How can I verify if Platform Email is set up correctly for my environment?

In the Cloud Platform user interface, navigate to Environment > Logs > Download fpm error log.

Cloud Platform displays the following message when emails are successfully sent using Platform Email:

MessageId=******* and Status=SUCCESS

INFO: MessageId=010001808415ee36-d53c6626-dd24-4611-96d6-23c47fe7ee19-000000, EnvUuid=ac7bfece-3a11-4426-ac58-ec9249fc5291, ClientId=56a3b7c4-a9fe-4b08-9e3e-d7836bfeab2d, Status=SUCCESS, To=7c1668dd0b7cc141ae8d5461a3c8f42f733efac1, From=f409dc0d8f70691b42742955e1fd9ee088fbc3d7

Additionally, the recipient of your email can inspect the headers of the email and verify that the Message ID contains amazonses, such as <random-uuid>@email.amazonses.com.
