Why multi-channel outperforms single-channel
A LinkedIn-only campaign tops out around 8–12% reply rates because half your prospects don't check LinkedIn weekly. Adding email picks up the lurkers; adding phone picks up the senior buyers; adding WhatsApp picks up the international segment.
Sequencing matters
LinkedIn first (low-friction connection), email second (more detail), phone third (high-intent only). Reverse the order and you'll get blocked.
Channel-aware messaging
The LinkedIn message is short and curious. The email expands with detail and CTA. The phone call confirms an already-warm conversation. Don't paste the email into LinkedIn.
How Infonet runs multi-channel
One sequence builder. LinkedIn invite, then email after 3 days, then WhatsApp after 5, then a phone task on day 9. Each step uses channel-appropriate copy.
