In the most basic configuration, Mailtrap offers a central inbox which gathers emails sent via its service. Emails sent via the SMTP servers of Mailtrap are not relayed to the appropriate email-servers on the internet but instead stored in a central inbox where they can be browsed. You may choose any address for sender and recipient. Thus, every email will be displayed exactly the way it would have been sent, including the header which contains the sender and recipient fields and the body which includes the formatting / markup and content.
