Simple utility to check if an email address uses a free email provider.

This is useful if you want to rule out generic personal emails, like gmail, outlook, etc.

Create val
import { isFreeEmail } from "https://esm.town/v/stevekrouse/free-mail/main.ts";

await isFreeEmail("user@gmail.com"); // false (is free email)
await isFreeEmail("user@company.com"); // true (not free email)

The list of free email domains is from Hubspot.
