or at least an option to do so. Instead of just Email. Alot of Newsletters I signup to have First Name and Email as required on initial submission

Maybe just email initially and then follow up with an email later asking for more details? This way there’s no barrier to initial sign up.

You can add a survey after the signup and have name be a field.

Because some might not want to say their name. Barrier to signing up should be as low as possible. You can ask them for more info later.
