Lightweight Contact Form vs Sobi Forms

This is the absolute lightest contact form for WordPress. This plugin is designed for the fastest pagespeed. So, there is no CSS stylesheet, no extra files, and no overhead. And no spam. It uses Google reCAPTCHA v3 so as not to annoy your users with any extra step, while keeping your contact form spam-free. If all you need is a simple contact form to take messages from site visitors, and fast page speed is your priority, this minimal plugin is for you. Although this form is lightweight and simple, it blocks SPAM, and has both client-side and server-side validation. This is a solid and dependable contact form. NOTE: To make use of the extra spam protection from Google reCAPTCHA v3, you must get your reCAPTCHA v3 API keys from Google. This is a free and easy step, and is strongly recommended. Features Emails are sent to the admin email which is set in your WordPress General Settings. Add the contact form to any page with a shortcode. Both JavaScript client-side and PHP server-side validation. It’s just one file. No extra CSS or JavaScript files. This is for the most lightweight footprint. You must add any CSS styling yourself. This is easy and is explained in the installation guide. (In addition, if you need extra fields or different forms for different pages, see the Advanced: Add Custom Form Fields section.)

Drag and Drop Form Builder Canvas on the left, settings on the right — build a form in minutes and save without a page reload. Start from templates (Contact, Quote, Job, Event, Support). Put fields side by side (First name | Last name). Mark each multi-checkbox option Required or Optional — mandatory terms, optional newsletter. Add inline links in paragraphs and consent checkboxes. Pause a form, close it on a date, or stop after N submissions. Text, email, phone, date, file upload, consent checkbox, and more — all in one builder. Native SMTP Stop fighting WordPress mail. Route admin notifications and visitor thank-yous through your SMTP server — configure once under Sobi Forms → Settings, test the connection, and retry failed sends from the logs. No third-party form SaaS in the middle. Custom notification emails Customize admin notification and visitor confirmation emails per form — subject and HTML body — under After submit in the builder. Open an email action → Content tab. Leave fields blank to keep the default template (existing forms unchanged until you edit). Placeholders: {{form.title}}, {{form.slug}}, {{submission.id}}, {{meta.source_page}}, {{field. }}, and {{all_fields}} (full field list). Use + Var to insert tokens. Send test email delivers a preview to your WordPress account address only — never to form recipients. Webhooks Connect Sobi Forms to Zapier, Make, n8n, or any HTTPS endpoint. Add unlimited webhook URLs per form under Automations in the builder; submissions POST as JSON in the background. Failed deliveries land in the logs with Retry — no extra connector plugin. Brevo & Mailchimp Sync newsletter and lead-capture signups to Brevo or Mailchimp without a separate connector plugin. Add your API key under Settings → Integrations, then + Brevo or + Mailchimp on any form: pick list/audience, map the email field and custom attributes or merge fields, optionally enable Require double opt-in. Skipped, warning, and failed API runs appear in each connector’s Logs tab with Retry. Submissions Inbox Manage every lead like email: read/unread, star, search, filter, spam queue, and Trashed with restore. Split list + detail, admin notes, and a dashboard widget for unread submissions. See which page a submission came from. Export to CSV or JSON when you need a report or backup. Embed Anywhere Shortcode or Gutenberg block — one click to Embed, paste on any page. Works with Elementor, Divi, WooCommerce, and any builder that supports shortcodes or blocks. ~5 KB on pages with a form; zero weight everywhere else. Security & Privacy Honeypot, nonces, and server-side validation on every submission. Optional Akismet and Cloudflare Turnstile. Rate limiting against abuse. Data stays on your server — no tracking pixels, inbox-only mode when you want zero email. Privacy Policy Sobi Forms processes data submitted through your forms. Per form you choose how submissions are delivered: Email notifications – when the admin notification action is enabled with valid recipient addresses, field values are sent via wp_mail() or SMTP. Custom subject/body templates (when configured) are resolved with placeholders at send time. Visitor confirmation – when Send user confirmation is enabled under After submit, the submitter may receive a thank-you email at the address from the selected email field. Custom templates may include their own submitted field values via placeholders; the default template is a simple thank-you without field values. Database storage – when Save to inbox is enabled (default for new forms), submissions are saved in custom tables on your site (wp_sobiforms_submissions, wp_sobiforms_forms). Retention / auto-purge is configured on that action. You can use inbox-only delivery with no email. Hashed IP – when storage is enabled, a one-way SHA-256 hash of the visitor IP is stored with each submission for abuse prevention. Raw IP addresses are not stored. Rate limiting – configurable under Settings → Spam protection (default 10 submissions per hashed IP per hour; set to 0 to disable). Transients expire automatically. Admin notes – internal notes on submissions are stored in your database and never shown on the front-end or included in emails. No tracking – Sobi Forms does not connect to third-party analytics or advertising when processing form submissions. Optional Akismet – if you enable Akismet spam filtering under Settings → Spam protection and the Akismet plugin is active, submission content may be sent to Akismet’s service for spam checks. Optional Cloudflare Turnstile – if you enable Turnstile under Settings → Spam protection, the browser loads Cloudflare’s Turnstile script and may send a verification token to Cloudflare when a form is submitted. Optional Webhooks – if you add Trigger webhook under After submit, submission data (and file URLs when applicable) are POSTed to the URL you provide. Optional Brevo – if you add an API key under Settings → Integrations → Brevo and add a Brevo automation on a form, the visitor email and mapped field values are sent to Brevo’s API (api.brevo.com) to create or update a contact in the list you select. Brevo is a third-party processor; review Brevo’s terms and your lawful basis for list signup. Optional Mailchimp – if you add an API key under Settings → Integrations → Mailchimp and add a Mailchimp automation on a form, the visitor email and mapped merge fields are sent to Mailchimp’s Marketing API (*.api.mailchimp.com) to create or update an audience member. Mailchimp is a third-party processor; review Mailchimp’s terms and your lawful basis for list signup. No data sent to the plugin author – form submissions stay on your server and mail server. The Feedback settings tab links to the WordPress.org support forum and sobiforms.com/roadmap only if you choose to open them. Site owners are responsible for their privacy policy and lawful basis for collecting visitor data.
