DEVLO.CH — SWISS B2B AGENCY
Swiss B2B Outbound Agency: Cold Email, LinkedIn and Calling
Coordinated cold email, LinkedIn and calling to create qualified meetings with the right decision-makers.
As a B2B outbound agency in Switzerland, devlo contacts your priority accounts through coordinated channels: personalized cold email, LinkedIn messages, targeted calls and synchronized follow-ups. We design and run the campaign end to end, from ICP definition to reply qualification and booked meetings in your sales calendar.
Unlike a single-channel approach, multichannel outbound reduces dependence on one inbox. We combine lemlist for email sequences, LinkedIn Sales Navigator for targeting and a phone script adapted to market objections. The expected output is not contact volume: it is commercial conversations with the right decision-makers at the right time.

By Charles Perret, Founder, devloWhy choose a multichannel outbound agency instead of one isolated channel?
Cold email reaches prospects who read and answer their inbox. LinkedIn outreach reaches people who interact more on the network. Calling creates conversations with busy decision-makers who rarely answer in writing. Combining these channels increases the number of ways a target account can engage.
The point is not raw volume but coordination. At devlo, each channel has a precise role in the sequence: email opens, LinkedIn builds credibility, calls accelerate. This orchestration reduces dependency on one channel and improves pipeline consistency.
In summary:
In short: multichannel serves qualification
- Cold email opens the conversation with a personalized and measurable angle.
- LinkedIn adds a presence signal and builds credibility with target decision-makers.
- Calling accelerates when the issue is urgent, complex or too strategic to stay only in writing.
- The sequence should be driven by ICP, timing and buying signals, not raw volume.
- devlo delivers the full orchestration: qualified accounts, messaging, follow-ups, reply qualification and CRM handoff.
| Criterion | Cold email only | devlo multichannel outbound |
|---|---|---|
| Decision-maker coverage | Depends heavily on email reading behavior | Email, LinkedIn and phone reinforce each other on the same account |
| Commercial signal | Written reply or no reply | Replies, connections, phone objections and qualified interest |
| Prioritization | Often based on a static list | Based on ICP, buying signals, seniority and reachability |
| Sales handoff | Replies need manual sorting | Meetings and context passed into the CRM or calendar |

FAQ multi-channel outbound
How long before the first appointments?
Generally 1 to 5 weeks, depending on the KPI and the channels activated.

What's the difference between multi-channel outbound and cold email alone?
Cold email reaches prospects who respond by email.
Cold email reaches prospects who respond by email. Multichannel adds LinkedIn and phone to reach decision-makers who prefer other channels, qualify objections faster and reduce dependence on one sequence.
Which signals trigger a multichannel sequence?
We prioritize accounts using ICP fit, target market, available buying signals, seniority level, decision-maker reachability and the likelihood that a meeting will be commercially useful.
