Is there any possibility to use DEManager without facing CORS issues? Something like whitelisting the domains for our external websites?


You can just update the form action URL to start with https:


You can also use the base SFMCs URLs with https in other places to work around CORS -- like landing pages:


  • Hi Adam, thanks for your response. We have the https: in our HTML, which is placed on the website of our client so we can't change the url to pages.exacttarget. Is there another solution u know of? Jan 9 '18 at 14:39
  • You can purchase an SSL cert through SFMC and have them apply it to the domain in question. Jan 9 '18 at 16:28
