Guide to integrating Outgrow with HubSpot for seamless lead capture

If you’ve tried to capture leads with interactive content—think quizzes, calculators, or surveys—you’ve probably run into the hassle of getting that info into HubSpot without copy-pasting or letting things slip through the cracks. This guide is for marketers, sales teams, or anyone who needs leads from Outgrow to flow straight into HubSpot, with as little friction as possible.

I’ll walk you through the integration, flag what actually matters, and call out where things get ugly (so you don’t waste time). No fluff—just what works, what doesn’t, and how to keep it all running without babysitting.


Why bother integrating Outgrow with HubSpot?

If you’re already using Outgrow’s interactive tools, you know they’re good at grabbing attention and getting people to fill out forms. But if those leads just sit in Outgrow, you’re missing out—HubSpot is where you actually track, nurture, and convert those leads.

Integrating the two means: - No more manual exports/imports. Your leads land in HubSpot automatically. - Faster follow-up. HubSpot workflows can kick in right away. - Cleaner data. Less copy-paste means fewer mistakes. - Better segmentation. You can use quiz or calculator answers to trigger custom journeys.

But—let’s be clear—not every integration is flawless. Sometimes mapping fields or handling custom properties gets messy. I’ll flag those pain points as we go.


Step 1: Prep Your HubSpot Account

Before you start, make sure you have: - A HubSpot account with permissions to manage integrations. - Admin access (or at least marketing access) to the right Outgrow workspace. - A list of the fields you want to capture—especially any custom questions you’ve built into your Outgrow experience.

Pro tip: If you’re planning to use custom fields in HubSpot, set them up now. It’s a pain to backtrack after the integration.


Step 2: Set Up Your Lead Capture Content in Outgrow

You’ll need an Outgrow experience ready to go. This could be: - A calculator (“How much can you save?”) - A quiz (“Which product is right for you?”) - A survey or poll

Don’t obsess over perfection here. Just make sure: - You’ve added a lead capture form (email is required, other fields are up to you) - The form comes before the results—otherwise, people will skip it

What to ignore: Outgrow’s built-in analytics are fine for a quick snapshot, but they don’t hold a candle to what you get in HubSpot. Focus on capturing the right info, not tweaking Outgrow’s reporting.


Step 3: Connect Outgrow to HubSpot

Here’s where most people get tripped up, but it’s actually pretty painless if you know where to look.

  1. In Outgrow, go to your Experience’s dashboard.
  2. Click on Integrations (usually in the left sidebar).
  3. Find HubSpot in the list of integrations and click Connect.
  4. Log into your HubSpot account if prompted, and grant Outgrow the requested permissions.

A heads up: Outgrow wants access to your contacts and some basic account info. If you’re squeamish about permissions, double-check exactly what’s being shared—but in most cases, it’s standard stuff.


Step 4: Map Your Fields (Don’t Skip This!)

This is the single most important step. If you get it wrong, your data will be a mess—or not show up at all.

How to do it: - Outgrow will show you all the fields from your lead form (name, email, custom questions, etc.) - On the other side, you’ll see your HubSpot properties (standard and custom) - Map each Outgrow field to the correct HubSpot property

What works well:

  • Standard fields (email, name, phone) usually line up with no problems.
  • HubSpot custom properties, if you set them up ahead of time, show up here.

Where it gets ugly:

  • If you have complex question types (multiple choice, sliders, etc.), double-check how the data is formatted. Sometimes HubSpot properties expect plain text, but Outgrow sends arrays or codes.
  • If you skip mapping a field, it won’t show up in HubSpot—no warning, just gone.

Pro tip: Test your mapping with a few dummy submissions before you go live. It’s way easier to fix issues before real leads start piling in.


Step 5: Test the Integration (Seriously, Don’t Skip)

You’d be surprised how often integrations “work” but don’t actually send data the way you want.

  • Fill out your Outgrow experience as if you’re a lead—use a real email (not your main one).
  • Check HubSpot to see if a new contact was created.
  • Make sure all the mapped fields show up correctly.

If something’s missing: - Double-check your field mapping. - Make sure you’re looking at the right HubSpot property (sometimes they get buried). - Outgrow’s support is responsive, but don’t expect miracles—documentation can be a little thin on edge cases.


Step 6: Set Up HubSpot Workflows (Optional, But Worth It)

Once the leads are flowing, you can use HubSpot’s automation to follow up, segment, or notify your team.

Some ideas: - Auto-email new leads: Send a resource, a thank you, or a next step. - Assign leads: Route them to the right salesperson based on quiz answers. - Score leads: Use Outgrow responses to bump up a lead score if they hit certain criteria.

Don’t over-complicate this. Start with a basic workflow and tweak as you go. Most teams get into trouble by trying to automate everything at once.


Troubleshooting Common Problems

Even with a “seamless” integration, stuff can break or just not work as you’d expect. Here’s what to watch for:

  • Leads missing in HubSpot: Usually a field mapping issue, or your form isn’t actually requiring email.
  • Duplicate contacts: If people use the same email to fill out multiple Outgrow experiences, HubSpot merges or updates the record. This is normal, but can be confusing if you’re expecting one contact per submission.
  • Data formatting weirdness: If you see values like “Option 1, Option 2” instead of just “Option 2,” check how your Outgrow questions are configured.

What’s not worth stressing about: Minor formatting issues. As long as you’re capturing the right data, you can clean things up in HubSpot later.


What About Zapier and Third-Party Tools?

You’ll see advice online about using Zapier or other middleware to connect Outgrow and HubSpot. Honestly? If you can use the native integration (as described above), do it. It’s simpler, faster, and less likely to break.

Use Zapier only if: - You need to do something fancy—like send data to multiple platforms at once - The built-in integration doesn’t support a field or property you need

But for 99% of cases, native is the way to go.


Keeping It Running (And When to Revisit Your Setup)

  • Check your integration every few months. Outgrow and HubSpot both update their platforms, so stuff can break.
  • If you change your lead form or add new quiz questions, revisit field mapping.
  • Don’t rely on email notifications alone. Build a dashboard or report in HubSpot to actually see the leads coming in.

Final Thoughts: Don’t Overthink It

Integrating Outgrow with HubSpot is mostly straightforward if you follow the steps, map your fields carefully, and actually test the thing before sending real leads through. Don’t try to automate every edge case on day one. Get the basics working, see how it fits your workflow, and tweak as you go. You’ll save yourself a lot of headaches—and you’ll actually capture more leads in the process.
