LinkedIn outbound started strong, then reply quality died. What would you diagnose?

Hi guys,

I’m trying to diagnose a LinkedIn outbound campaign that started strong and then died. First two weeks: 6 positive replies out of about 60 cold LinkedIn messages. All were new cold contacts: no warm intros, no previous engagement, no paid ads, no automation at scale. After that, performance fell off hard. Same target market, same type of profiles, same offer, same basic message, same account. For the last two months I’ve had hardly any replies and the scarce are polite “thanks, not interested” type of reply.

Because i noticed the drop I changed the volume after the initial period: volume dropped from around 15 sends/day to around 5 sends/day. So the sample size is not huge, but the reply quality changed too.
The message structure that worked initialy and stayed stayed the same basically:

1. Start with a company-specific regulatory or political issue
2. Connect it to P&L, growth, permits, project risk, investors or board/finance
3. Explain that we quantify those scenarios into financial impact
4. CTA: 15-minute demo + quick calculation on one current company dossier

The pitch in simple terms:
"In companies dealing with external/regulatory/business issues, teams often discuss the expected effort required, but less often the expected value at stake.
We translate those issues into financial impact, assumptions and decision options, so leadership can decide where intervention is worth it.
CTA was to show this in a 15-minute demo using their company as the example.

One possible related signal: a few months earlier I saw a similar pattern on LinkedIn content from the same account. At around 1,000 connections, some posts initially got decent reach, then reach suddenly slowed down hard. In one case I remember seeing only around 30 impressions after 8 hours. I’m not sure if that is related, but mentioning it in case account trust / visibility matters.


For people who have run LinkedIn outbound: what would you test first?

I'd test audience fatigue and message freshness first. The initial 6/60 suggests the offer resonated, but after that LinkedIn may have exhausted the most responsive prospects. Try rewriting the first line completely, changing the CTA from a demo to a low-friction question, and manually engaging with prospects before outreach. Also check whether your acceptance rate and profile views dropped around the same time—those can be early signals of reduced account visibility.

Thank you for responding!!
Do you think changing the offer from the 15 min demo to offering a free analysis of their company is enough of a change?
And after they've said yes and I'll send the analysis and then ask for a meeting? Is this how it works? Or no?

acc most likely got flagged by LinkedIn which would explain both the content reach dying around 1000 connections and the outreach replies dropping together.
