⚠️ Disadvantages of Saying “Thank You for Your Cooperation”
1. May Sound Robotic or Impersonal

Better Alternative: Use “I appreciate your help” for a more human tone.
Example: Instead of “Thank you for your cooperation,” try “Thanks so much for jumping in to assist.”

Better Alternative: Try “We’d be grateful for your support” to sound more inviting.
Example: “Thank you for your cooperation” → “We appreciate your willingness to assist.”
