Send LinkedIn InMail
Send an InMail to someone outside your immediate network, reaching prospects you are not yet connected to. Requires a Sales Navigator subscription, consumes InMail credits, and accepts the recipient as a provider_id, profile slug, or full LinkedIn URL. The body is capped at 1900 characters and the optional subject at 200, and you can attribute the send to a campaign. Fails if the recipient has opted out of InMail or you have no credits remaining.
Example prompt: Send an InMail to ACoAABGDkeIB introducing our onboarding service with the subject Quick question about your hiring plans
