01 The Challenge

No systems, no process, no predictable pipeline

Verzendbazen.nl is a Dutch fulfillment company specializing in storage, pick & pack, and shipping services for e-commerce businesses. Their target market: fast-growing online stores in the Netherlands and Belgium that need reliable, scalable fulfillment.

Before working with Closedin, outreach was ad hoc with limited targeting and poor results. They lacked proper domain setups, warmup, and deliverability management. Without predictable sales conversations, their growth was capped, and they needed a way to systematically fill the pipeline without hiring an expensive in-house outbound team.

02 The Solution

A complete outbound engine from scratch

We built a full outbound system combining ICP identification, Clay worktable building, and technical infrastructure setup to generate qualified conversations at scale.

01
ICP Identification
Ran a deep dive session to define Verzendbazen's ideal client profile based on sector, company size, geography, and tech stack.
02
Clay Worktable Build
Using Clay, we scraped and enriched leads across 100+ sources, filtering by ICP attributes to build highly targeted lead lists.
03
Technical Infrastructure
Set up and monitored domains, inboxes, DKIM/SPF/DMARC, and warming systems to maximize deliverability throughout the campaigns.
04
Messaging, Sequencing & Campaign Management
Crafted personalized cold email sequences designed to resonate with e-commerce founders. Monitored replies, managed inboxes, and optimized campaigns continuously.

Closedin built us an outbound machine we could never have created internally. Within weeks we had conversations booked with exactly the type of e-commerce founders we wanted to reach. The campaigns performed so well that we had to expand our team just to keep up with demand.

03 The Results

From ad hoc outreach to a predictable growth engine

The campaign volume was so successful that Verzendbazen had to hire a new team member just to handle the incoming requests. Outbound went from an afterthought to their primary growth channel.
