I followed the following guide to setup an AWS Pinpoint project:
https://docs.aws.amazon.com/pinpoint/latest/userguide/gettingstarted-create-campaign.html
After I launch the campaign, the email is not sent (I chose 'immediately'). So, I checked 'Test messaging'. It also failed to send mail. I had already activated my sender email address.
The campaign analytics says:
Messages sent - 1
Messages delivered - 1
Delivery rate - 100%
Email open rate - 0%
Bounce rate - 0%
May I know why the mails are not delivered by AWS Pinpoint please?
