Currently our platform can integrate MailChimp to do a newsletter or email capture for you. Don't worry, you can use MailChimp for free :) They allow up to 2,000 subscribers and 12,000 emails per month. Once you have a MailChimp go here to set it up on your website!
You can also use Sendgrid for email captures if you prefer.
If you have any questions or feedback feel free to reach out to firstname.lastname@example.org. Thanks!
