Sendmail - add stuff in header

Sendmail - add stuff in header

  
Hi,

I need to add some json to the email-header
to be precise, I need to fill the X-SMTPAPI header
with

{ "category": "Example Category" }

is this possible?


Hi,

Have you tried using the HttpRequestHandler extension to add the header on the preparation of your email screen?

Cheers

Have you tried using the email extended properties?
yeah, the extended properties work fine.

should have thought of that before :)

thanks!
