FillKite – Contact Form Builder with Conditional Logic & Lead Inbox

Description

FillKite is a form builder that stays out of your way. Build a contact, quote, booking or survey form in a couple of minutes, put it on any page, and read every lead in an inbox made for following up. The form adds about 11 KB (gzipped) to the page, and only on pages that have a form.

A builder that feels like a design tool

• The builder opens full screen: fields on the left, your form in the middle, the field’s settings on the right.
• 29 field types: text, paragraph, email, phone, number, website, date, time, name, address, rating, dropdown, multi-select, country, radio buttons, checkboxes, image choices, slider, Net Promoter Score, Likert scale, checkbox grid, ranking, colour, formatted text, consent, heading, divider, HTML block and hidden value.
• Fields can be full, ¾, ⅔, ½, ⅓ or ¼ wide, with help text, a starting value, read-only fields, sizes and your own CSS classes.
• Undo and redo, keyboard shortcuts, and a live preview that uses your site’s real form styles on desktop and mobile.
• A built-in accessibility check flags missing labels, placeholders used as labels, unclear messages and hard-to-read colours while you build.
• A visual designer per form: button, text, field and border colours, rounded corners, spacing and a full-width button, with a contrast warning. No CSS needed.
• Start from a template or from scratch.

Logic you can read

Show or hide fields with rules written as sentences: If Budget is greater than 500, show Phone. No code and no maze of dropdowns. The same rules run in the visitor’s browser and again on your server, so hidden fields are never validated or stored.

A lead inbox, not a spreadsheet

• Every entry lands in an inbox with statuses: New, Read, Replied, Won and Spam.
• Lead quality: each new entry is marked High, Medium or Low quality (a real mailbox, a company or free address, a duplicate, the spam score, answers filled in), and the inbox can show the best leads first.
• Reply timer: see how long each lead has been waiting, your average first-reply time, and get a reminder when a lead waits too long.
• Star the ones that matter, add private notes, edit answers, and search everything.
• Filter by form, date and lead quality, act on many entries at once, and export to CSV, Excel or JSON.
• Download or print any entry as a PDF.
• Duplicate submissions from the same email are flagged, never lost.
• The forms list shows views, entries and conversion per form for the last 30 days (counted without cookies), and on which pages each form is used.

Switch from Contact Form 7 or WPForms in one click

FillKite reads your old forms, even when that plugin is switched off. It brings over fields, choices, required settings, notifications, auto-replies and thank-you messages, and tells you exactly what it could not bring and why. Then it can switch your pages to the new forms for you: you see every change first, and each page keeps a revision you can go back to. You can also move forms between sites as a file, and import past leads from a CSV file.

Emails that arrive

• Built-in SMTP: send the site’s email through your own mail server, with the password stored encrypted (or in wp-config.php) and a test-email button.
• A sender check tells you whether inboxes can trust your domain (SPF, DKIM and DMARC), with the fix in plain English.
• A daily self-test email warns you in WordPress before a lead is missed.
• Branded emails: your logo, brand colour and footer on every FillKite email.
• An admin notification out of the box; add up to ten per form. Merge tags for any answer, plus {all_fields}, {page_url}, {entry_url} and more.
• An auto-reply to the visitor, and a webhook for Zapier, Make or your own app, retried once if it fails.
• A weekly summary email: new entries per form, how many still wait for a reply, and how fast you replied.
• A delivery log with Sent / Failed views, so you can see what was sent and what failed.

Spam protection without puzzles

• A hidden honeypot and a time check stop most bots with no extra step for people.
• An explainable spam score, worked out on your own site with no cloud service: links, pasted or untyped messages, long text sent too fast, repeated messages, text in another script, spam phrases and capitals. Each Spam entry says why, and “Not spam” teaches the site.
• A per-visitor rate limit, disposable email blocking, and a check that the email’s domain can receive mail.
• Optional Akismet, Cloudflare Turnstile, hCaptcha or reCAPTCHA v3.

Marketing built in

• Add subscribers to Mailchimp or Brevo from any form, optionally only when the visitor ticks your consent box (Mailchimp also with double opt-in and tags).
• Records where each lead came from (UTM tags, referrer and landing page) without cookies, optionally on every page of the site.
• Fires the GA4 generate_lead and Meta Pixel Lead events when those tags are already on your site.
• A QR code for the page a form is on, as SVG or PNG, made in your browser.

Privacy and consent

• Consent receipts: each ticked consent box is saved with the exact wording, a version fingerprint, the time and page, sealed against later changes, and printable as proof.
• IP addresses are stored only as a hash, and entries can be deleted automatically after a number of days you choose, per form.
• Test mode lets you try a live form without saving entries or sending emails.

Works with your site

• A FillKite Form block for the block editor, with a live preview.
• A FillKite Form widget for Elementor with style controls that start from your kit’s global colours and fonts.
• The [fillkite id="123"] shortcode anywhere else, and any form can open in a popup from a button.
• WooCommerce: show a form in its own tab on a product page; entries and emails know the product.
• Uncanny Automator: the trigger “Someone submits a form”, with every answer as a token.
• Forms pick up your theme’s fonts and colours. In block themes the button uses your theme’s own button style; with Astra, Kadence or an Elementor kit it uses your brand colour.
• Team access: let any WordPress role build forms, answer entries, or both.
• WP-CLI commands to list forms and entries and export entries.

Built with care

• Accessible: real labels, errors announced to screen readers, full keyboard support in the builder, and tested with axe.
• Right-to-left languages and multisite networks are supported.
• No limits on forms or entries.

For developers

External services

FillKite does not contact any outside service unless you turn a feature on.

CAPTCHA (optional, off by default). When you choose a provider under FillKite → Settings → Spam protection and enter your keys, the provider’s script loads on pages with a form, and the visitor’s answer token and IP address are sent to the provider to check it when the form is submitted.

• Cloudflare Turnstile: Terms, Privacy policy
• hCaptcha: Terms, Privacy policy
• Google reCAPTCHA: Terms, Privacy policy

Mailchimp (optional, off by default). Only when you add a Mailchimp API key under FillKite → Settings → Email marketing and turn it on for a form: when that form is sent (and, if you ask for it, only when the visitor ticks the consent box), the visitor’s email address, first and last name and the tags you set are sent to Mailchimp (Intuit) to add or update the subscriber in the audience you chose. The key is also used to load your lists. Terms, Privacy policy

Brevo (optional, off by default). The same as Mailchimp, for a Brevo API key: the visitor’s email address and first and last name are sent to Brevo (api.brevo.com) to add the contact to the list you chose. Terms, Privacy policy

Webhooks (optional, off by default). When you add a webhook URL to a form, each new entry is sent to that address. You choose the address and its terms apply.

SMTP (optional, off by default). When you turn on FillKite → Settings → Email sending, the site’s emails are sent through the mail server you enter. You choose the server and its terms apply.

Akismet (optional, off by default). Only when the Akismet plugin is active and “Also check entries with Akismet” is on under FillKite → Settings → Spam protection: each entry’s name, email, text answers, IP address, browser and page are sent to Akismet (Automattic) to check for spam. Terms, Privacy policy

DNS lookups. The email domain check on an email field (off by default) and the sender check under Settings → Email ask your server’s DNS for the domain’s mail and TXT records. No form data leaves your server.

The disposable email list ships with the plugin and is never downloaded. QR codes are made in your browser.
