Multi-channel outreach is the practice of running coordinated outbound touches across email, LinkedIn, phone, video, direct mail, and other channels against the same prospect. The mechanism: different humans respond on different channels, and seeing the same name three times across three channels feels different from seeing it three times in one inbox. Multi-channel sequences typically lift reply rates 2-3x over email-only sequences and lift meeting-booking rates by 30-50%.
Why does multi-channel work better than email-only?
Two reasons. First, channel preference: roughly 40% of B2B buyers prefer email, 30% prefer LinkedIn, 20% prefer phone, and the remaining 10% are mixed. An email-only motion misses 60% of prospects who would have engaged if you'd reached them where they live. Second, brand familiarity: seeing the same sender name across email and LinkedIn primes the prospect that you're real and intentional, not a spray-and-pray campaign. The combined effect (channel match plus familiarity) is what lifts reply rate.
A modern multi-channel cadence might look like: Day 1 email, Day 3 LinkedIn connection request, Day 5 LinkedIn message after connect, Day 7 phone call, Day 10 follow-up email, Day 14 LinkedIn voice note, Day 18 break-up email. Eight touches over 18 days across three channels.
How do you actually run multi-channel at scale?
Three practical problems to solve. First, channel coordination: when a prospect replies on LinkedIn, the email sequence must pause automatically. Without integration, you'll send a "just following up" email two days after they've already booked a call. Second, channel ownership: the same SDR should own all channels for the same prospect to keep voice and context consistent. Splitting email and phone between two reps confuses prospects and erodes the familiarity benefit. Third, channel quality: a sloppy LinkedIn message poisons the well for a good cold call later in the same cadence. ReachIQ's automated sequences coordinate email, LinkedIn, and phone with per-recipient send-time optimization and auto-pause on reply across all channels.

What's the right channel mix?
For most B2B mid-market motions: 50-60% email, 20-25% LinkedIn, 15-20% phone, and the remainder split between video and other channels. Enterprise motions skew more toward phone and LinkedIn; SMB motions skew more toward email volume.
Does LinkedIn-only outreach work?
Sometimes, especially for senior buyers who treat email as low-priority and LinkedIn as a working channel. But LinkedIn has hard volume limits (around 100 invites per week before the platform restricts you) and slower velocity. As a primary channel it caps your pipeline; as a complement to email and phone it lifts reply rates significantly.
Should I cold-call before or after sending email?
After, in most modern playbooks. Email plus LinkedIn first warms the prospect just enough that a cold call referencing those touches ("I emailed you earlier this week") has a higher pickup and conversion rate than a pure cold dial. The exception is very transactional, time-sensitive verticals where speed beats context.
