The problem
You're sending from a European mail server. US enterprise filters distrust foreign IPs and downrank your messages.
Our solution
We provision US-based sending infrastructure (warmed-up domains, SPF/DKIM/DMARC, dedicated IPs), and run your outbound from inside the US.
Sender reputation is geographic
Microsoft Defender weighs sender geography. EU IPs to US enterprise inboxes ramp slower.
Domain warmup is the slow but right way
We warm up 3-5 secondary domains over 4 weeks so your primary stays clean.
Reply rate, not open rate, is the real KPI
Apple Mail killed open rate. Track replies and meetings booked instead.
