Add X-MSYS-API header

[BigNoub]

Hello

I use Spark Post as an external SMTP. They have an option to track clicks and open emails, but they told me it needs to be activated by adding this line to the sender field:

X-MSYS-API: { “options” : { “open_tracking” : true, “click_tracking” : true } }

Like this:

From:<email@adress.com>
X-MSYS-API: { “options” : { “open_tracking” : true, “click_tracking” : true } }
Subject: Test Email

I tried to add this line to the “Sender email address” field in the Newsletter plugin but it’s not working (the plugin says invalid email address). How can I make this work?

Thanks

Anyone has an idea?
