ZeroBounce + HubSpot
Keep Your HubSpot CRM Clean with ZeroBounce Email Validation
Automatically validate, score, and enrich every email address in HubSpot to protect deliverability and improve marketing ROI.
Why integrate ZeroBounce and HubSpot?
ZeroBounce and HubSpot are a natural pairing for any revenue team that runs on email. HubSpot houses your contacts, deals, and marketing campaigns, while ZeroBounce makes sure the email addresses behind those campaigns are valid, safe, and deliverable. Together, they cut the risk of bounces, spam traps, and toxic contacts that quietly erode sender reputation and mess with your CRM data.
Automate & integrate ZeroBounce & HubSpot
Use case
Real-Time Contact Validation on Form Submission
When a new contact enters HubSpot via a landing page, ad form, or manual entry, tray.ai immediately sends that contact's email to ZeroBounce for validation. The result and status code are written back to the HubSpot contact record within seconds. Sales reps and marketing automation workflows act on verified data from the very first touch.
Use case
Bulk List Validation Before Campaign Launch
Before sending a major email campaign or enrolling contacts into a HubSpot workflow, trigger a bulk ZeroBounce validation job against the target segment. tray.ai pulls the contact list, batches the records, submits them to ZeroBounce, and updates each HubSpot contact with a validation score and deliverability status. Only clean contacts get enrolled.
Use case
Automated Contact Tagging and Segmentation by Email Quality
ZeroBounce returns granular status codes — valid, invalid, catch-all, abuse, do-not-mail, and more. tray.ai maps these statuses to custom HubSpot contact properties and list memberships, so your team can segment, suppress, or prioritize contacts based on email quality without manual sorting. Marketing can build smart lists directly around these quality tiers.
Use case
Continuous Database Health Monitoring and Re-Validation
Email addresses decay at roughly 22% per year, so contacts that were valid six months ago may bounce today. A scheduled tray.ai workflow periodically re-validates HubSpot contacts that haven't been checked recently, updates their ZeroBounce status, and flags newly invalid records. Your CRM stays clean without anyone touching it manually.
Use case
Lead Scoring Enrichment with ZeroBounce Activity Data
ZeroBounce's Activity API returns data on how recently and frequently an email address has been active online. tray.ai pushes this activity score into HubSpot as a custom property, which feeds directly into HubSpot's lead scoring model. Leads with highly active email addresses get scored higher automatically, so sales teams know who to call first.
Use case
Suppression List Synchronization for Compliance and Deliverability
ZeroBounce identifies abuse and spam-complaint addresses that should never receive marketing email. tray.ai syncs these suppression records into HubSpot as opted-out or unsubscribed contacts, keeping them out of all future sends. This protects your brand from spam complaints and helps maintain compliance with CAN-SPAM and GDPR.
Use case
Invalid Contact Quarantine and Deal Hygiene Workflow
When ZeroBounce flags a contact's email as invalid, tray.ai can automatically move that contact to a quarantine list in HubSpot, pause any active sequences they're enrolled in, and notify the deal owner via a HubSpot task or Slack message. Sales reps stop working deals based on contact data that's going nowhere.

ZeroBounce & HubSpot Challenges
What challenges are there when working with ZeroBounce & HubSpot and how will using Tray.ai help?
Challenge
Managing Custom ZeroBounce Properties Inside HubSpot
HubSpot doesn't natively understand ZeroBounce status codes, sub-statuses, or activity scores. Without an integration layer, teams have to manually create custom properties and map ZeroBounce data fields to them — error-prone work that tends to produce inconsistent results across teams.
How Tray.ai Can Help:
tray.ai handles all of that mapping automatically. Every ZeroBounce API response field — status, sub-status, free email flag, activity score, and more — gets written to the right HubSpot custom contact property without any per-workflow field mapping on your end.
Challenge
Handling Large Contact Lists Without Hitting API Rate Limits
Bulk validating tens of thousands of HubSpot contacts against the ZeroBounce API requires careful batching, retry logic, and result polling. Exceed rate limits or mishandle asynchronous batch results, and you end up with incomplete validation runs and dirty data still sitting in the CRM.
How Tray.ai Can Help:
tray.ai's workflow engine handles batching, pagination, and asynchronous polling natively. It automatically chunks large HubSpot contact exports into ZeroBounce-acceptable batch sizes, polls for job completion, and resumes gracefully after any transient API error — giving you full coverage even on very large databases.
Challenge
Keeping Validation Status Fresh as New Contacts Continuously Flow In
HubSpot receives new contacts from dozens of sources simultaneously — forms, ads, imports, integrations, and manual entry. Making sure every new contact gets validated in near real time, without creating duplicate validation requests or race conditions, requires careful event-driven architecture.
How Tray.ai Can Help:
tray.ai listens for HubSpot contact creation events via webhook and deduplicates triggers before dispatching validation requests to ZeroBounce. Built-in idempotency controls prevent the same contact from being submitted multiple times, and the platform scales horizontally to handle high-volume contact creation spikes.
Challenge
Preventing Invalid Contacts from Entering Active HubSpot Sequences Mid-Enrollment
Contacts can be enrolled in HubSpot sequences before a validation result comes back, especially during high-volume periods. Without a hold-and-validate pattern, invalid emails may receive campaign messages, generating bounces and damaging sender reputation before the bad address is ever caught.
How Tray.ai Can Help:
tray.ai supports conditional branching and delay logic that holds a contact's enrollment in a HubSpot workflow until ZeroBounce confirms a result. Valid contacts proceed automatically. Invalid ones get routed to a suppression path instead, with no risk of a premature send.
Challenge
Maintaining Audit Trails for Compliance and Deliverability Reporting
Marketing and ops teams often need to explain why a specific contact was suppressed or why a campaign excluded certain addresses — for internal audits, GDPR data subject requests, or deliverability troubleshooting. HubSpot alone doesn't log ZeroBounce validation decisions.
How Tray.ai Can Help:
tray.ai logs every ZeroBounce validation call and result as part of its workflow execution history and can simultaneously write a timestamped note to the HubSpot contact record detailing the validation outcome, the date it was checked, and the specific status code returned — a full, searchable audit trail directly inside HubSpot.
