank you for approving this. We’ll begin the work on Monday.
I appreciate your approval
A slightly more formal expression of gratitude for an authorised request or proposal.
Example: I appreciate your approval of the revised budget.
Thank you for your authorisation
Formal wording when the decision specifically grants authority to proceed.
Example: Thank you for your authorisation to release the funds.
Thank you for giving us the go-ahead
Friendly and natural when approval means the team can now proceed.
Example: Thank you for giving us the go-ahead on the pilot.
I appreciate you signing this off
Common workplace wording for formal or internal sign-off.
Example: I appreciate you signing this off so quickly.
Thank you for confirming your approval
Useful when the important point is written or explicit confirmation.
Example: Thank you for confirming your approval by email.
Many thanks for approving the request
Warm but still professional, particularly in British business correspondence.
Example: Many thanks for approving the request at short notice.
Thank you for supporting the proposal
Best when the person has endorsed the proposal, though support is not always the same as formal approval.
Example: Thank you for supporting the proposal at yesterday’s meeting.
I’m grateful for your approval
More personal and emphatic than a routine “thank you.”
Example: I’m grateful for your approval and the trust you’ve placed in the team.
Thank you for the green light
Informal and idiomatic, suitable for familiar colleagues.
Example: Thank you for the green light—we’ll start testing tomorrow.
Thanks for signing off on this
Concise and informal-professional for internal workplace communication.
Example: Thanks for signing off on this before the deadline.
Thank you for enabling us to proceed
Formal wording that focuses on what the approval now allows to happen.
Example: Thank you for enabling us to proceed with the next stage.
Approval, Support, and Acknowledgement Are Different
Use “approval” or “authorisation” only when the person actually had authority to approve something. “Thank you for supporting the proposal” is not equivalent if the person merely expressed support.
A useful follow-up often combines thanks with the next step: “Thank you for approving the budget. We’ll place the order today.”
