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.
HubSpot + Hunter integration
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.
When sales reps manually copy emails from Hunter into HubSpot, errors pile up, duplicates multiply, and hours of selling time disappear. By connecting Hunter with HubSpot through tray.ai, your team can automatically enrich new HubSpot contacts with verified email addresses, validate existing records in bulk, and trigger outreach sequences the moment a high-confidence email match is found. The result is a cleaner CRM, a faster top-of-funnel, and a sales team spending its time on actual conversations instead of spreadsheets.
Automate & integrate HubSpot + Hunter
Automating HubSpot and Hunter business processes or integrating data is made easy with Tray.ai.
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.
- Eliminate incomplete HubSpot contact records caused by missing email fields
- Cut manual research time for SDRs and BDRs by automating email discovery
- Improve email deliverability by running Hunter's verification before any outreach
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Over time, HubSpot databases fill up with bounced, outdated, and unverifiable email addresses that hurt sender reputation and campaign performance.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.
- Protect sender reputation by proactively identifying invalid or risky emails
- Cut HubSpot marketing email bounce rates with regular verification passes
- Automatically tag or suppress unverifiable contacts before campaign sends
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.
- Instantly populate HubSpot with multiple contacts from a target account domain
- Automatically assign lifecycle stage and contact owner based on enrichment rules
- Speed up ABM campaigns by removing the manual prospecting step entirely
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.
- Pull email confidence data directly into HubSpot lead scoring logic
- Get your highest-priority leads in front of sales reps faster
- Stop wasting outreach effort on low-confidence or unverifiable contacts
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.
- Verify form-submitted emails in real time before they enter HubSpot workflows
- Block disposable or role-based email addresses from entering your CRM
- Improve the quality and accuracy of inbound lead data at the source
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.
- Maintain a continuously refreshed pipeline of prospects at named target accounts
- Automatically associate Hunter-discovered contacts with existing HubSpot company records
- Give sales reps a steady stream of net-new contacts without additional research burden
Challenges Tray.ai solves
Common obstacles when integrating HubSpot and Hunter — and how Tray.ai handles them.
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 helps
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 helps
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 helps
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.
Templates
Pre-built workflows for HubSpot and Hunter you can deploy in minutes.
Enrich New HubSpot Contacts with Hunter Email Lookup
HubSpot 
Hunter This template monitors HubSpot for newly created contacts missing email addresses. It extracts the contact's first name, last name, and company domain, submits a lookup request to Hunter's Email Finder API, and writes the discovered email and confidence score back to the HubSpot contact record as custom properties.
Verify Existing HubSpot Contacts' Emails with Hunter
HubSpot Hunter This template runs on a schedule to pull HubSpot contacts that haven't been verified, sends each email to Hunter's Email Verifier API, and updates the contact record with a verification result. Contacts flagged as invalid are automatically tagged for suppression or routed to a data cleanup list.
HubSpot Domain Search Prospect Import from Hunter
HubSpot Hunter This template accepts a company domain as an input, triggers a Hunter Domain Search, retrieves all publicly associated professional emails, and creates or updates HubSpot contacts for each discovered email under the relevant company record with the appropriate lifecycle stage and owner assignments.
Real-Time Form Submission Email Verification Gate
HubSpot Hunter This template intercepts HubSpot form submissions via webhook, immediately verifies the submitted email through Hunter's Verify API, and routes the contact to either a standard nurture workflow for valid emails or a review queue for invalid or disposable addresses.
Deal Stage Contact Enrichment Check
HubSpot Hunter This template fires when a HubSpot deal moves to a specified pipeline stage, reviews all associated contacts for missing or unverified emails, submits any gaps to Hunter for enrichment, and updates contact records before any deal-stage automation or email sequences run.
Scheduled HubSpot List Prospecting via Hunter Domain Search
HubSpot Hunter This template runs on a defined schedule against a HubSpot company list, performs a Hunter Domain Search for each company, and imports net-new contacts into HubSpot as prospects — a continuous, automated account-based prospecting motion that runs without manual SDR effort.
