How To Use the Public Email Opt-In Form
Every Argenta subscription includes a public email opt-in form. People who find your website use it to join your email list, and each sign-up arrives in Argenta as a constituent who is already opted in to General Email Communications, so nobody on your team has to retype their details.

A published opt-in form, in the organization's own colors.
Everything for the form lives on one page: go to Our Public Interfaces > Public Email Form. That page holds the public link to your form, the code to embed it on your own website, and the Email Opt-In List of everyone who has signed up.
For the full walk-through, from what the form asks for to what happens when someone signs up and how to unsubscribe a person, read Public Form: Receive Email Sign-Up Form.
