The backend for your Backendless app sends out emails for the following events:
The default email address used by Backendless is firstname.lastname@example.org, which is an automated account – we do not actively monitor incoming emails there. If you do not change the email address in your Backendless account and a user replies back to any of the emails listed above, the response goes back to the inbox for our automated account.
We see a lot of applications which are published to app stores where email address is not changed. As a result, you are missing direct communication received from your users. To avoid this, it is recommended to change the email address per the instructions in our documentation.
