LinkedIn outreach B2B: method and results 2026

LinkedIn has become the most powerful B2B outbound channel of 2026 · if you use it correctly. With over 900 million members and directly accessible decision-makers, it's an opportunity that few companies really exploit.

Why LinkedIn outreach converts better

A LinkedIn message arrives in the decision-maker's personal inbox, not in a spam folder. The sender's profile is visible · it creates trust immediately. And unlike cold email, a LinkedIn connection remains in the network after the campaign. The open rate of a well-targeted InMail often exceeds 40%.

The devlo method for LinkedIn outreach

Our 4-step approach: (1) Optimisation of the sender profile · professional photo, catchy headline, customer-value-oriented summary. (2) Precise targeting via Sales Navigator · title, sector, company size, location, seniority. (3) Sequence of 3-4 messages over 10-14 days · connection + value message + follow-up + breakup. (4) Customisation at scale · clay.com to enrich each profile with contextual data.

Typical results

On our LinkedIn 2026 campaigns: 25-40% acceptance rate for connection requests, depending on the sector, 8-15% response rate to messages, 2-5% appointment rate. Case in point: 52 qualified leads for Square Co in the biofuels sector, obtained mainly via LinkedIn.

Mistakes to avoid

Send a sales pitch as soon as the connection has been accepted ("bait and switch"). Use generic messages without personalisation. Not tracking KPIs (connection rate, response rate, appointment rate). Use a single sender for large volumes · diversify.

Conclusion

LinkedIn outreach is one of the B2B channels with the best ROI in 2026, but it requires a solid infrastructure, copywriting expertise and rigorous execution. That's exactly what we do at devlo for our customers in Switzerland, Belgium, France and DACH.
