Hi, guys. I was trying to create a new object by [https://api.hubapi.com/crm/v3/objects/contacts](https://api.hubapi.com/crm/v3/objects/contacts) using an invalid email, and the error message returned was:

message: ‘Property values were not valid: [{“isValid”:false,“message”:“Endereço de e-mail tb.tb@yahoo.comtttt inválido”,“error”:“INVALID\_EMAIL”,“name”:“email”}]’

I know that this domains has a problem, but will this also happen with other valid domains such as @test.design, @test.vegas and others that don’t end with two or three digits??

When I apply a regex on these domains, including the invalid email in the message above, I always get a positive response, so I don’t know what the evaluation criteria is implemented by hubspot.

Hi @GdaSilvaCarlo,

HubSpot validates email addresses used for any process that would create or update a contact record. This includes using the [contacts endpoints](https://developers.hubspot.com/docs-beta/crm/contacts) to create or update a contact as well as [form submissions](https://developers.hubspot.com/docs/methods/forms/submit_form) or [events](https://developers.hubspot.com/docs/api/analytics/events).

These processes don’t check the email address itself for validity (like an [embedded form would](https://knowledge.hubspot.com/articles/kcs_article/forms/why-is-my-form-telling-me-to-enter-a-valid-email-address)), but rather its format. In addition to being valid according to [RFC 2822](https://tools.ietf.org/html/rfc2822), HubSpot places the following restrictions on email addresses:

- Local parts of the address cannot include quotation marks. (e.g. "Test [Email"@hubspot.com](mailto:Email%22@hubspot.com) isn’t valid)
- The domain part must end in a valid TLD, as listed at [https://data.iana.org/TLD/tlds-alpha-by-domain.txt](https://data.iana.org/TLD/tlds-alpha-by-domain.txt) (note that this is after handling unicode TLDs, so “user@email.삼성” is a valid email address).

Hopefully this helps in some way. For what it’s worth I was able to successfully create a contact using “POST /crm/v3/objects/contact” with email “xyz@test.design” and “abc.test.vegas”. Request information below:
