# Send

Send a message or a batch of messages.

Depending on the length of the body, one message might be split into multiple parts and charged accordingly.

Any groups targeted in a scheduled batch will be evaluated at the time of sending. If a group is deleted between batch creation and scheduled date, it will be considered empty.

Be sure to use the correct region in the server URL.
