Zoom on Isoskele
Isoskele is a data marketing agency recognized for its expertise in personalized communication and multichannel relationship campaigns. Its mission: to help brands create relevant and engaging customer experiences, based on data and automation.
The agency is structured around several expert areas: email, SMS, WhatsApp, affiliation, and data media, in order to offer a comprehensive approach, from targeting to distribution. Isoskele also designs custom advertising campaigns, combining creativity and performance. Its clients belong to various sectors: automotive, energy, food service, telecommunications, insurance… as many fields where data reliability is the key to success.
The challenge: a crucial need for email verification
Because it manages its sending servers itself, Isoskele places the reputation of these servers at the heart of its marketing strategy. A single degraded database containing invalid, inactive, or incorrectly entered addresses can suffice to compromise weeks of work. Poor data quality leads to bounces, blocks, and declining performance.
Consequences? The entire communication chain is weakened: messages reach fewer recipients, the sender’s reputation deteriorates, and conversion rates drop.
Aware of these challenges, the agency decided to equip itself with a reliable, fast, and GDPR-compliant email verification tool — a partner capable of ensuring a high level of quality without burdening internal processes.
Why Captain Verify?
During its search for a solution, two criteria immediately stood out:
- European compliance and GDPR respect, naturally leading to a 100% French provider;
- Clear and accessible pricing, allowing for regular file verification without impacting the marketing budget.
Captain Verify perfectly met these requirements, combining technical rigor, reliability, and ease of use.
The fact that it is a French company was really decisive for us. We wanted a local provider that shares our compliance and quality requirements.
specified the data media department manager.
Simple use and concrete results
Today, Isoskele primarily uses Captain Verify’s online platform to check the validity of its files before each campaign. The interface, intuitive and fluid, allows the team to act quickly without wasting time on technical setup.
We don’t get lost, and the results are immediate.
The verifications are carried out before sending, which significantly reduces bounce rates and improves overall deliverability. The teams now observe cleaner, more effective campaigns, and a sending domain better valued by ISPs and webmails.
The agency is also interested in integration via Captain Verify’s API, to automate the control process and further optimize its data flows. The only current constraint: the limit of allowed calls, considered a bit low for their volume, but a parameter the team hopes will evolve soon.
Results?
The benefits are clear and measurable: email deliverability has significantly improved, costs related to errors have decreased, and operational peace of mind has settled in.
Isoskele’s opinion on Captain Verify
What we appreciate with Captain Verify is its simplicity, precision, and efficiency. It’s a tool we recommend without hesitation to other agencies that want to maintain or improve their campaign performance.
For Isoskele, data quality is not just a technical detail: it’s a real lever for marketing performance. And with Captain Verify, this requirement becomes an operational reality, serving campaigns that are safer, more effective, and more profitable.
