Email Gate turns a coupon into a list-builder: the coupon is hidden behind a form until the visitor submits their email address. (Looking to email the coupon itself? That's Email Delivery.)
Per-coupon setup #
Coupons gain an Email tab in the editor:

- Email Feature — set it to Email Gate for this coupon.
The tab also holds the gate message, button text, placeholder, success message, access-email subject and custom body — plus a terms-consent checkbox (label + linked page) and a per-address send limit.
What visitors see #

The coupon is replaced by the form; submitting emails the visitor an access link that unlocks the coupon. The link is valid for 7 days, and a cookie keeps the coupon unlocked for 30. Editors and shop staff with coupon-edit rights bypass the gate so they can preview.
Site-wide settings #
Coupons → Options → Email manages everything shared with Email Delivery:

- Email Templates — the Gate Access (and Coupon Delivery) emails, editable in place.
- From address / name, a deliverability health panel (blacklist, SPF checks) and Send Test Email.
- Rate limiting per IP and per address, and logging with retention and GDPR anonymization options.
An Email Statistics box on each coupon tracks sends and failures. Troubleshooting lives in Email Gate troubleshooting; every setting is documented field-by-field in the email settings reference.
