Email alone is ignorable. LinkedIn alone is noise. Ads alone are wallpaper. But when someone sees your name three ways in one week and every touchpoint feels made for them, that is when the meeting gets booked.
The problem is that most teams run multichannel like it is three separate campaigns happening to share a calendar. The email team sends emails. The social team posts on LinkedIn. The ads team runs retargeting. Nobody talks to each other.
Real multichannel means each channel knows what the others are doing. If someone opened your email but did not reply, LinkedIn should pick up the thread. If they clicked an ad, the follow-up email should reference what they saw.
This requires an orchestration layer. Something that sits above all the channels and decides what happens next based on what just happened. It is not about more touches. It is about smarter touches.
I built this with Make.com sitting on top of HubSpot, LinkedIn, and a custom ad audience sync. When a contact takes an action in one channel, it triggers the right response in the next channel.
The result was not more outreach. It was less outreach that worked better.
The details matter. The system matters. But the thinking behind it matters more.
