How to Integrate LastDatabase with HubSpot

Connect your LastDatabase account with HubSpot CRM and send eligible, verified business contacts directly to your HubSpot account.

The LastDatabase HubSpot integration helps customers move selected business contact data from LastDatabase into HubSpot without manually exporting and importing files.

What the integration does: LastDatabase checks selected email records against its suppression and email verification processes before eligible contacts are sent to HubSpot. Existing HubSpot contacts can be updated and new contacts can be created.

Before You Start

You need:

An active LastDatabase customer account.
Access to a HubSpot account where you can authorize applications.
Permission to access and manage HubSpot contacts.

1. Connect HubSpot to LastDatabase

Sign in to LastDatabase.
Open your LastDatabase customer account and go to the CRM Integrations section.
Select HubSpot.
Choose the HubSpot integration and click the option to connect your HubSpot account.
Authorize LastDatabase.
You will be redirected to HubSpot. Select the HubSpot account you want to connect and approve the requested contact permissions.
Return to LastDatabase.
After successful authorization, HubSpot redirects you securely back to LastDatabase. Your HubSpot connection will then appear as connected.

LastDatabase uses OAuth authorization. You do not provide your HubSpot password to LastDatabase.

2. Find Contacts in LastDatabase

Use the LastDatabase customer search tools to find the contacts you need. Available targeting can include criteria such as country, industry, job title, company and other available database fields.

Choose the records you want to work with and use the CRM export option for the selected records.

3. Verification Before CRM Delivery

Email records are not sent directly to HubSpot simply because they were selected.

Before delivery, LastDatabase applies its delivery eligibility process. This includes suppression screening and email verification.

For email delivery, only records meeting the required verification status are eligible to continue to the CRM export process. Records that do not meet the delivery requirements can be skipped.

This means the number of contacts successfully delivered to HubSpot can be lower than the number originally selected.

4. Send Contacts to HubSpot

After selecting eligible contacts, choose the HubSpot CRM export option.

LastDatabase processes CRM exports asynchronously. You can continue using your account while the export is processed.

For each eligible contact, LastDatabase:

Checks the contact's email address in HubSpot.
Looks for an existing HubSpot contact with that email.
Updates the existing contact when a match is found.
Creates a new HubSpot contact when no matching contact exists.

Email is used as the primary contact matching field for this workflow.

5. Contact Fields

Depending on the data available for a selected record and your configured field mapping, LastDatabase can send the following fields to HubSpot:

LastDatabase field	HubSpot contact property
Email	Email
First name	First name
Last name	Last name
Job title	Job title
Company name	Company
Company website	Website
City	City
State	State/Region
Postal code	Postal code
Country	Country

Email is required for the current email-contact integration. Other fields depend on whether that information is available in the selected LastDatabase record.

6. Check Export Status

LastDatabase records the processing status of CRM exports and their individual records.

Depending on processing results, records may appear as:

Successful — the eligible record was delivered to HubSpot.
Skipped — the record was not eligible for delivery.
Failed — the CRM delivery could not be completed.

An export containing both successful and skipped or failed records may show a completed-with-errors status.

7. Updating Existing HubSpot Contacts

LastDatabase searches HubSpot for an existing contact using the email address before creating a new contact.

When a matching contact exists, the integration updates that contact instead of intentionally creating another contact with the same email address.

8. Disconnect HubSpot

You can disconnect your HubSpot integration from the LastDatabase CRM Integrations area.

Disconnecting removes the active HubSpot authorization credentials stored by LastDatabase for that connection. It does not delete contacts that were previously delivered to your HubSpot account.

Troubleshooting

HubSpot does not connect

Confirm that you are signed in to the correct HubSpot account and that you have permission to authorize applications.

Some selected contacts were not sent

A selected email record may be skipped when it does not satisfy the LastDatabase suppression or verification requirements at delivery time.

A contact already exists in HubSpot

The integration searches by email before creating a contact. When a matching contact is found, LastDatabase can update the existing HubSpot contact.

The export is still processing

CRM exports are processed in the background. Check the CRM export status in your LastDatabase customer account.

Security and Access

The HubSpot integration uses OAuth authorization. LastDatabase stores the authorization credentials required to communicate with HubSpot for the connected customer account.

The integration is designed for contact operations required by the LastDatabase-to-HubSpot workflow. It does not provide a general two-way synchronization of all HubSpot CRM data.
