Electronic mail or email is among the most popular data or message carrier. One of its powerful features is the sent message history records which have a long lifetime without big memory devices. However, with those technology advancements, the security aspects have become a serious concern. The ease of access to the networks has made an exposed leakage for some irresponsible parties who have the competencies to steal the information while the delivery streams take place. The email user is advised to add another security act such as encrypting toward the email contents before it being sent using ESP service. In this paper AES and 3DES cryptography method successfully implemented to securing email text messages. Email message being encrypted first using both algorithms, and then being evaluated and analyzed from various aspects. Evaluation's results shows that AES is better in terms of compile time, while 3DES is better in terms of increasing message's size after the encryption process, but the change in the addition of bytes is not significant. So based on the results of tests, email users are recommended to use AES encryption.
