-
Document-light builder
Add fields, rows, and steps on a clean canvas—no cluttered panels.
-
True inbox
A Gmail-style workspace for every lead—not just email forwarding.
-
Super lightweight
~5 KB on form pages. Zero performance impact everywhere else.
A real submission inbox
More than email forwarding—a Gmail-style workspace for every lead, with views, exports, notes, and attachments.
Faster and lighter than the rest
Most form plugins ship a front-end pile-up. Sobi Forms does not—~5 KB when a form is on the page, zero impact everywhere else.
Privacy first, GDPR by design
You choose what leaves the site—and for how long it stays. Hashed IPs, auto-purge, WordPress personal data export & erasure, no telemetry to the plugin author.
Native SMTP routing
WordPress wp_mail often lands in spam or never arrives. Route notifications through your own SMTP so confirmations actually hit the inbox—with delivery logs and retry.
Hardcore spam prevention
Block fake leads without punishing real visitors. Honeypot, rate limits, optional Akismet and Turnstile—no CAPTCHA tax by default.
Webhooks, Brevo & Mailchimp
Unlimited HMAC-signed webhooks for Zapier, Make, or n8n—plus native Brevo and Mailchimp list sync. Field mapping, logs, and retry, free in core.
Conditional logic
Ask one question, then reveal only what matters next. Show only when… on any field—Match all or Match any.
Multi-column layout
Place up to three fields side by side. Drag to resize, double-click to equalize—and columns stack cleanly on mobile.
Multi-step forms
Split long forms into pages with Next, Back, and a progress bar. Per-step validation—one submission at the end.
