Why AstroMail

Everything a real inbox
needs, nothing it doesn't

No per-seat surprises — just reliable inboxes, backed by a team that answers.

24/7 Global Support

Running into trouble with a mailbox or DNS record? Our technical experts are available around the clock to fix it fast.

Dedicated Business Email Infrastructure

SPF, DKIM, and DMARC set up on every domain. Blocklists are monitored 24/7 with delisting handled for you. Hosted MTA-STS enforces TLS with just two DNS records.

Renewal Price Stays the Same

No bait-and-switch pricing. Whatever you sign up for is exactly what you renew at — every single time.

Your domain, your data

Everything runs under your own domain. Export your mail or move on whenever you like — no lock-in, no hostage data.

Two-factor security

Lock every mailbox behind TOTP two-factor authentication, then issue app passwords for your standard mail clients.

GDPR Compliant Cloud Storage

Files and mailboxes alike are hosted on GDPR-compliant infrastructure, so your team's data stays compliant by default.

The Suite

Every mailbox comes with
a full productivity suite

No add-ons, no upsells — these tools are included on every AstroMail plan, from Starter to Business.

Sync Everywhere

Your mail, contacts, and calendar stay in sync across every device and desktop client.

ActiveSync
CalDAV/CardDAV
Exchange Web Services
POP3 · IMAP · SMTP

Cloud File Storage

Store and share files alongside every mailbox, no separate app required.

Built-in Productivity Suite

Edit documents, schedule meetings, and manage tasks without leaving your inbox.

Fetch Mail Support

Pull mail in from other accounts so you never have to check two inboxes again.

Security isn't a paid add-on with AstroMail

Every mailbox — regardless of storage tier — ships with the exact same protection, locked down by default from day one.

MXFilter AntiSpam & Virus Protection

Every message is filtered and scanned before it reaches your inbox, blocking spam and malware automatically.

Two-Factor Authentication

Add a second login step to every mailbox so a leaked password alone can't get anyone in.

SSL/TLS Encryption & DKIM/SPF/DMARC

Every connection is encrypted in transit, and full email authentication stops spoofed mail from ever using your domain.

Offsite Backups

Every mailbox is backed up off-site automatically, so a server issue never means a lost inbox.

Protection

Clean inbox, complete records

Peace of mind for IT and legal, included on every plan.

Message Archiving

Compliance & Retention

Every message in and out of your domain is captured at the spool level: a clean, unaltered copy for HIPAA, FINRA, or your own retention policy.

  • Spool-level capture
  • HIPAA / FINRA ready
  • Keyword & date search
  • EML export & restore

What is AstroMail?

AstroMail is AstronautCloud's business email hosting service, priced per mailbox. Every plan gives you a professional inbox at your own domain (you@yourcompany.com), full sync across devices, a built-in productivity suite, and enterprise-grade security.

You choose a storage tier — Starter (10 GB), Growth (20 GB), Team (50 GB), or Business (100 GB) — and pay that price per mailbox, per month, billed annually or every 3 years. Add or remove mailboxes as your team changes.

Yes. During setup you verify your existing domain and point your MX records to AstroMail, so you can start receiving mail at your own address right away.

No. AstroMail's renewal price is the same as your original price — there's no discounted first term followed by a hidden price hike.

Easy Mailbox Migration is included on every plan. Our team securely copies your existing emails, contacts, and calendar data into AstroMail with zero downtime and zero data loss.

Every mailbox includes MXFilter AntiSpam, virus scanning, two-factor authentication, SSL/TLS encryption, full DKIM/SPF/DMARC authentication, and automatic offsite backups — on every plan, at no extra cost.
