We are considering forcing users to double opt in before we allow them to login to our application. One thing I’m not sure about is the ability to resend the opt-in email a second time via the API, for users that just missed the email or never clicked on the link to opt-in. Is it possible to resend it via the API?
The double opt-in email feature with HubSpot gives you the ability to require that your email recipients confirm they want to receive email communication from you when filling out a form.
