How do I connect it?
- Open a campaign that has a form (or add a form input on Customize). Click the form → + Add integration.

- Mailchimp → Connect. Add new Mailchimp API (or pick one you already saved).

- In Mailchimp: profile → Account & billing → Extras → API keys → Create A Key. Name it, copy it.

- Paste the key in Popupsmart, Save.
- Details: pick the audience. Match fields: email at minimum, then name or whatever the form collects. Save.
Status defaults to on. Three-dot menu to pause it.
Mailchimp sends do not spend Popupsmart's email quota. That quota is for Popupsmart's own autoresponder. Pricing.
