So, all e-mails are captured by Mailtrap and can be viewed only by its web interface?

Not exactly. You're not required to stick with our web interface; it is possible to forward every single e-mail to your mailbox or your teammates' ones. You can even enable automatic forwarding and Mailtrap will act as a proxy between your application and your e-mail client software, so you won't miss important messages from the QA environment like exception notifications.
