about

Kolecto's aim is to simplify the day-to-day administrative and financial tasks of VSE & SME managers, with a simple, modular, connected solution that complies with the new e-billing regulations. In concrete terms, Kolecto speeds up the processing and dematerialization of customer and supplier invoices through automatic collection, intelligent classification, and an integrated reconciliation and payment interface.

01.Summary

As Kolecto enters an acceleration phase, supported by its nationwide distribution via the 39 Crédit Agricole Regional Banks, the email infrastructure becomes a central lever for success. Since the launch at the beginning of 2025, mailing volumes have been growing steadily - so Kolecto's marketing department has taken the lead in laying a sound, sustainable technical foundation with the help of Badsender. This strategic window of opportunity means that best practices can be implemented today, in anticipation of the massive ramp-up currently underway and planned for 2025.

02.challenges

Kolecto, a young, fast-growing platform, is anticipating a sharp increase in the number of emails it sends out: commercial, transactional and newsletters. This growth requires a high value-added email infrastructure:

Ultra-reliable, intelligent transactional emails, guaranteeing a smooth, reassuring experience for our users (notifications, reminders, security, data exports...).
Targeted, contextualized and technically impeccable marketing campaigns focused on our customers' real-life uses, to boost adoption and stimulate product engagement.
A regular editorial newsletter, designed as a reference point for VSE/SME managers, to establish Kolecto as the leading brand for financial management in France.

03.Solutions

The mission was carried out in two stages: a complete audit of the email infrastructure, followed by operational support to implement the recommendations. The aim was to secure the increase in volume, reinforce deliverability and upgrade the skills of the teams.

Analyze deliverability and current configuration of Kolecto emails
Receive advice on how to solidify Kolecto's deliverability in advance of a major volume increase
Help teams to increase their skills (and knowledge) in deliverability issues.
Redefining deliverability architecture
The mission was carried out in two phases: an audit phase followed by a coaching phase to implement the recommendations.

04.Result

The existing structure proved to be sound:

No major deliverability problems detected
Good overall reputation of sending domains
Satisfactory engagement rates across all email types
Existing infrastructure functional and adapted to current needs.

The audit identified areas for optimization: better technical authentication (SPF, DKIM, DMARC), compartmentalization by email type (marketing, transactional, notifications), and more comprehensive monitoring.
