Multichannel outreach

What is multichannel outreach?

Multichannel outreach is the sales prospecting approach that coordinates contact across multiple communication channels — typically email, phone, and LinkedIn, with optional additions of video messages, direct mail, and SMS — in a structured sequence rather than relying on a single channel. Each channel reaches the prospect in a different context and at a different moment, increasing the cumulative probability of a connection.

The channel expansion from email-only to multi-channel became the standard approach in B2B sales from 2018 onward as inbox volume grew and email deliverability became harder to maintain at scale. A prospect receiving 50+ cold emails per day in their inbox has a much higher signal-to-noise ratio for a phone call or a specific LinkedIn message than for email number 51.

For SDRs running outbound, the math on multichannel is straightforward: each additional channel is an additional probability event. A prospect who doesn't open email may answer their phone. A prospect who doesn't answer the phone may reply to a LinkedIn DM. A prospect who ignores all three in week 1 may respond to a video message in week 2. Stacking channels stacks the probability of a connection.

The core channels and when to use each

Four channels make up the standard multichannel outreach stack. Each has different engagement dynamics.

• Email — asynchronous, scalable, leaves a paper trail. The backbone of most outbound sequences. Best for: initial outreach, follow-ups, sharing assets (case studies, ROI data). Limitations: high volume (prospects receive dozens daily), open rates affected by MPP, requires strong deliverability.
• Phone — synchronous, highest conversion per touch, requires the most effort and tolerance for rejection. Best for: breaking through to prospects who don't engage on email, re-engaging warm leads, time-sensitive signals. Limitations: difficult to scale without a dialer, low connect rates (3–15% depending on list quality), requires confidence and script preparation.
• LinkedIn — professional context, profile visibility, connection-based trust. Best for: warm outreach with shared connections, content engagement signals (prospect liked or commented on relevant content), sending after email opens without reply. Limitations: message request limits for non-connected profiles (InMail credits), generally lower reply rate than email or phone per contact.
• Video messages (Loom, Vidyard) — high differentiation, low volume. Best for: high-ACV accounts where standing out justifies the production time, re-engagement of warm prospects who have gone quiet. Limitations: time-intensive to produce at scale, diminishing returns if used too broadly.

How to sequence channels effectively

Channel sequencing matters as much as channel selection. The pattern that consistently performs well:

Day 1: Signal-triggered email. Day 3: Follow-up email (different angle). Day 5: Phone call + voicemail (references the emails). Day 7: LinkedIn connection request or message (references the email thread if connected). Day 10: Email with insight or resource. Day 14: Phone call. Day 18: Final email (breakup). The phone steps are often the most neglected — reps skip them because they're uncomfortable, which is exactly why the reps who don't skip them outperform.

Common multichannel outreach mistakes

1. Same message across all channels. Sending the same email message through LinkedIn DM and then calling to repeat the same pitch isn't multichannel — it's the same message on multiple networks. Each channel should use the appropriate format and tone: email is more formal and structured; LinkedIn DM is shorter and more conversational; phone requires natural spoken language.

2. Treating channels as independent rather than coordinated. 'I sent you an email a few days ago about [topic]' on the phone call creates continuity. Arriving on LinkedIn with no reference to the email thread misses the cumulative context effect.

3. Skipping phone. The channel most reps avoid is consistently the channel with the highest conversion per touch. Add one phone step per week minimum.

4. No timing logic. Sending email, LinkedIn, and calling on the same day creates a burst of contacts that looks aggressive and can generate complaints. Spread channel contacts across 2–3 day intervals.

How Gangly coordinates multichannel outreach

Gangly's Workflow Sequencer stages multi-channel sequences — email steps generated by Outreach Writer, phone steps surfaced as call tasks with Call Prep Engine context loaded, LinkedIn steps queued with a suggested message. All from a single dashboard. The rep's daily queue shows: three emails to approve, two calls to make, one LinkedIn to send — in priority order by signal strength and sequence position.
