What is Multichannel sequence?
One sequence mixing email steps with LinkedIn actions (visits, connection requests, messages) and calls, so a prospect meets you on more than one channel.
A multichannel sequence might go: email, wait 2 days, LinkedIn profile visit, wait 1 day, connection request with a note, wait until accepted, LinkedIn message, final email. Each channel has its own limits — LinkedIn's daily connection caps are far lower than email's — and a reply on any channel must stop the sequence on all of them. The alternative pattern is a LinkedIn campaign fed by an email campaign: only people who opened, clicked or replied move to LinkedIn.
