LastDatabase JIT verification performs supported verification and risk checks close to the time applicable records are prepared for delivery or export. This helps reduce the time between a verification event and customer delivery.
Learn how LastDatabase JIT verification works →How LastDatabase verifies supported contact data close to delivery or export.
Just-In-Time verification is a LastDatabase workflow for supported records that performs applicable verification and risk checks close to the time data is prepared for delivery or export. The purpose is to reduce the gap between an earlier data-quality check and the time a customer actually receives the record.
Contact data changes over time. Employees change jobs, domains change, mailboxes become inactive and phone information can be reassigned. JIT verification is designed to perform applicable checks closer to delivery rather than relying only on an earlier verification event.
For workflows where JIT is supported, verification is performed close to the applicable delivery, export or fulfillment event. The exact workflow can depend on the data type, product and delivery method.
Depending on the supported data type and workflow, JIT processing can include normalization, suppression checks, domain or MX checks, SMTP-related checks, classification and other applicable validation or risk signals. Not every check applies to every record or data type.
No. JIT availability and applicable checks depend on the product, record type and fulfillment workflow. A JIT statement for one supported workflow should not be interpreted as a claim that every record in every LastDatabase dataset receives identical checks.
No. Verification can reduce certain data-quality risks, but email delivery also depends on factors outside the database, including sender reputation, domain authentication, sending infrastructure, message content, recipient filtering and changes that occur after verification.
The action depends on the supported fulfillment workflow. A record may be classified, excluded, suppressed or handled through an applicable replacement process rather than being treated as a successfully verified record.
Database maintenance focuses on organizing, updating, normalizing and improving stored information over time. JIT adds applicable checks closer to a delivery or export event. The two processes address different points in the data lifecycle.
Read the How JIT Works documentation for more information about the supported workflow, checks and limitations.

Use the customer free-sample search to describe or search for the database you need. Available matching packages can then be presented for a sample request.
The sample system can support eligible database products available through the platform. Availability depends on the matching dataset and current sample rules.
A sample can help you inspect representative fields, formatting and the general structure of an eligible dataset before deciding whether it meets your requirements.
How customers can purchase or access supported records.
Pay Per Lead allows customers to purchase selected eligible records according to the pricing applicable to the data type or product rather than necessarily purchasing an entire database.
Yes. LastDatabase can provide monthly subscription access for supported account plans. Included record allowances, eligible data types and other conditions depend on the current subscription offering.
When the included allowance for an applicable subscription has been used, additional supported records can be subject to the applicable Pay Per Lead purchasing model.
Pricing can depend on data type, product, available records, purchasing model, quantity and other package-specific conditions. Review the applicable product or Pricing page for current information.
Working with LastDatabase data through supported CRM workflows.
Yes. LastDatabase provides supported CRM integration workflows that can allow authorized customers to work with selected data through compatible CRM systems.
LastDatabase documentation includes supported integration workflows for HubSpot, Zoho CRM and Salesforce. Available functionality can differ by integration.
Where supported by the applicable integration and account workflow, authorized customers can transfer selected eligible records using the available CRM integration functionality.
Supported integrations can provide field-mapping functionality so applicable LastDatabase fields can be associated with compatible CRM fields.
No. Access is governed by the authorization and permissions provided through the applicable integration. Customers should review the permissions requested by the specific CRM connection.
Use the LastDatabase documentation area for current setup instructions and supported CRM integration workflows.
Programmatic data access, matching and enrichment workflows.
Yes. LastDatabase provides API functionality for supported data and integration workflows. Features, limits and authorization depend on the applicable service or account.
Data enrichment uses submitted information to look for applicable matches and return available attributes from supported LastDatabase data where a suitable match can be identified.
No. Match availability depends on the submitted fields, available data, matching logic and the applicable dataset.
Customers should submit only information they are authorized to process and should not submit passwords, payment-card information, private cryptographic keys or unnecessary sensitive information.
JIT availability depends on the supported product and fulfillment workflow. API or integration access should not be assumed to apply identical JIT checks to every record unless the applicable workflow specifically supports them.
How to interpret verification, accuracy and changing contact information.
No. Contact and business information changes continuously. People change jobs, companies change domains, businesses relocate and contact information can become inactive or be reassigned.
LastDatabase uses applicable data-quality processes such as normalization, organization, deduplication, maintenance, classification and supported verification workflows. The exact process can differ by dataset.
Source and provenance can differ by dataset. Review the Data Sources documentation for information about source categories and related practices.
The Methodology page explains data-processing and quality concepts used across supported LastDatabase datasets and research.
Privacy rights, suppression and customer responsibilities.
Customers are responsible for evaluating their intended purpose and complying with laws, consent requirements and communications rules applicable to their activities and jurisdictions.
Use the LastDatabase Opt-Out & Data Removal process to submit an applicable request involving supported identifiers.
Suppression can retain a limited identifier or reference where appropriate to help prevent information that has been removed from being unintentionally reintroduced during later data processing.
