Suitable messages for thank you notes will depend largely on the context and nature of the thanks being given. However, some general thank you messages include "I'm humbled and grateful," "You're the best," "I'm touched beyond words" and "You're a blessing to me." It is recommended by Hallmark to send such thank you messages as soon as possible and some good closings for a thank you note include "Warmly," "Feeling spoiled," "With gratitude," "Love and thanks" and the more energetic "ThankyouThankyouThankyou."
Hallmark offers examples of thank you messages for more specific situations, such as the receipt of a gift or some kind of assistance.
When writing a thank you note for a gift, some things to include are a specific reference to what the gift was, along with what made it so special, and an indication of how it will be of use. For example, a good thank you message for a tie might be: "Thank you for the exquisite tie. It's exactly what I needed for my upcoming job interview."
Good thank you messages for assistance received include "This has been a challenging time, and I appreciate you so much," "You have no idea how much your help has meant," "I can never thank you enough, but this is a start" and "You are always so helpful."
