What should I use to validate emails before importing into HubSpot?

Use an email validation tool that checks deliverability, not just format. Before importing into HubSpot, the best options are typically:

• ZeroBounce
• NeverBounce
• BriteVerify
• Kickbox
• Xverify (more enterprise-focused)

These tools can help identify:

• invalid or misspelled emails
• disposable/temporary addresses
• catch-all domains
• role-based addresses like info@ or sales@
• risky or low-quality contacts

Best practice for HubSpot imports

1. Validate the list first with one of the tools above.
2. Remove hard bounces / invalids / disposable emails.
3. Optionally segment risky contacts instead of deleting them outright.
4. Import only cleaned contacts into HubSpot.

If you want the simplest recommendation

• NeverBounce or ZeroBounce are common choices for marketing lists.
• BriteVerify is often used for quick verification before import.
• Kickbox is solid if you want a balance of accuracy and ease of use.

Important note

Even validated emails can still bounce later, so also:

• confirm consent/compliance
• avoid importing old or purchased lists
• watch HubSpot bounce metrics after import

If you want, I can also recommend the best tool based on your list size, budget, or whether you need a HubSpot integration.
