Send preview
Text a preview of a campaign message to one phone number.
MCP tool postscript_write → send_preview
write Confirm
Uses Send Preview next to the message in Flow Builder and the phone number you give. It reaches a real phone and counts as usage, so use your own number. Returns sent once Postscript accepts it. By default you confirm each call; you can switch that off for this tool.
