4 Click "Test Your Integration", which should be successful.
5 Once test is completed, for "Select Actions", select the options you would like to receive a trigger for. Note that triggers will always delete the email from your database, so for example, you DO NOT want to receive
any triggers where emails have been sent ok, such as "Delivered".
