When someone fills up the survey, do they automatically receive a copy if there’s an email field included?

I noticed email notifications consume credits. Does that mean every time a survey is submitted and I send a thank-you email, 1 credit is deducted per submission? So eventually I’ll need to top up once the plan credits are used up?

Can you clarify the full flow — from the respondent’s side, what exactly do they receive after submitting?

How do I calculate unique results based on their answers? For example, a personality test that categorizes them into a type, shows an explanation, and possibly includes further reading or an upsell/coaching offer?
