How to verify your HubSpot contact list
Four steps. No OAuth. No plugins required.
Export contacts from HubSpot
In HubSpot, go to Contacts → All contacts → select your contacts or a list → Actions → Export. Download the CSV with email addresses.
Upload to StopBouncing
Create a free account and upload your exported CSV. StopBouncing detects the email column automatically and begins verification.
Download verified results
Once complete, download your results file. Every address is labelled Valid, Invalid, Unknown, or Disposable with a confidence score.
Update your HubSpot contacts
Filter for Invalid addresses, then use HubSpot's bulk update or import to unenrol them from active workflows and marketing emails.
Why HubSpot teams use StopBouncing
Protect your HubSpot email health score
HubSpot tracks bounce rates per connected domain. Sustained high bounces lower your health score and restrict your ability to send marketing emails.
Reduce inflated contact tier costs
HubSpot pricing is based on the number of marketing contacts. Invalid addresses that were never engaged count toward your billing — removing them lowers your tier.
Avoid marketing email suspensions
HubSpot can suspend outgoing email access for accounts with persistent deliverability issues. Clean lists before large sends to stay within safe bounce thresholds.
GDPR-safe contact handling
All data uploaded to StopBouncing is automatically deleted within 48 hours. No data is shared with third-party ad platforms or analytics providers.
Simple, pay-as-you-go pricing
No monthly subscription. No minimum spend. Pay only for what you verify.

Frequently asked questions
Does StopBouncing connect directly to HubSpot?
StopBouncing uses CSV export and import — the format HubSpot supports natively. Export your contacts from HubSpot, upload to StopBouncing, then use the results to update your HubSpot contact database. No native integration or OAuth connection is required.
How do I handle the Invalid addresses after verification?
In HubSpot, you can import a CSV of Invalid addresses and set a custom property (e.g. 'Email Status = Invalid') to segment them out of active workflows. Alternatively, use the bulk unenrol or opt-out feature to remove them from marketing email sends.
Should I verify my entire HubSpot database or just active lists?
Both are valuable. For immediate impact, verify the lists tied to your next campaign or automation. For a full database clean, export all contacts with a marketing email opt-in status and verify in one batch. For large databases, credits-based pricing means you only pay for what you verify.
What's the cost to verify a HubSpot contact database?
StopBouncing charges €0.0006 per email with no monthly fee and no minimum. 50,000 HubSpot contacts cost €30 to verify. 200,000 contacts cost €120. Credits never expire, so you can verify at your own pace.
Can StopBouncing verify emails via API before they enter HubSpot?
Yes. If you have forms powered by your own frontend or a custom integration, the StopBouncing API can validate email addresses at the point of submission — before they ever reach HubSpot. This prevents invalid contacts from entering your CRM in the first place.
