HubSpot + Hunter
Connect HubSpot and Hunter to Build Smarter Prospecting Pipelines
Automatically enrich, verify, and sync contact data between Hunter and HubSpot so your sales team can focus on closing deals.
Why integrate HubSpot and Hunter?
HubSpot and Hunter are a natural pairing for sales and marketing teams that run on accurate contact data. Hunter finds and verifies professional email addresses; HubSpot manages the relationships, sequences, and deal stages. Together, they cut out the manual work of researching prospects and make sure every contact entering your CRM is verified and ready to reach.

Use case
Automatic Contact Email Enrichment
When a new contact lands in HubSpot without an email address — from a form submission, LinkedIn import, or manual entry — tray.ai queries Hunter using the contact's name and company domain to find and verify a professional email. The enriched address is written back to the HubSpot contact record instantly, keeping your database complete and sales-ready.
Use case
Bulk CRM Email Verification and Data Hygiene
Over time, HubSpot databases fill up with bounced, outdated, and unverifiable email addresses that hurt sender reputation and campaign performance. With tray.ai, you can schedule recurring workflows that pull HubSpot contacts, run each email through Hunter's Verify API, and update the contact record with a verification status tag. Contacts flagged as invalid get automatically suppressed or routed to a data cleanup workflow.
Use case
Domain-Based Prospecting Into HubSpot
When your team targets a specific company or account, tray.ai triggers a Hunter Domain Search to pull all publicly available professional emails for that domain, then creates or updates corresponding contacts in HubSpot with the right company association, lifecycle stage, and owner assignment. No manual lookups, no data entry.
Use case
Lead Scoring Enrichment Based on Email Confidence
Hunter returns a confidence score with every discovered email address, reflecting how likely it is to be valid and active. tray.ai maps that score to HubSpot contact properties and folds it into your lead scoring models. Contacts with high-confidence emails get prioritized for immediate outreach; lower-confidence records go into a validation queue.
Use case
Inbound Form Submission Email Verification
When a prospect fills out a HubSpot form, tray.ai passes their submitted email to Hunter for real-time verification before the contact enters any nurture or sales sequence. If the email comes back as disposable, invalid, or low-confidence, the workflow routes the contact to a review queue or requests a corrected email — stopping bad data before it ever touches your CRM.
Use case
Competitor Account Prospecting Workflow
Sales teams tracking competitor accounts can use tray.ai to monitor a curated list of target company domains, trigger Hunter searches on a schedule, and push newly discovered contacts into HubSpot as prospects under the correct company record. It's a continuous, automated prospecting motion for named accounts — no manual SDR searches required.
Use case
Deal Stage Contact Enrichment Trigger
When a HubSpot deal advances to a stage like Proposal Sent or Contract Review, tray.ai checks whether all associated contacts have verified email addresses. Any contacts missing a verified email get sent to Hunter for enrichment, so deal-critical communications don't fail because of missing or outdated contact information.

HubSpot & Hunter Challenges
What challenges are there when working with HubSpot & Hunter and how will using Tray.ai help?
Challenge
Handling Hunter API Rate Limits During Bulk Enrichment
Hunter enforces monthly request limits and per-minute rate limits on its Email Finder and Verifier APIs. When you're enriching thousands of HubSpot contacts in bulk, workflows that don't account for this can burn through API quotas fast, triggering errors that leave large batches of contacts unenriched and pipelines broken.
How Tray.ai Can Help:
tray.ai's workflow engine has built-in rate limiting controls, retry logic, and loop throttling so you can pace Hunter API calls within safe thresholds. You can configure delay intervals between calls, set up exponential backoff on rate-limit errors, and spread bulk enrichment jobs across scheduled windows — full coverage without ever blowing your quota.
Challenge
Preventing Duplicate Contacts When Importing from Hunter
When Hunter returns multiple email matches for a domain search and those contacts get pushed to HubSpot in bulk, duplicate records can pile up fast — especially if the same email appears in multiple Hunter results or already exists in HubSpot under a slightly different format.
How Tray.ai Can Help:
tray.ai uses conditional branching and data lookup steps to check for existing HubSpot contacts by email or name before creating new records. If a match is found, the workflow updates the existing record instead of creating a duplicate, keeping your HubSpot database clean and your sales team working from a single source of truth.
Challenge
Mapping Hunter Confidence Scores to HubSpot Custom Properties
Hunter returns structured metadata — confidence scores, email sources, and verification statuses — that don't map directly to standard HubSpot contact properties. Without careful field mapping, this data gets discarded or stored inconsistently, which defeats the point of running the enrichment at all.
How Tray.ai Can Help:
tray.ai's data mapping and transformation tools let you define exactly how Hunter response fields translate to HubSpot contact properties. You can normalize confidence scores into labeled tiers, convert Hunter verification statuses into HubSpot custom properties, and build conditional logic that applies different property values based on score ranges — so every enrichment result is stored in a consistent, queryable format.
Challenge
Managing Enrichment for Contacts with Insufficient Domain Data
Hunter's Email Finder needs both a contact name and a company domain to return results. HubSpot contacts imported from LinkedIn, trade shows, or manual entry often lack a company domain, so Hunter lookups fail silently and leave enrichment gaps with no visibility into what went wrong.
How Tray.ai Can Help:
tray.ai lets you build pre-enrichment validation steps that check whether required fields like company domain are present before calling Hunter. If a domain's missing, the workflow can try to derive it from a HubSpot company association, trigger a fallback alert to the contact owner, or queue the record in a HubSpot list for manual review — turning silent failures into actionable tasks.
Challenge
Keeping Enrichment Data Fresh as Contact Information Changes
Email addresses verified or discovered today can go stale within months as professionals change jobs, companies rebrand, or domains expire. A one-time enrichment run leaves HubSpot contacts that gradually drift toward inaccuracy, hurting sender reputation and campaign performance along the way.
How Tray.ai Can Help:
tray.ai makes it straightforward to build scheduled re-enrichment workflows that periodically re-verify HubSpot contacts against Hunter, particularly those whose last verification date exceeds a configurable threshold. Contacts that fail re-verification get automatically flagged, suppressed from active campaigns, and routed to a data review queue — so CRM accuracy stays an ongoing process, not a one-time project.
