I just found a solution to what I have been pondering for some time now, and I wanted to share this with anyone who might benefit from this solution -not enough seem to be out there yet 
I love GetResponse for its email list management and pretty robust auto-responders. I personally use it and highly recommend it to my clients as well, but the issue I ran into was that you’ll get a “Page Not Found” error when you redirect subscribers to land on a confirmation or thank you page you created within WordPress.
I suspected the cause to be associated with redirect, but I couldn’t figure this out.
However, I finally found a simple workaround that gets the job done. Here’s now:
- Create a HTML page like www.example.com/processing.html
- And redirect to your wordpress page in your .htaccess file like this below
Redirect 301 /processing.html http://www.example.com/thank-you-for-your-subscription/
- Make sure to change the value for “confirmation_url” hidden element on your HTML and mission accomplished!
Not sure how long this will be up, but here’s the page to the wordpress forum where I got this idea from:

That’s it -thanks!

Thanks for the help. I’m having the exact same problem and is really anoying. Did you report it to get response by any chance?
I’m glad it helped! Good point about reporting the issue – I just haven’t done so since I wasn’t certain if the issue was applicable to everyone.
Also, small correction… you can skip the Step 1 above (you don’t have to create a physical file).
Thanks!

This is not really a solution its a work around. I was having the same issue and had to settle for this same method too. Man what an annoying error.
