The example business is Halverson Cycle & Repair, a bike shop with a repair workshop in Portland, Oregon. The reply is the one the tool really gives.

}Use it when
People asked to hear from the business, in person or by email, and should be signed up.
What it does
Email each person a request to confirm their subscription: only those who press Confirm ever get an issue. For people who asked to hear from the business. Skips anyone already in, invited in the last day, unsubscribed or undeliverable. At most 20 invitations a day per account. Free: they go out through the business's own email service.
What comes back
invited: the people sent an invitation, skipped: the ones left out with the reason (already in, invited lately, unsubscribed, undeliverable), and invitations_left_today. Every reply also carries cost_usd and balance_usd.
