Emails blacklisted. Clients hadn't been receiving invoices for months.
The challenge
An accounting firm with 12 users between Venice and Mestre discovered — almost by accident — that emails sent to clients were ending up in spam or being silently dropped. Electronic invoices sent by email weren't arriving, reminders weren't being read, professional communication was compromised. The cause: the domain was blacklisted due to missing SPF, DKIM and DMARC, and Microsoft 365 was configured without any email security measures. No MFA, no anti-phishing protection, no visibility into sent email status.
The solution
We performed a complete email configuration: correct SPF, DKIM and DMARC on the domain, delisting requests from all active blacklists, domain reputation monitoring. Migration to Microsoft 365 Business Premium with Exchange Online Protection and Defender for Office 365 active: advanced anti-phishing, anti-spoofing, real-time link and attachment protection. Mandatory MFA on all 12 user accounts with assisted rollout and training. Implementation of GDPR-aligned security policies: conditional access, data loss prevention on fiscal documents, audit logs activated. Teams and SharePoint for internal collaboration and secure document sharing with clients.
The results
Zero emails in spam or blocked in the 12 months after configuration
Domain removed from all blacklists within 48 hours
MFA active on 100% of accounts: no unauthorized access
Productivity increased with Teams: centralized meetings and documents
Strengthened GDPR: audit log, DLP and conditional access documented
“We didn't even know our emails were ending up in our clients' spam.”
