What is Cold outreach?
Contacting prospects who don't know you, across one or more channels — email, LinkedIn, phone — to start a sales conversation.
Cold outreach is the broader term for cold email plus the other channels used alongside it: LinkedIn connection requests and messages, phone calls, occasionally SMS. A multichannel sequence combines them — an email, then a LinkedIn profile visit, then a connection request, then a call — so the prospect meets you in more than one place.
The operational challenge is coordination: each channel has its own limits (daily sends, LinkedIn's connection caps), and a reply on one channel should stop the sequence on all of them.
