How to Connect HubSpot
No API keys. Just log in and authorize. The whole process takes under a minute.
Start the Connection
Go to Integrations in your ValidEmailChecker sidebar or click Connect Email Platformfrom the Bulk Upload page. Find HubSpot and click it. Enter an optional connection name — especially helpful if you manage multiple HubSpot portals (e.g., "Marketing HubSpot" or "Client ABC").
Authorize with HubSpot
Click Connect to HubSpotand you will be redirected to HubSpot's secure authorization page. If you have multiple HubSpot accounts, select the one you want to connect. Review the permissions ValidEmailChecker is requesting, then click Choose Account to authorize. You will be redirected back automatically.
What we access: We request read access to your contacts and lists so we can import them for verification. We never modify your HubSpot data unless you explicitly choose "Clean list automatically." We never send emails, access deals, or modify account settings.
Select a List and Configure
After authorizing, click Sync Now to see all your HubSpot contact lists with counts. Use the search box to find specific lists. Select the list you want to verify — All Contacts for your entire CRM, a static list for manually curated contacts, or an active list for dynamic segments. Choose Verify Only or Clean Automatically and configure your cleaning preferences.
Important: "All Contacts" can be very large. Consider verifying specific lists first if your CRM has hundreds of thousands of contacts. Start with "Verify Only" on your first run.
Track Results in Real Time
Click Import Listand you will be redirected to Uploads & Results. Progress updates automatically — no refreshing needed. When complete, you get a full breakdown: safe, invalid, risky, disposable, catch-all, and more. Download results in CSV, XLSX, JSON, or TXT. If you chose automatic cleaning, changes are already applied to your HubSpot contacts.

Managing Your HubSpot Connection
Connection Actions
Click the three-dot menu next to any connection on your Integrations page:
Sync Now
Refresh your contact lists from HubSpot immediately.
Rename
Change the connection display name.
Delete
Remove connection. Does not affect HubSpot.
When to Sync:
Multiple Portals
Running an agency? Connect as many HubSpot portals as you need.
Go to Bulk Upload → Connect Email Platform
Select HubSpot and see existing connections
Click "+ Add Another Account"
Complete OAuth and give it a unique name
Name each connection clearly: "Marketing Portal," "Client — ABC Corp," "Sales Team HubSpot."
Credits & Billing
1 Credit = 1 Email
Same rate as all other verification methods.
Unknown = Refunded
Credits returned instantly for unverifiable emails.
Duplicates = Free
Removed before charging — you only pay for unique emails.
Connecting = Free
Syncing your CRM never uses credits.
Credits Running Low?
If you do not have enough credits for your list size, you can purchase more credits instantly or set up auto-refill so you never run out during a critical verification.
Team Member Access
Team members can use connected HubSpot integrations and run verifications using the shared team credit balance. Only the account owner can add or remove connections.
Understanding HubSpot List Types
All Contacts
Your entire CRM database — every contact regardless of list membership, lifecycle stage, or source.
Best for:
Static Lists
Manually curated contact lists. Contacts are added or removed manually — they do not change automatically.
Best for:
Active Lists
Dynamic lists based on filters and criteria. Contacts enter and leave automatically as they match conditions.
Keep in mind:
HubSpot-Specific Tips
HubSpot stores more than just email addresses. Here is what you need to know about verification in a CRM context.
What Gets Checked
CRM Best Practices
For Agencies
Connect each client's HubSpot portal as a separate connection with a clear name. Run verifications independently per client. Use "Verify Only" first so you can share results with your client before making any changes to their CRM.
Troubleshooting
Cannot Connect to HubSpot
Make sure you have Admin or Super Admin permissions in HubSpot to authorize third-party apps. Try logging into HubSpot directly in a new tab first, then retry the connection. If pop-ups are blocked, allow them for ValidEmailChecker.
Authorization Failed
Log into HubSpot directly to confirm your account is in good standing, then try reconnecting. If you have multiple HubSpot accounts, ensure you selected the correct one during the authorization step.
Wrong Account Connected
Delete the existing connection from your Integrations page and reconnect. During the OAuth step, make sure to select the correct HubSpot account from the account picker if you have multiple portals.
Lists Not Showing
Click Sync Now to refresh your lists. Ensure your contacts have email addresses — contacts without emails will not appear. Only lists you have access to in HubSpot will be visible. Check that your HubSpot connection is still active.
"All Contacts" Is Too Large
Consider verifying specific static or active lists instead of your entire CRM. Create a targeted list in HubSpot for the contacts you want to verify, then select that list. This uses fewer credits and completes faster.
Connection Shows "Disconnected"
OAuth tokens can expire over time. Delete the existing connection and reconnect using the same OAuth process. Re-authorizing refreshes your access token. Your previous verification history remains in ValidEmailChecker.

Frequently Asked Questions
Only if you choose "Clean list automatically" and select Unsubscribe or Delete actions. With "Verify Only," your HubSpot data remains completely unchanged. We never modify contact properties, activity history, or deal data — only email subscription status if you explicitly choose auto-cleaning.
All HubSpot plans work — Free, Starter, Professional, and Enterprise. You just need Admin or Super Admin permissions to authorize third-party apps through OAuth. Once connected, any team member in ValidEmailChecker can use the integration.
Not directly through our integration. However, you can create a list of contacts that enter specific workflows, verify that list periodically, and use the results to update your workflow enrollment criteria. This gives you clean contacts entering every automation.
We recommend monthly verification for active marketing lists, quarterly for your entire CRM database, before every major campaign for critical sends, and immediately for newly imported contacts. Email data decays at roughly 2% per month, so regular verification prevents small problems from becoming big ones.
No. ValidEmailChecker verifies emails independently using our own infrastructure. We do not send any emails through HubSpot or count against your sending limits. Your HubSpot quotas are completely unaffected.
Yes. Team members in ValidEmailChecker can use connected integrations and run verifications using the shared team credit balance. However, only the account owner can add or remove HubSpot connections.
OAuth tokens can expire over time. If your connection shows as disconnected, simply delete it and reconnect using the same process. Re-authorizing refreshes your access token. Your previous verification history remains in ValidEmailChecker.
Absolutely — this is especially useful for agencies managing multiple client portals. Connect as many HubSpot accounts as you need. Give each a unique name like "Client — ABC Corp" or "Marketing Portal" so you can tell them apart.
Active lists in HubSpot are dynamic — contacts can enter or leave based on criteria. Verification results reflect the list at the moment of import. We recommend verifying active lists periodically or creating a static list snapshot for a point-in-time audit.
No. Connecting and syncing your account is completely free. You only use credits when you actually verify emails — 1 credit per email, same as every other verification method. Duplicates are removed before charging.
