How to Enrich HubSpot Data With Hunter

Imagine your HubSpot account – the lifeblood of your business operations, the cornerstone of efficient client management – filled with inaccurate contact information.

If the data is lacking or incorrect in some manner, it will cause difficulties for everyone, from your marketers to your support heroes.

Unfortunately, it’s too often the case that contact information in HubSpot isn’t reviewed and gets stale.

This is where the integration of your HubSpot account with comes into play. It ensures the instant transfer of contact details from Hunter to your HubSpot contacts, boosting your sales efficiency and streamlining your sales and marketing processes.

  • Seamless sync and lead transfer: Effortlessly transfer your contacts and leads from to HubSpot, complete with details like names, email addresses, job titles, and more.
  • Lead verification: Export contact information from HubSpot to Hunter to validate email addresses, ensuring your leads are up to date and reducing email bounce rates.
  • No more manual entry: Copy-pasting data directly to HubSpot is time-consuming and prone to manual errors. Hunter’s HubSpot integration automates the process without breaking your workflows.

This article will explore the advantages of integrating with HubSpot, outline the necessary requirements, and walk you through the integration process using real-world examples.

Understanding the value of data enrichment

Before we dive into the nitty-gritty of the integration, let's address why enriched data matters in the first place.

Why does enriched data matter?

Well, let's say that clean data is better than outdated data.

Having confidence in the accuracy and freshness of your HubSpot data means no more awkward moments searching for a prospect's job title or reaching out to contacts who've left their target company—no one needs those email bounces as this hurts your email domain reputation.

Moreover, data enrichment is more than just cleaning your CRM; it enables targeted marketing efforts, connects you with high-value customers, and optimizes marketing costs.

Thanks to the integration, your HubSpot database remains clean, complete, and consistent. This means your teams can focus on their core roles without the hassle of data collection and verification.

Now that you understand why enriched data is vital, let’s cover how to set up the integration and provide an overview of HubSpot.

Setting up the integration

Hunter offers a free HubSpot integration that allows adding new and already saved leads from Hunter to your HubSpot account.

You’ll need:

Connect HubSpot to Hunter

To start the integration, go to the Integrations page, and select Connect HubSpot.

You will see two options, based on whether you already have a HubSpot account or not.

  • Create a new HubSpot account
  • Sign in to your HubSpot account

If you already have an account, click the Sign in to your HubSpot account button and follow the steps.

You'll automatically be prompted to enter your HubSpot credentials and log in to authorize the integration. This step establishes the connection between and your HubSpot account.

Select Hunter as the account and Choose Account.

After authorization, you'll find "HubSpot" in Hunter's "Integrations" sidebar menu. That’s where you can review and update the settings.

Set up the synchronization

The next step is to review and adjust the settings to customize the integration according to your specific needs.

There are several options available to configure your synchronization between and HubSpot:

  1. You can configure whether you want leads to be updated in HubSpot when they are updated in Hunter and/or deleted from Hunter. This will ensure that any changes to your leads on Hunter will automatically be updated on your CRM.
  2. You can also select when a lead should be created in HubSpot:
  • when you create a lead in Hunter,
  • when an email is sent from Hunter Campaigns to the lead,
  • or opt to do this sync manually.
Options for how leads are synchronized with Hunter


  • Only the leads you personally create will sync. If your colleagues in your Hunter team save leads, those won't automatically sync to your HubSpot account.
  • When you opt for a manual synchronization and click on a lead, a button will appear under ''Synchronization''. Click on ''Sync this lead'' to manually update it in HubSpot.

If you already had existing leads saved in Hunter before connecting Hunter with HubSpot, those leads won't be synchronized by default. However, you can synchronize them in HubSpot by clicking the ''Synchronize X leads'' button on the integration's settings page. This also happens when you select the option to sync leads manually, as it allows you to sync leads in bulk.

Your synchronized leads can have a dedicated Contact Owner in HubSpot. To enable that option, select the assigned person from your team:

It's also possible to create a deal in HubSpot every time a lead is created in Hunter by selecting the appropriate box.

You can map different Hunter attributes to properties in HubSpot. This will ensure the integration automatically synchronizes your data from Hunter to HubSpot based on this mapping and manage leads better with a more accurate database.

To sync attributes, they would need to be on the Contact level. The associated HubSpot attribute must be a text field for the sync to work.

If you need to create additional attributes in Hunter, visit the following page if you'd like to create a new Custom Attribute.

Once you’re done, you can click on Save settings. By completing these steps, you'll integrate Hunter with HubSpot, making lead management more efficient and effective.

To monitor the synchronization status of your leads, simply visit the Leads section and click on a lead. Look for the "Synchronization" status to determine if the lead has been successfully added to your CRM; it will display as "Saved" if it has.

Email addresses in Hunter are also not extracted from third-party databases; instead, they are publicly sourced from the web. This means Hunter works by scouring public web pages to find professional email addresses that are publicly available.

This provides several advantages, including full data transparency, compliance with CCPA and GDPR regulations, and the ability to update the identified emails regularly. You can find additional information on this on Our Data page.

Moreover, when exporting data, Hunter provides more than just email addresses; you get additional details for every email address when publicly available on the web, including:

  • First Name
  • Last Name
  • Department
  • Organization
  • Confidence score

  • Twitter handle

  • Phone Number

Hunter will also show you the source URLs where an email was discovered. This enriched data enables you to tailor your outreach efforts and improve your chances of success.

Verify a list of email addresses

If you already have a list of email addresses for your prospects but you’re not sure if they’re valid, you can use Hunter’s Bulk Email Verifier. It makes multiple checks to ensure the email addresses on your list are safe to contact. This also helps maintain a high-quality lead list and improves the effectiveness of your email outreach campaigns.

There’s also the individual Email Verifier tool, which you can use if you’re looking to verify a single email address.

Hunter's Bulk Email Verifier

Now, you might be wondering how to start the process of leveraging Hunter’s tools with your existing HubSpot contacts to find emails.

Here's a guide to get you started:

Step 1: Export your HubSpot contacts

First, export your HubSpot contacts as a CSV file, and ensure your CSV file includes the following information to get started, such as the First Name, Last Name, and Company Names or Domains.

Step 2: Upload the CSV file to

Step 4: Sync into HubSpot

Now that you have saved your enriched data into Hunter, it's time to sync them to HubSpot, allowing you to easily update your lead information with the new email addresses and other data you've acquired.

Another workaround for updating the existing records in HubSpot directly is that after finding some emails in Hunter, you can also import the records into HubSpot directly.

This will update the current contacts with new information when using the CSV option, as long as you are matching the new important with a Unique Identifier. For the Contact Records, the unique identifier is an Email Address by default.
