Systems and methods for efficient electronic message storage and retrieval

One or more computing devices, systems, and/or methods for efficiently storing and retrieving electronic communication are provided. Messages with the same structure are grouped into a same cluster. A template is created for the cluster. The template is populated with constant values that are the same amongst the messages. Variable values that are different amongst the messages are stored within user account repositories for each message. In this way, the constant values are merely stored once for the messages within the cluster. A template within a general repository and variable values within a user account repository may be used to reconstruct a message.
