I really like this. A couple of random ideas: * Test integrations with various CRM type systems. Hubspot, Salesforce, Mailchimp all have huge ecosystems that you can leverage! * Offer per page configuration (on/off) * Expose CSS for easy skinning. This could be a text box on your portal. * Offer configurable fields to be collected * Implement a "send to your webmaster" button. * Expose that you are a whitelisted sender (if you are) Good luck!
