I would like to email everyone who submitted a registration at once.

I would like to email everyone who submitted a registration at once can i push the contacts through to mail chimp or is there a way we can email everyone from jotform without having to do one at a time?

To be able to achieve that, you will have to use Mailchimp and here is how to do that: https://www.jotform.com/help/163-How-to-Integrate-with-MailChimp

So you can send mass emails to addresses that your users submitted through your form.

If you have any further questions please let us know.

Thank you!
