A multinational group with over 1 million contacts needed to manage mass mailings
without compromising its reputation.
What we did:
- Creation of separate subdomains and senders for different types of messages
- Advanced DNS setup with SPF, DKIM, and DMARC for each sender
- Internal team training and ongoing support for 3 months
Results:
- No blocks from major providers (Gmail, Outlook, Libero, etc.)
- IP reputation constantly monitored and under control
- Deliverability above 98% on all campaigns
