Case study: an email campaign to 33,100 contacts
How a custom email tool helped prepare, test and run a campaign to 33,100 contacts over 18 days, with precise acceptance and rejection tracking.

When no plugin fits, we build the tool.
Client portals, bookings, online quotations, internal tools and connections to your software: some ways of working do not fit off-the-shelf software. We then develop a custom business application focused on what you need, and run it with you.
The signs
A custom tool becomes useful if…
- 01
Your quotations start in a copied spreadsheet and every version ends up with an error.
- 02
The same information is entered two or three times: into the website, management software and an Excel file.
- 03
Clients email you to check progress on their case because there is nowhere they can view it.
- 04
You have tried several plugins or subscriptions and none really fits the way you work.
What we develop
Web tools built for your business.
We start with your actual process, not a feature catalogue. Depending on the need, the tool lives within your WordPress website or alongside it as a standalone web application.
Client portal
A personal login where clients find documents, check progress on a case or upload files, without long email exchanges.
Bookings and registrations
Appointments, training or session registrations and requests for places: a process adapted to your rules, available slots and constraints.
Online quotations
A form that asks the right questions, calculates using your own rules and sends you a complete enquiry, ready to quote or approve.
Internal tool
Case tracking, a catalogue to maintain, a dashboard or contact database: a simple tool for the team that replaces files passed around.
Connections to your software
When your tools provide an API, we connect them: CRM, invoicing software, email platform, calendar or shared spreadsheet.
Automation
Repetitive tasks run automatically: follow-ups, exports, notifications and list preparation. A log shows what ran and what failed.
Making the right choice
Off-the-shelf software, a plugin or custom development?
A custom business application does not need to be a large software system. Often it is a well-designed quotation form, a place for clients to check progress or a small internal tool replacing three Excel files. What matters is that it fits the way you work, rather than forcing you to work around its limitations.
When off-the-shelf software is enough
For straightforward appointments, regular newsletters or standard invoicing, existing tools work very well. They are ready immediately and maintained by their publisher. In that case, our role is to help you choose, configure and connect the tool to your website.
When a plugin or adaptation is enough
If your website runs on WordPress, some needs can often be met within it: a filterable catalogue, registrations or separate routes for different audiences. That is what we did for CTCCE, whose website separates consultations and training through custom development.
When custom development is the right answer
Time spent exporting, correcting and reimporting data between tools can justify custom development, especially when these steps create errors. For a client contacting a database of 33,100 addresses, we developed a dedicated email tool: list import and deduplication, language-based message selection, sending spread across 18 days, acceptance and rejection logs, and the ability to pause and resume. The tool was then reused for a second organisation. Everything is detailed in the case study.
An internal tool focused on useful features
An internal tool does not need to reproduce every feature of a large platform. It covers the useful process, keeps a record of its actions and can be taken over by someone else when needed. That is what separates useful web application development from a project that keeps expanding.
How we work
A first version with a defined scope.
- 01
Understand the process
Together, we describe what happens today, step by step: who enters what, where, and where things get stuck. We also record what your current software already does.
- 02
Define the first version
We keep essential features and set aside those that would simply be convenient. The scope is written down before work starts.
- 03
Develop and test on your own cases
The tool is tested on real situations using a small portion of your data before being rolled out to the whole team.
- 04
Launch and support
Deployment on hosting in France, onboarding with the people using it, then fixes and improvements as it is used.
In practice

Read the case studyFrequently asked questions
What people often ask us.
Do we always need a custom tool?
No. If off-the-shelf software or a plugin meets your needs properly, it is often the best choice, and we will tell you. Custom development makes sense when workarounds take more time and cause more errors than the tool itself.
Can my application integrate with my WordPress website?
Yes, where appropriate: quotation forms, client portals and registrations can live within your existing website. A larger tool or one mainly used internally is developed separately and connected to the website.
Can you connect the tool to our existing software?
This is possible when your software provides an API or a reliable export method. We check this at the start, before promising a connection that might depend on a closed system.
Who looks after the tool once it is live?
We do. We host it in France, maintain it and develop it as needed. You keep a direct point of contact: the person who wrote the code.
How is the quotation prepared?
After an initial conversation about your process, we define a first version and quote for that precise scope. Later improvements are quoted separately once the tool is in use.
