Can you get the log from Mautic?

When I clicked test the connection, did it work?

Try changing the “Service to send email” setting to test.

It show success, but in log I got error message “error message - Unauthorized”.

Hello @gustavokennedy I got it solved by updating the file “/vendor/sparkpost/sparkpost/lib/SparkPost/SparkPost.php”.
