Your software
My Mautic version is: 2.16.3
My PHP version is: 5.6.29

Your problem
My problem is: I setup an account with SparkPost and I entered in my APKI key, I get a Success response when I test the connection, however, when I click on the Send test email button I don’t receive anything.

1. Do I need to run any Mautic cron job for the email to send?
2. Also, what email address is the test email being sent to? It doesn’t let me specify where I want to send the test email to.

Thank you!
