400 - Invalid Email
Tip
The invalid_email error code is provided if you provide an invalid format of email address
When creating shipments, a contact is required for each address. For each contact, a valid email address is required.
For the purposes of validating email addresses, Sorted will simply ensure that the value provided matches the minimum requirements for an email address, not that the email address exists or is the correct email address for the contact it is listed against.
