Monitor when a user changes their email address in your C application

Most of the time, when building a C application that is served to users, you will need to store the user's email address in your database. There are multiple reasons for this, such as sending the user a welcome email when they sign up for your application, sending the user a password reset email when they request a password reset, or sending the user a notification when they have been mentioned in a comment. In addition, it is commonly used for user authentication and authorization.

In most cases, some users may want to change their email addresses for various reasons while using your application. For example, they may have mistyped their email address when they signed up for your application or changed their email address for personal reasons. In any case, it is essential to track when a user changes their email address in your C application to ensure that you are always aware of the change and can update your database accordingly.

Fortunately, here at LogSnag, we have created a powerful solution for this problem. At its core, logSnag is a powerful, real-time event tracking tool that works seamlessly with any C application. LogSnag makes it easy to track any important event in your C application and monitor things such as user activity, user journeys, and more.

One common use case for LogSnag is to set up event tracking for when users change their email addresses in your C application in real-time. You may also optionally set up rules to notify you and your team when a user changes their email address in your C application.

In addition, LogSnag allows you to track user journeys and create a timeline of their actions to monitor the users' email address history and any other activity they have done in your application. This way, you can always track the activity of a specific user, such as when they change their email address and any other activity they have done in your application.
