Email Security & Deliverability That Actually Works

Your emails are under cyber attack. Your legitimate messages are being blocked from reaching recipient inboxes. We fix both.



We’re email experts. At SH Consulting, we don't just patch email problems - we build security-first infrastructure that protects your business from abuse while ensuring your legitimate emails reach the inbox every time.

The Email Crisis No One Talks About
35%
of companies are being spoofed - without even knowing it
30%
is considered a "good" open rate across most industries
1.5%
is the average spam complaint rate for newsletter and similar email campaigns

The problem: Email deliverability and security aren't separate issues. As providers like Google and Microsoft tighten defenses against bad actors, poorly configured legitimate senders get caught in the crossfire.

Our solution: Security-first email infrastructure that stops abuse AND ensures email delivery. You don't use ours, we improve & re-build yours. This is important because it gives you flexibility to choose among email partners and avoid vendor lock-in.
