The caller is responsible for specifying if the message contains Unicode characters.

Boolean

Sender

We recommend you to specify this value only when you are confident about the delivery result (e.g. you've already tested it using the MailUp web platform), otherwise it is better to not specify this parameter in the request.

In addition, in some countries the sender may be subject to local restrictions and it may be overwritten by the carriers before being delivered. You can contact us if you need support for some specific nations.
