HubSpot forms: free on every plan, with three walls you find later

Forms work on the free tier. Raw HTML markup, campaign association and conditional redirects don't — and each sits behind a different subscription.

Forms are one of the few things HubSpot gives away without asterisks. Every plan, including free, can build and publish them.

The asterisks are elsewhere, and they’re the kind you meet after the form is already embedded on a client’s site.

What you get on every plan

A form builder, embedded forms for any site, standalone forms with a share link, and submissions landing straight in the CRM as contacts. Progressive fields and dependent fields — the ones that change what’s asked based on previous answers — are documented without a tier restriction.

For most small operations that’s genuinely the whole job, and it costs nothing.

The three walls

1. Raw HTML forms need Professional

This is the one that catches developers.

If you want to write the form markup yourself — your own classes, your own layout, your own validation, styled to match a site you built — that’s a Marketing Hub or Content Hub Professional feature.

On free and Starter you embed HubSpot’s own markup and style around it. You can reach it with CSS, but you don’t own the structure, and it isn’t yours to change.

For a developer this is the difference between a form that looks native and a form that looks embedded. It’s usually discovered at the exact moment someone asks why the form doesn’t match the rest of the page.

2. Campaign association needs Marketing Hub Professional

Attaching a form to a campaign — so submissions roll up into campaign reporting — is Professional and above.

Practical consequence: on a lower tier you can collect submissions perfectly well, but attributing them to a specific campaign is manual. If reporting on which campaign produced which leads is the point of the exercise, that’s the tier you’re actually shopping for.

3. Conditional redirects need Enterprise

Sending different people to different destinations based on what they answered — a meeting scheduler for one answer, a page for another — requires Sales or Service Hub Enterprise.

The lower-tier version is one thank-you destination for everyone, and branching handled after the fact.

And the two from the free tier itself

Neither is about forms specifically, but both land on them.

One automated email per form. Someone submits, they get exactly one automatic reply. A sequence isn’t available — that’s workflows, which are Professional and above. So a form on the free plan collects well and follows up once.

HubSpot branding, not removable. It appears on free forms and landing pages, and there’s no setting to turn it off. For an internal form, irrelevant. On a client-facing page with your name on it, this is usually the limit that decides the tier for you, regardless of the other three.

What I’d check before embedding one anywhere

Where the submission actually lands. A form is a write path into your CRM, and every write path deserves the question: what happens when it fails? Test a submission with a broken field and see whether you’re told, or whether it just doesn’t appear.

What the embed loads. An embedded form is third-party script on your page. If you run a Content Security Policy — and you should — the form’s domain has to be allowed explicitly, or it silently won’t render. That failure looks like an empty div, not an error.

Whether you need the form to be yours. If the answer is yes, you’re on Professional. Deciding that before you build the page is much cheaper than deciding it after.

The follow-up ceiling. One automatic email is a real constraint on a lead capture form. Plan the second and third touch as a manual task, or plan the tier that automates it.

The pattern, again

Forms are free. What isn’t free is control — over the markup, over the reporting, over where people go next.

That’s the same shape as everything else in the free tier: the thing itself is generous, and the parts that make it yours are the parts you pay for. Knowing which of those three you actually need is the whole decision.
