Validate emails in HubSpot import CSVs

Email syntax issues are one of the most common import blockers. TidyImports flags invalid values and keeps issue triage fast.

What counts as an invalid email

• Missing @ symbol
• No domain or invalid domain (e.g. user@)
• Spaces inside the email address
• Blank email field on a contacts row (required field)
• Extra characters or formatting artifacts

How TidyImports validates emails

TidyImports runs format validation on every email cell and returns row-level feedback — so you know exactly which rows need fixing before export.
