The second channel reaches the people the first one missed
An unanswered email rarely means no. It usually means unread. People live in different inboxes: one never opens recruiter email and answers a LinkedIn message the same day, another has not logged in to LinkedIn since spring and picks up the phone on the second ring. A single-channel sequence keeps knocking on the same door. A mixed cadence tries the next one.
The catch is the data. A cadence drawn on a whiteboard assumes everyone has an email, a profile and a number. A real list does not. Put forty people with no LinkedIn URL into a cadence that opens with a profile visit, and what happens next depends on the tool: some skip the step, some stall. Either way the cadence you designed is not the one those people get.
So this play takes the channel from the row. It counts what each person can be reached on, builds the cadence you chose, and gives each person the version of it that their data can carry.
What you get back
A count of the list by track: all three channels, no LinkedIn, no email, LinkedIn only. The messages for every step, with talking points for each call. The cadence built in your sequencer and paused, one track per campaign, people loaded. And a plain description of day one: what goes out on each channel, and how many call tasks a day will land on your desk once it runs.
Variations worth knowing
LinkedIn-led for candidates. Visit, connection request, a message once they accept, then a personal email, then a call. LinkedIn is usually already on the row, and it is where a candidate expects the approach.
Email-led for client contacts. Work email first, a LinkedIn touch between the emails, and the call after they have seen your name twice.
Missing numbers. Find mobile numbers for a shortlist fills them before the build, so more people qualify for the call step.
Email or LinkedIn only. Build an outreach sequence covers the single-channel shapes and any other sequencer.
Where this goes wrong
More call tasks than you can make. Two hundred people reaching the call step in one week is two hundred tasks. Load in batches sized to the calls you will really make.
A work email on a candidate row. It is the wrong channel for someone you are asking to leave that employer. Those rows go to the LinkedIn track.
One message pasted into three channels. The email, the LinkedIn message and the call should each move the conversation on, not repeat it.
Stop on reply. Check in your sequencer that an answer on any channel stops the rest. The play does not change campaign settings.
LinkedIn limits. Daily limits on the connected LinkedIn account are set in the sequencer, not by this play.
