smartEngin Forms is a lightweight contact form plugin. Build as many forms as you like by clicking them together, style them without code and embed them with a shortcode. The interface follows your WordPress language; English and German are bundled, and more languages can be added through translation packs.
Features
- Drag-and-drop form builder: text, email, phone, number, date/time, choice fields (dropdown/multi-select/radio/checkbox), file upload, first & last name, GDPR consent and more.
- Preconfigured quick fields (salutation, subject, budget, message and more).
- Design without code: colours, spacing, radius and shadows via sliders and colour pickers, plus an optional two-part “hero card” with content widgets.
- Delivery to multiple recipients, reply-to and subject placeholders.
- Confirmation email to the sender with its own block editor and field placeholders.
- Automatic spam protection: nonce (CSRF), honeypot, timestamp check, per-IP rate limit and block lists (emails/words/IPs).
- Optional captcha: Cloudflare Turnstile (recommended), hCaptcha or Google reCAPTCHA v2 – enabled per form, invisible mode supported.
- Newsletter opt-in: forward a subscription to an external service (Brevo, Mailchimp or MailerLite) – only when the visitor ticks the newsletter consent box. Every transfer records its result (“Sent” / “Failed” including the service’s error message), so a failed transfer stays visible and can be retried from the admin area.
- File uploads with type, size and count limits and a protected storage location.
- Submissions are stored, viewable in the admin area and removed automatically after a configurable retention period (including their upload files).
- GDPR: configurable retention periods, separate consents, no external scripts unless explicitly enabled.
- Deliverability: emails are sent as multipart (HTML + plain text), based on
wp_mail()(compatible with SMTP plugins).
External services
This plugin loads no external scripts on its own. Only when you enable a captcha in a form does it load the script of the provider you selected and transmit the visitor’s IP address to that service for verification:
- Cloudflare Turnstile – script
challenges.cloudflare.com, verification viachallenges.cloudflare.com/turnstile/v0/siteverify. Privacy policy: https://www.cloudflare.com/privacypolicy/ - hCaptcha – script
js.hcaptcha.com, verification viahcaptcha.com/siteverify. Privacy policy: https://www.hcaptcha.com/privacy - Google reCAPTCHA v2 – script
google.com/recaptcha, verification viagoogle.com/recaptcha/api/siteverify. Privacy policy: https://policies.google.com/privacy
Add the provider you enable to your site’s privacy policy.
If you connect a newsletter service under “Newsletter” and enable it for a form, the submitted email address (and, if present, the name) is sent to that service to create/update a contact – but only when the visitor ticks the newsletter consent box:
- Brevo – contact sent to
api.brevo.com/v3/contacts; lists loaded fromapi.brevo.com/v3/contacts/lists. Privacy policy: https://www.brevo.com/legal/privacypolicy/ - Mailchimp – contact sent to
<dc>.api.mailchimp.com/3.0/lists/…/members; audiences loaded from<dc>.api.mailchimp.com/3.0/lists. Privacy policy: https://www.intuit.com/privacy/statement/ - MailerLite – subscriber sent to
connect.mailerlite.com/api/subscribers; groups loaded fromconnect.mailerlite.com/api/groups. Privacy policy: https://www.mailerlite.com/legal/privacy-policy
No newsletter data is sent unless you configure a provider, enable it for a form and the visitor consents. Add the provider you use to your privacy policy and data-processing records.
