If your app needs to send emails to its users, you need an email database. Your database needs to store the emails that your app is going to send and store the replies to those emails so that your app can present the users with a coherent conversation history to each email. The most basic database for this would be a plain old relational database (SQLite is great for this purpose), but you can go deeper than that to build something more powerful. For example, you can build an index-based database to improve performance or build a document-oriented database to store each email as a document.
