Charting growth synergy across multiple channels

When lemlist hit 2,000 users, our CEO noticed social media posts spiked signup conversions—yet our email list barely moved. Instead of choosing one channel, we tested repurposing a single guide. We broke a 2,000-word blog into a LinkedIn carousel, an email tutorial, and Quora answers over two weeks. Traffic from LinkedIn alone doubled our cold-email open rates.

By mapping how each touchpoint funneled into the next—LinkedIn buzz led to forum threads, which fed an email sequence—we discovered a multiplier effect. Each channel’s content worked as both standalone value and a teaser for another channel. This synergy created a feedback loop: blog readers joined the community, community posts drove site visits, and email nurtures reactivated cold leads.

In systems theory, this is called a “network effect”: the value of each node grows as it interacts. We soon formalized a 30-day repurpose cycle—every new asset triggered three cross-channel waves. Month after month, that loop accounted for 40% of our organic signups. Instead of mastering one channel, we embraced interconnected momentum.

First map out your main channels and their current yields, then pick one top-performing asset and transform it into three other formats—social post, forum answer, email snippet—spread over two weeks. Track the signing lifts between channels, then double down where you see the biggest cross-channel boost. Before you know it, you’ll have built a self-reinforcing growth engine.
