Why Sobi Forms?

  • Lightweight — ~5 KB CSS + JS on form pages (gzipped); assets load only where a form is rendered
  • No bloat — no jQuery, no front-end React, no Bootstrap on the public site
  • Native SMTP — route notification and confirmation emails through your mail server
  • Custom notification emails — edit admin and visitor subject/body per form with placeholders ({{field.*}}, {{all_fields}}, and more)
  • Native webhooks — POST JSON to Zapier, Make, n8n, or any HTTPS endpoint
  • Brevo & Mailchimp — sync signups to Brevo lists or Mailchimp audiences from any form; map fields, optional double opt-in, delivery logs with Retry
  • Gmail-style submissions inbox — read, star, filter, search, spam queue, and Trashed tab; split list + detail layout to manage every contact form submission in one place
  • File uploads — secure private storage; admin-only downloads
  • AJAX contact forms — submit without a full page reload
  • GDPR-friendly — inbox-only delivery, hashed IP, no tracking pixels
  • Spam protection — honeypot, nonces, rate limit, optional Turnstile and Akismet
  • Fast admin — drag and drop form builder (React in admin only)

File Upload Forms

Collect resumes, PDFs, and images on the same form as the rest of your fields — no extra plugin. You pick what to accept; files stay private on your server and download only from the admin inbox.

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.<field_id>}}, 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.
