I too would love DOI by form rather than (or in addition to) by page. We really want to only have our blog pages (hosted by Husbpot) and our newsletter subscription page have Double Opt In enabled, and everywhere else disabled, mostly because of the confirmation email it sends and how that will confuse people if for example they are filling out a form of ours to access a white paper…if they receive an email asking them to confirm their subscription just by filling out that white paper form page, it causes confusion.
Apparently there is also no way to choose blog pages (or better yet the blog domain as a whole) to add to the “Enable” list in the DOI settings, so if we choose to enable DOI only for our page that people fill out a form to subscribe for our mailings, then it is preventing DOI from working on any of the blog pages, and that’s not what we want.
It seems that DOI by form would solve this. Please consider!
