The Leads tab is the record of every opt-in your campaigns have captured. It lives in your own database, in a table created when the plugin was installed.
Storage happens first, always:
Engage writes the lead to your site, and only then fires the delivery step that hands it to your autoresponder, your webhook and WP Sync. That order is deliberate. If the autoresponder is down, rate limiting or your key has expired, the subscriber is still yours and can be exported or re-added by hand. Losing a paid for lead to somebody else's outage is not acceptable.
What is stored with every lead:
- Email, first name, last name and phone, as far as the campaign asked for them
- The campaign that captured it and that campaign's type
- The page URL it was captured on
- The referrer
- Every UTM value present on the visit: source, medium, campaign, term and content
- The device: desktop, tablet or mobile
- The outcome of each delivery target
That source set is what lets you say which campaign, which page and which traffic source actually earned a subscriber.
The IP address is not stored by default. There is a setting to turn it on, and you should only do that if you have a lawful reason to keep it and say so in your privacy policy.
Exporting:
The Leads screen shows the 100 most recent opt-ins. Click Export all as CSV for the complete list. The file has one row per lead with the ID, date, email, first and last name, phone, campaign, campaign type, source, page, referrer, UTM source, UTM medium, UTM campaign and device. The export is streamed, so a very large list cannot exhaust your server's memory.
Your leads survive an uninstall and reinstall. They are only removed if you deliberately switch on Delete all Engage data when the plugin is deleted in Settings.
