So far I love Campaign Monitor. Thanks for this excellent, well-designed product.
Currently I am finding that the only required field in the default subscription form is the email address.
2. Is there a way to have a custom error page so that the subscriber doesn't feel he/she has left the site?
The API option would allow you to easily show your own custom error page if there is a problem with what your subscriber submits.
Thanks for the quick reply, Dave. I can see you are way smarter than me so wish me luck! :-)
