A new prospect engages with a monitored post, but the useful moment can pass before anyone follows up. Letterdrop helps social-selling teams spot activity through New Lead Generated, New Scraped Lead and monitored-post triggers. Through Zapier, Mobile Message can turn that signal into a timely SMS.

A lead that meets your Letterdrop filters can receive a personal text, be created as a Mobile Message contact, or be added to a list for a planned campaign. This gives sales operators another practical way to respond while the prospect's interest is current. New Post From Account Monitoring and New Post From Keyword Monitoring can also start SMS alerts for a team member, provided the Zap contains the relevant contact details. Letterdrop's Add Transcript action is not a customer-facing outcome on its own, so the strongest use here is sending or organising SMS outreach from Letterdrop events. The connection runs through Zapier rather than being a native two-way integration.
