Built on Mailcow and hardened for production. We run the infrastructure — you own the data.
TLS enforced on all connections. Data at rest encrypted. No unencrypted SMTP relay, ever.
Full mailbox snapshots every 24 hours with 30-day retention. Point-in-time recovery available on request.
No 15GB Google cap nonsense. Accounts are provisioned with generous storage scaled to your actual needs.
Bring any domain. We configure MX, SPF, DKIM, and DMARC for you. Multiple domains per account supported.
Standard IMAP/SMTP — works with Outlook, Apple Mail, iOS Mail, Thunderbird, and any compliant client.
Rspamd-powered filtering with greylisting, DNSBL checks, and per-domain policy controls.
Full-featured SOGo webmail with calendar and contacts sync. No app install required.
Your email does not share a server with thousands of other senders. Dedicated IP, clean reputation.
Bounce tracking, DMARC aggregate reports, and delivery logs so you always know what's happening.
When you use free email, you are the inventory. 365Sender runs on infrastructure you control, with no ad targeting, no data mining, and no third-party access — ever.
Every organization has different needs. We quote based on number of domains, mailboxes, storage, and support level — not a one-size-fits-all plan.
Tell us how many domains you need, how many mailboxes, and how much storage. We'll build a quote that fits — with no overages, no surprise fees, and no lock-in contracts.
Getting started takes less than 24 hours. Point your domain, we handle the rest.
