Mailtrap is a fake SMTP server for development teams to test, view and share emails sent from the development and staging environments without spamming real customers.
Now this is great for testing: use mailtrap’s SMTP server and all mail sent through it will not actually be sent to the end-user but get caught in one inbox you can view. That way you can safely use real e-mail addresses in developmment environments.
