Email Hosting
Reliable, private business email that lands in the inbox
We run Mailcow on Unraid (Ryzen 9000‑class CPUs, hundreds of GB RAM, ~100 TB storage). We manage SPF, DKIM, DMARC, and spam filtering for excellent deliverability, and we reliably send tens of thousands of transactional and marketing emails.
Deliverability first
Serious hardware
Scale with confidence
We can help your business
We set up custom domains, user mailboxes, aliases, and secure access (IMAP/SMTP/ActiveSync). We migrate from Gmail/O365, configure SPF/DKIM/DMARC, and monitor deliverability so your emails land. Admin dashboards, backups, and retention policies included.
