About Jerome

🧑‍💼 About me
💡 20 years of IT experience, including 5 in cybersecurity, with a specialization in email security and email deliverability.

✉️ The problem you are facing
Are your emails no longer arriving? Do you think you are compliant with SPF, DKIM, DMARC?
Since 2024, Gmail and Yahoo have been rejecting improperly authenticated messages. Microsoft will follow suit in May 2025.

🎯 My role
To support you in your compliance, without disrupting your mailings.

🔍 How?
1 - Complete technical evaluation of your domain and your sending tools
2 - Progressive compliance with SPF, DKIM, and DMARC, up to "reject" mode if possible.
3 - Implementation of a compliant unsubscribe mechanism (list-unsubscribe), now mandatory.
4 - Monitoring of sending reputation (Google Postmaster Tools, Microsoft SNDS, DMARC reports)
5 - Support for your marketing and IT teams so they understand and master the stakes.
6 - Documentation, skills transfer, and reporting to ensure long-term autonomy.

🤝 Why me?
With over 2,000 domains secured under DMARC in reject mode, I am capable of managing this type of large-scale deployment, while maintaining an accessible approach tailored to each stakeholder.

I bring to agencies and their clients cutting-edge expertise, clear language, and a results-oriented approach: less spam, better deliverability, full compliance.

My strength: I speak technically with IT teams and concretely with marketing teams, so that everyone knows where they are going... and why it matters.
