How Agencies Can Build a More Predictable Email Pipeline, According to Matt Barker

In a recent LinkedIn post, Matt Barker discusses how agency founders can keep email sign-ups coming in when they are too busy to post. Barker frames the issue through his own results: a LinkedIn post brought in 15 sign-ups on Thursday, while Sunday brought just one. His post argues that founders should measure how quickly engagement fades and build a more dependable route to their email list.

“If you’re an agency founder who’s heads down all week, that drop from 15 to 1 is what an engine that only runs when you do looks like:”

Track the decline, not just the peak

According to Barker, looking only at the total response to a post can obscure how quickly its effect wears off. He shared a four-day sequence of sign-ups—15 on Thursday, 13 on Friday, seven on Saturday and one on Sunday—and noted that his last post that week went out Friday. The pattern, in his view, makes the gap between a strong launch and ongoing demand visible.

Barker recommends tracking sign-ups over a week so founders can see what happens after posting stops. That measure can help distinguish a sustained pipeline from one that depends on a steady stream of new content.

Compare social reach with email performance

Barker also urges readers to compare the movement of their LinkedIn reach with the steadier activity on their email list. For the same week, he reported post reach ranging from 2,928 to 37,335, while email opens ranged from 3,690 to 3,988. The figures illustrate his argument that social distribution can vary much more sharply than an owned audience’s engagement.

“Predictability and consistency is KEY.”

In Barker’s view, the comparison is useful because it shows where founders may be relying on a channel whose performance fluctuates. His post presents email as a more consistent foundation, while acknowledging that LinkedIn can still generate larger spikes in attention.

Turn existing expertise into an automated sequence

Rather than treating every sign-up as dependent on the next post, Barker suggests turning material from past calls and posts into a short email course. His own example is a seven-day sequence, with one email sent each day, including weekends. He says a Sunday subscriber entered the course automatically, without requiring him to publish something that day.

A repeatable starting point

Barker outlines four steps: choose an outcome buyers want, gather relevant teaching, shape it into a short course and automate delivery. This approach, as he describes it, gives new subscribers a consistent next step even when the founder is occupied with client work.

Keep a route to sign-up open

Barker’s final recommendation is to maintain a permanent sign-up link beyond individual posts. He says removing the link for a week produced a baseline of 11 sign-ups; after he restored it, more than 70 came in during the following week. Those results are his own, but they support the broader point he makes: a lasting route to the list can capture interest after a post’s reach fades.

His central advice to agency founders is to keep posting for bursts of reach while building a baseline that continues during busy weeks. The article reports and analyzes Barker’s LinkedIn post; its examples and recommendations are his.
