Connect Hunter to your CRM, marketing tools, and sales workflows to speed up prospecting and verify contacts at scale.
What can you do with the Hunter connector?
Hunter is an email finder and verification platform used by sales and marketing teams to discover professional email addresses, verify deliverability, and build targeted prospect lists. Integrating Hunter with tray.ai lets you enrich leads automatically, trigger outreach sequences based on verified contact data, and keep your CRM clean without manual data entry. Whether you're scaling outbound sales or building automated lead generation pipelines, Hunter integrations cut out the friction between finding contacts and actually doing something with them.
Automate & integrate Hunter
Automating Hunter business processes or integrating Hunter data is made easy with Tray.ai.
Use case
Automated Lead Enrichment from Form Submissions
When a prospect fills out a form on your website or landing page, automatically pass their domain to Hunter to retrieve verified email addresses and company information. This enriched data gets pushed directly into your CRM, giving your sales team complete contact records without any manual research. The lag between a prospect expressing interest and your team having actionable contact information just disappears.
- Instantly enrich new leads with verified email addresses and company data
- Cut manual research time for SDRs and sales reps
- Improve lead-to-contact conversion rates with faster follow-up
Use case
CRM Contact Verification and Data Hygiene
Stale or invalid email addresses in your CRM hurt deliverability and waste your team's effort. Use Hunter's email verification API through tray.ai to periodically scan contacts in Salesforce, HubSpot, or Pipedrive and flag or remove invalid addresses. This automated hygiene workflow makes sure your outreach always targets deliverable addresses and keeps your sender reputation intact.
- Maintain high email deliverability by removing invalid addresses automatically
- Protect sender reputation and avoid spam traps
- Keep CRM data accurate without manual auditing cycles
Use case
Domain-Based Prospecting for Account-Based Marketing
For ABM campaigns, automatically feed a list of target company domains into Hunter to retrieve professional emails for decision-makers at those accounts. Combine this with enrichment from tools like Clearbit or LinkedIn to build detailed prospect profiles, then push them into your marketing automation or sales engagement platform. A domain list becomes a fully populated outbound campaign in minutes.
- Build targeted prospect lists from company domains at scale
- Feed verified contacts directly into ABM campaigns without manual exports
- Speed up account research and entry into outreach sequences
Use case
Outbound Sequence Enrollment Triggered by Lead Score
Connect Hunter with your lead scoring system so that when a contact hits a qualifying score in your marketing platform, their email gets verified via Hunter before they're enrolled in an outbound sequence. This prevents wasted sequence slots on undeliverable addresses and ensures your sales engagement platform only works with clean, verified contacts. Verification acts as a quality gate before any touchpoint fires.
- Prevent bounced emails from high-priority outreach sequences
- Automate the quality gate between lead scoring and sales engagement
- Increase email sequence ROI by only targeting deliverable addresses
Use case
Real-Time Slack Alerts for Verified High-Value Prospects
Build a workflow where Hunter verifies and enriches inbound leads in real time, and if the contact matches your ideal customer profile, a Slack notification goes immediately to the relevant sales rep. It's a hot-lead alerting system that means your team never misses a high-intent prospect because of slow manual processes. Reps can follow up within minutes of a verified lead entering your system.
- Alert sales reps instantly when verified high-value prospects come in
- Cut response time to high-intent leads dramatically
- Make sure the right rep gets the right lead based on territory or segment rules
Use case
Bulk Contact Discovery for Event or Conference Follow-Up
After a trade show or conference, your team has business cards and company names but often lacks full contact details. Use tray.ai to pass collected company domains in bulk through Hunter to retrieve verified emails for attendees or booth visitors. The enriched list syncs automatically to your CRM or email platform, so you can follow up while leads are still warm.
- Convert partial event contact data into complete, verified prospect records
- Automate post-event outreach prep to cut turnaround time
- Sync enriched event leads directly to CRM and email tools without exports

Challenges Tray.ai solves
Common obstacles when integrating Hunter — and how Tray.ai handles them.
Challenge
Managing Hunter API Rate Limits During Bulk Prospecting
Hunter's API enforces rate limits on requests, which becomes a real problem when processing large batches of domain searches or email verifications. Teams often hit throttling errors when trying to enrich thousands of leads at once, causing workflows to fail mid-execution and leaving data in inconsistent states.
How Tray.ai helps
tray.ai has built-in rate limiting controls, retry logic, and loop throttling so you can process large Hunter API batches without breaking your workflow. You can configure request pacing, automatically retry failed calls with exponential backoff, and split large jobs into manageable chunks — so bulk enrichment completes reliably without anyone babysitting it.
Challenge
Routing Low-Confidence or Unverified Email Results
Hunter returns confidence scores and verification statuses that vary — some emails are deliverable, others are risky or undeliverable. Without conditional logic in your workflow, low-quality results get pushed into your CRM or outreach tools right alongside clean data, polluting your pipeline and hurting deliverability.
How Tray.ai helps
tray.ai's conditional branching lets you build verification gates that route Hunter results based on confidence scores and verification status. Deliverable contacts move forward automatically, risky ones get flagged for human review in a Slack channel or task queue, and undeliverable results are cleanly rejected — all within the same workflow.
Challenge
Keeping Multiple Systems in Sync When Contact Data Changes
When Hunter verifies or enriches a contact, that data needs to show up consistently across your CRM, sales engagement platform, and marketing tools. Manually updating multiple systems after every verification run is error-prone and slow, and partial updates create data inconsistencies that affect campaign performance.
How Tray.ai helps
tray.ai acts as a central orchestration layer, writing Hunter enrichment results to all connected systems in a single workflow execution. A verified email update can simultaneously write to Salesforce, update an Outreach prospect, and tag a Mailchimp contact — every system reflects the same clean data without duplicated effort.
