Has anyone successfully switched off Engagement Tracking on SparkPost?
I did this at https://app.sparkpost.com/account/smtp
But all links are getting converted to http://go.sparkpostmail.com/
'options' => [ 'sandbox' => false, "open_tracking" => false, "click_tracking" => false ],

3Thanks for providing your answer. Can you please provide some more instructions and an explanation of what this line of code means, where it goes, and why it helps? – Christia Nov 18 '17 at 7:33
