Spam stops here. Filtered in-house, never sent to an AI vendor.
Your forms are mostly noise. We fix that.
Contact, quote request, sign-up, feedback: point any HTML form at FormSubmit. Spam is filtered out, and every real submission lands in the inbox you verified, in one digest every 12 hours with every submission attached as a spreadsheet. Instant notifications, intent scoring and replies that write themselves are coming with Pro.
Free plan, no card required. 300 submissions a month.

</form>How it works
Three steps, and one of them is changing an attribute
No SDK, no JavaScript, no rebuild. If your form works today, it works with us today.
01
Point your form at us
Change one attribute on a form you already have. No JavaScript required, and no rebuild — a plain HTML form works.
02
We filter out the spam
Bots, link-drops and SEO outreach are caught before they reach you, in many languages. Pro adds an intent score with a breakdown you can read.
03
You get the ones that matter
Every real submission lands in the inbox you verified: gathered into one email every 12 hours on the free plan, the moment it arrives on Pro. With Pro, it can also go straight into HubSpot, Slack, Zapier or Segment, or to your own system by signed webhook.
Features
Everything between the form and your inbox
Capture is the easy part. What happens in the next two seconds is the product.
Spam filtering on every plan
Bot submissions, link-drops and SEO outreach are filtered before they reach your inbox, in many languages, and a hidden honeypot field catches the bots that fill in everything.
Intent scoringPro · coming soon
A 0–100 score built from intent clarity, company fit, seniority and urgency — each one visible, so you can disagree with it.
Replies that send themselvesPro · coming soon
Above a score you set, the reply goes out on its own — in your tone, after a delay that leaves you time to stop it. Below it, you get a draft.
Delivered to a verified inbox
On the free plan, a digest every 12 hours with every submission attached as CSV and JSON. On Pro, each one the moment it arrives, with Reply-To set to the person who wrote in. Nothing is ever delivered to an address nobody confirmed.
Connect your stackPro · coming soon
Push scored submissions into HubSpot, Slack, Zapier or Segment — mapping your form's fields onto theirs, not just four standard ones.
Signed webhooksPro · coming soon
HMAC-signed, retried with backoff, and delivered only to endpoints that proved they wanted them. Every attempt is visible.
Intelligence · Pro, coming soon
A score you can argue with
Most lead scoring is a number with no reasoning attached, which makes it impossible to trust and impossible to correct. Ours shows its work.
Respond within 1 hour
It reads the whole message
"We're comparing you against Typeform before our March renewal" is a different enquiry from "pricing?", and no keyword list will ever tell them apart.
It knows what you sell
Company fit is measured against your business, described in your own words — not against a generic idea of a good lead. A clinic and a recruiter should not get the same scores.
It defers when it is unsure
Borderline submissions go to a review queue rather than being forced into a yes or no. A false positive costs you a customer, so we would rather ask.
Automation · Pro, coming soon
The good ones can answer themselves
Scoring tells you which enquiries matter. Automation means the best of them already have a reply in their inbox by the time you read yours.
A submission arrives and is scored
Spam is filtered out first. What is left gets an intent score with a breakdown.
A reply is written in your tone
From your own instructions and what the person actually asked — not a template with their name pasted in.
It sends, or it waits for you
Above your threshold it goes out on its own. Below it, it sits in the queue as a draft you can edit.
You can stop it before it goes
The delay you set is a window to dismiss anything you would rather send yourself.
Auto-send when
score is 80 or above, it is not spam, and 15 minutes have passed
Everything below that threshold waits in a queue as a draft.
The delay is the safety net
Nothing goes out the instant it is written. Dismiss a reply during the delay and it never sends — and we re-check that at send time, not at the moment it was queued.
It replies as you
Your tone and your instructions, with Reply-To pointing at your inbox — so when they answer, the thread lands where you would expect it.
It chases the ones who left
Someone who typed their email and never submitted gets a recovery message — and does not, if they come back and finish.
Spam
Written by a machine, caught by a machine
Form spam stopped being misspelled pill adverts a decade ago. It is now fluent agency outreach, in whatever language you publish in.
Every language
Keyword filters are usually written in English, so non-English spam walks straight through them. Ours is built for spam in the languages people actually send it in.
It tells you why
Every verdict comes with a reason in plain words. When we get one wrong, you can mark it straight from the notification email.
No third-party AI
Filtering runs on our own servers. Your submissions are never sent to an outside AI provider to be classified.
