A typical wiring for [send email batch](https://docs.rual.nl/block-types/lettermint/lettermintconnection_send_email_batch): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [open connection](https://docs.rual.nl/block-types/lettermint/lettermintconnection_open) feeds the `connection` pin; [with values](https://docs.rual.nl/block-types/array/array_of_values) feeds the `emails` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
