I'm spinning up a landing page where people can sign up for our newsletter. What are your favorite tools for email collection/management?

Formspark seems to be the leading open-source option and Formspree appears to be the defacto closed source(great UX).

Hi HN community, I'm building a web app where govt workers and citizens can interact with one another. If a citizen lives in a zipcode that the govt worker serves, they can interact.

It is important that neither group be impersonated. - How can I verify the identity of both groups? - How can I verify that the citizen lives in the zipcode they provided?

Any tools, libraries, methods, services are welcome!

Thank you in advance.
