Most Email Gate problems come down to one of four things: the gate showing coupon content instead of the form, access emails not arriving, expired access links, or cookies not sticking. Work through the section that matches your symptom.
The coupon shows instead of the gate form. Confirm Email Gate is enabled globally under Coupons > Options > Add-ons, and that the individual coupon has Email Gate turned on in its Email settings. Note that anyone who can edit coupons (administrators and editors) bypasses the gate automatically, so test while logged out or in a private window. If you use a caching plugin, clear the cache after enabling the gate. Gated coupons are also hidden from coupon loops by default — enable Show in Loop under Coupons > Options > Display if you need them listed there.
Visitors don't receive the access email. Check your sending setup under Coupons > Options > Email and run the Deliverability Health Check, then use the Send Test Email tool to confirm mail leaves the site. If mail is unreliable, install an authenticated SMTP plugin such as WP Mail SMTP. Also confirm the visitor hasn't hit a rate limit (by default 5 emails per IP and 3 per email address per hour) and check their spam folder. Individual coupons can also set a per-address send limit. If logging is enabled, review the email logs for the attempt.
"Link no longer valid" / expired link. Access tokens expire after 7 days by default. The visitor just needs to resubmit the gate form on the coupon page to get a fresh link. You can raise the expiration per coupon in its Email Gate settings.
The form keeps reappearing after a visitor enters their email. Access is remembered with a cookie (prefixed cctor_gate_access_, 30-day default). It can fail to persist if the token expired while the cookie lived on, if the browser blocks or clears cookies, if the visitor is in private/incognito mode, or if a caching layer is serving a cached gate form. Exclude gated coupon pages from caching, or configure your cache to respect the cctor_gate_access_ cookies.
