Because he knew her power was much greater than Cora and Regina, Rumple wrote that letter to Cora. Now the weird thing is that Rumple only knew Zelena before she was fully green and owned a pendant. In fact if he knew her after she had her pendant, he would have tried to grab it for himself to make himself more powerful. I still wonder when Rumple and Cora fought. Because for the longest time, she was in Wonderland, until 2.09 when she came back to EF with Hook. Maybe it happened beforehand or in a private place.
