Hi.

Can you get the [log from Mautic](https://docs.mautic.org/en/troubleshooting)?

When I clicked test the connection, did it work?

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

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

Thanks,
