Phone-only vs multichannel system
Phone alone burns lists fast. Phone connected to email, LinkedIn and signals creates more context.

Key terms
- ICP (ideal customer profile)
- The segment of companies and decision-makers most likely to buy, defined by industry, size, geography, language and signals. It is the filter that avoids blind volume.
- Buying signal
- An observable event, such as a funding round, a hire or a tool change, that shows an account is more likely to buy now.
- Multichannel outbound
- A coordinated sequence across email, LinkedIn and phone, aligned on the same target and message, instead of a single isolated channel.
- Qualified meeting
- A meeting with a decision-maker who fits the ICP and shows verified interest, not just a click or a polite reply.
