I need a term to search for contact form Software as a Service (SaaS) provider
There is this service for website owners which is a both an email server (Backend as a Service) and a comfortable GUI for creating contact forms (Frontend as a Service).
Website owners who don't want to start dealing with Email DNS records in their infrastructures and with contact form add-on modules ("plugins") for their content management systems can rent the service of such service providers and get an (hopefully) well established and well venerated email server and a comfortable system to create contact forms;
The rest is just redirecting a visitor/potential-customer to such contact form via the main navigation menu (through a regular "Contact us" link) and after the form submission is complete the visitor/potential-customer would be redirected back to the original website.
What is the common term for such services? I didn't find many such service providers with "contact form outsourcing" and some similar terms.
