In this paper, we propose a high capacity text steganography method using Huffman compression. The forward email platform is used to hide the secret data. We make use of the number of characters used in email id to indicate the hidden secret data bits. So, to make optimal utilization of number of characters in email ids, the characters added to the email id to indicate the secret data bits are taken from the processed secret data. Hence, the hiding capacity is further increased. The new characters are appended just before the `@' symbol of email ids. Experimental results show that our method performs better than the some important existing methods in terms of hiding capacity.
