ReactIn is an intent-based marketing automation platform that connects dozens of data sources to trigger LinkedIn outreach at the right moment, with the right message.
Most LinkedIn automation tools work from static lists. You export a CSV, upload it, send the same sequence to everyone. ReactIn works differently. Instead of starting from a list, ReactIn starts from a signal. Someone engaged with your LinkedIn post. Someone filled your Tally form. Someone booked a call on Cal.com. Someone appeared in a Sales Navigator search. Someone connected with you on LinkedIn. Someone interacted with a competitor's content. ReactIn captures these signals, builds dynamic lead lists automatically, and triggers personalized outreach the moment a prospect shows intent.
Under the hood, ReactIn aggregates data from multiple providers: LinkedIn and Sales Navigator for professional targeting, Tally and Cal.com for inbound intent capture, Zapier and Make for no-code workflow automation, and a direct API for teams who want to build custom integrations. This means your outreach list is never static. It updates in real time as new signals come in, new forms get submitted, new connections arrive, new searches match your criteria.
From these dynamic lists, ReactIn runs multi-step LinkedIn campaigns: connection requests, message sequences, follow-ups, and lead magnet distribution. Campaigns are built on a visual workflow editor. Messages are personalized with dynamic variables tied to the prospect's context, company, role, or the specific signal that triggered the outreach.
ReactIn is used by B2B SaaS founders, GTM teams, sales managers, and lead generation agencies. The platform supports single accounts and multi-account setups, with an Agency plan designed for teams managing 10 or more LinkedIn profiles with white-labeling and permission controls.
Users consistently report reply rates between 27% and 57%, compared to the 5 to 8% industry average for cold LinkedIn outreach. The difference is not the volume. It is the timing. Reaching a prospect 10 minutes after they engaged with your content is not cold outreach. It is intent-based selling.
