Multi-channel sequences

What it is

Single-channel outbound is leaving meetings on the table. LinkedIn-only campaigns top out around 8–14% reply rates because not everyone checks LinkedIn weekly. Email-only campaigns top out around 2–6% because cold email deliverability has cratered. Multi-channel sequences land in the 12–22% range.

The trick is coordination — sending the same message on three channels is spam. Different channels need different copy, and the sequence has to stop on a channel as soon as the prospect responds on any other.

Why multi-channel beats single-channel

Roughly 60% of B2B prospects don't check LinkedIn weekly. They check email daily.

Roughly 30% of B2B prospects (especially senior executives, international, and operations roles) prefer WhatsApp for short business asks.

Multi-channel reaches the prospect where they actually pay attention. The same prospect, reached on the right channel, replies. Reached on the wrong channel, they don't.

Channel order that works in 2026

Day 1: LinkedIn connection request (no note for warm prospects, short note for cold).

Day 4: Email follow-up if not yet accepted on LinkedIn.

Day 7: LinkedIn message if accepted; second email if not.

Day 10: WhatsApp message (only for prospects with verified phone numbers).

Day 14: Final email + LinkedIn follow-up, then auto-pause.

This is the default. Customizable per campaign or per prospect persona.

Channel-aware copy

Same idea, three voices. The LinkedIn message is short and curious (60-80 words). The email expands with detail and one CTA (180-220 words). The WhatsApp message is one sentence with the calendar link.

Infonet's AI generates each channel's variant from a single campaign brief — you don't write the same content three times.

Channel etiquette is enforced. WhatsApp can't carry a 200-word message; LinkedIn shouldn't carry a 30-word one without context. The AI respects the channel's norms.

Stop-on-reply across channels

The moment a prospect replies on any channel, the entire sequence stops on every other channel. No more emails after they replied on LinkedIn. No more WhatsApps after they emailed back.

This is the most-requested feature among teams migrating from less-coordinated tools — and it's the difference between feeling thoughtful versus feeling spammed.

Stop-on-reply also respects sentiment. A 'not interested' reply moves the prospect to a 'no' status; a question reply moves them to 'engaged' for human follow-up.

Email deliverability

The cold-email channel is hard in 2026. Apple Mail Privacy has broken open-tracking; Google's filters are aggressive; reply-to addresses get burned weekly.

Infonet's email channel uses warmed-up custom domains, SPF/DKIM/DMARC properly configured per profile, and pacing under typical spam thresholds.

Email deliverability is monitored per-profile. Profiles whose deliverability degrades get auto-paused on email and continue on LinkedIn + WhatsApp until they recover.
