Security isn't a paid add-on with AstroMail

Every mailbox on every pool ships with the exact same protection, locked down by default from day one.

Virus Protection

Every message is scanned before it reaches your inbox, blocking 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.

The Suite

One pool. Every mailbox
shares the full suite

Every mailbox on your domain gets the same tools — no add-ons, no per-seat upsells.

One Shared Storage Pool

Upload business files, videos, or anything else, then share the link with clients and teammates. Reachable over FTPS and SFTP for bulk transfers too.

How does storage-pool pricing work?

Instead of paying per mailbox, you pick a total storage pool — 10, 20, 30, or 100 GB — and split it across as many mailboxes as you like on your domain. Add a new teammate anytime at no extra charge; you only pay more when you need a bigger pool.

Correct — every AstroMail storage plan includes unlimited mailboxes. The only thing that's metered is the shared storage pool, so a team of 3 and a team of 30 can be on the exact same plan.

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.
