# Message sent

> Origami POSTs this event to your configured URL when a sequencer
email or LinkedIn DM finishes sending.

Branch on `data.channel` (`"email"` or `"linkedin"`) to handle
the two channels. `data.message.provider_id` is the
provider-side identifier (Gmail `msgId`, LinkedIn chat message
id), useful for correlating with the user's own inbox.

**Default in the picker:** off.
