Reply to conversation
Send a reply in a Conversations thread with Send Reply.
MCP tool postscript_write → reply_to_conversation
write Confirm
Sends one text message in the thread to the subscriber. It counts as usage, as a campaign would, and works for US and Canadian subscribers. It does not Resolve the thread or Opt Out the subscriber; both stay in the dashboard. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
|---|---|---|
| conversation_id string required | string | Thread from list_conversations. |
