Do you want to send a thank you letter to that helpful farmer? It’s easy.
Whenever a farmer helps you, either by filling a crate or reviving a tree, an envelope will appear at your end, attached to the farmer’s avatar icon.
If you click once on the envelope for crates and double click for trees, you will automatically send them a thank you letter, which may or may not contain a gift card. Remember that you have limited time to send a thank you letter after you have received help.
