HubSpot error: INVALID_EMAIL address format"

TL;DR

HubSpot rejects the contact because the email is malformed. Validate email format before import and quarantine the bad rows instead of failing the batch.

Error

HubSpot error: INVALID_EMAIL

Steps

1. Find the malformed addresses in your import Expected: you see the bad rows.
2. Fix or remove them Expected: the data is clean.
3. Validate email format before sending Expected: bad rows never reach the API.
4. Re-run the import Expected: it succeeds.

When to use

• HubSpot INVALID_EMAIL
• Addresses are malformed

When not to use

• The addresses look fine (then check for hidden characters)
• You need the contacts anyway (then fix the data, not the API)

Tool compatibility

• Email validation
• HubSpot imports

Variant phrasings

hubspot invalid_email

Validate the address format before import.

INVALID_EMAIL hubspot

Same: the address is malformed.

Why it happens

Source data has typos and placeholders like 'none'. HubSpot validates strictly.

Edge cases

• International domains need proper encoding
• Plus-addressing is valid; do not strip it
