Hello,

I am trying to use the single send transactional send (POST request), but no matter what mail addreses I try I get this error when checking the send's status:

"sendResult":"INVALID_TO_ADDRESS"

Please advise

Hey @EStoller 👋. Great question. In my experience, this is typically a result of using a temporary or throw-away domain.

Are the addresses you are working with temporary-type domains?

Thanks! – Jaycee

Hi @Jaycee_Lewis,

Actually the problem was the other "to" fields - 'cc' and 'bcc', not the legitimate address in the "to" field. They were populated with an example array that didn't contain a proper email. Something like ["string"]. Removing those fields/populating them with proper emails solved the problem.

Big thanks to Tom from support that helped me with that one.
