Why should you validate your HubSpot email list?
Verifying your email list in HubSpot CRM is a necessary step for improving and maintaining email deliverability. Clearout's HubSpot email verification integration securely syncs data both ways, so you can strip out bad, disposable, and fake addresses before you ever hit send. With a clean list, more of your emails land in the inbox - not the spam folder - and your sender reputation stays protected.
How it works
How Clearout cleans your HubSpot lists
One secure connection handles the entire validation loop - no exports, no re-uploads, no manual cleanup.
Connect once, use anywhere
Link your HubSpot account securely in a couple of clicks - no CSV exports or manual uploads, and you can connect multiple accounts.
Deep, accurate checks
Every address is checked for syntax errors, disposable domains, role-based inboxes, spam traps, and invalid or risky mailboxes.
Pick your own scope
Validate your entire HubSpot account or just the specific lists and segments you choose - down to a single campaign list.
Results synced back automatically
Auto-unsubscribe invalid contacts or append Clearout's verification columns straight onto your existing HubSpot records.

- Works on native, embedded & landing page forms
Data Pulse
Watches for new contacts as they land in HubSpot - from imports, integrations, or manual entry - and validates them automatically.
- Checks contacts the moment they're created
- Keeps lists clean between manual clean-ups
Use cases
When teams verify their HubSpot CRM contacts
Most HubSpot databases do not go bad all at once. These are the moments when a verification run pays for itself.
Pre-campaign list hygiene
Verify a HubSpot list right before a big send, so bounces do not pile up mid-campaign and drag down your sender reputation.
Cleaning an inherited database
Taken over a HubSpot portal with years of accumulated contacts? Verify the whole database before you email any of it.
Post-import cleanup
Event lists, spreadsheet uploads, and third-party data arrive unverified. Check them once they land in your CRM.
Re-engaging dormant contacts
People change jobs and addresses go stale. Verify before a win-back campaign so you are not mailing mailboxes that no longer exist.
Cleaner handoffs to sales
Give reps contacts that are confirmed reachable, so prospecting time goes into conversations instead of undeliverable addresses.
Recovering from a bounce spike
After a bad send, verify the affected lists and unsubscribe the undeliverables to bring your bounce rate back under control.

Jeroen Riesewijk
Senior B2B Digital Marketeer at Novulo
Solid HubSpot integration that does what we need. Clearout is working properly and automatically helps us identify email addresses that no longer exist, so they can be removed from HubSpot. This saves us from having to manually clean outdated email addresses and helps keep the database in better shape. The overall experience has been good and the integration is working as expected.
