The basics
What Is Business Email for Small Business?
Quick answer
Business email for small business explained in one minute
Business email is an email address on your own domain, such as you@yourcompany.com, instead of a free Gmail or Yahoo address. For a small business it is the simplest way to look professional and keep your mail under your control.
AstroMail is AstronautCloud's business email service, and it comes in two forms. With AstroMail per mailbox you choose a storage tier from 10 GB to 100 GB and pay for each mailbox. With AstroMail storage you pay for one shared pool of 10 to 100 GB and create unlimited mailboxes inside it.
Both include webmail, sync to your phone and desktop, a built-in productivity suite with video meetings and team chat, MXFilter antispam, two-factor authentication and free mailbox migration. The renewal price is the same as the sign-up price, and there is a 7-day money-back guarantee.

Why it matters
Why Small Businesses Use Business Email
A free address works until your business grows. A business email gives you the look, the control and the security from day one.
Security a small business can't build alone
MXFilter antispam, virus protection, two-factor authentication, SSL/TLS, DKIM, SPF and DMARC and offsite backups come with every mailbox at no extra cost.
Start small, add people as you hire
Begin with one mailbox, then add teammates as your business grows. Unlimited aliases and forwarders let one person receive mail for sales@, info@ and support@.
Spam protection
Keep Spam and Phishing Out of Your Small Business Inbox
Every minute you spend sorting junk is a minute not spent on customers. AstroMail business email filters spam for you, so likely junk goes to the Junk folder and real customer messages stay at the top of the inbox.
- Decide what happens to low, medium and high-probability spam
- Treat customers and partners in your contacts as trusted senders
- Block unwanted senders and whole domains in a few clicks
MXFilter antispam and virus protection come with every business email plan.
Never miss a customer
Reply to Customers Automatically, Even When You're Away
A quick reply keeps a new lead warm. The built-in autoresponder answers for you during holidays, busy days and after hours, so customers know their message arrived and when to expect your reply.
- Write one reply for colleagues and another for customers
- Each sender gets one reply a day, so nobody is flooded
- Switch it on and off with one toggle, with no extra app
Stay organised
Plan Your Week Around Business Hours With a Built-In Calendar
Keep meetings, deadlines and customer calls in the same place as your business email. Set your working hours, choose a default meeting length and reminder, and see tasks next to appointments, so you stay on schedule without paying for another app.
- Set business hours for each day of the week
- Default meeting length and reminders that fit how you work
- Tasks and appointments together in one calendar view
Account security
Protect Your Business Email With Two-Factor Authentication
Your inbox holds invoices, contracts and customer details. Two-factor authentication adds a second step at sign-in, so a stolen password alone is not enough to open a mailbox.
- Turn on two-factor authentication for each mailbox
- Add a recovery email address so you can always get back in
- Change your own password whenever you need to
SSL/TLS encryption, DKIM, SPF and DMARC are set up on every plan.

Fixed storage for every mailbox, from 10 GB to 100 GB. You pay per mailbox a month, so the cost per person is easy to predict and every person gets their own space.

AstroMail storage
One shared pool of 10 to 100 GB with unlimited mailboxes. You pay for the storage, not for each inbox, so adding a teammate costs nothing extra.

Business email is an email address on your own domain, such as you@yourcompany.com, instead of a free Gmail or Yahoo address. For a small business it means a professional address for you and your team, with spam filtering, security and backups handled by the host. AstroMail is AstronautCloud's business email service.
An address on your own domain looks professional, builds trust with customers and stays under your control. You can add or remove addresses as people join or leave, and the mail does not depend on one person's personal account.
Paying per mailbox, business email costs from $0.99 a month on a 3-year term, or $1.49 billed yearly. Five Starter mailboxes cost $4.95 a month on the 3-year term. Paying for storage instead, AstroMail 10 costs $1.81 a month on a 3-year term ($64.99 billed every 3 years) for unlimited mailboxes.
The lowest price per mailbox is Starter at $0.99 a month on a 3-year term, with 10 GB for each mailbox. The lowest price for all your mailboxes together is AstroMail 10 at $1.81 a month on a 3-year term, where every mailbox shares one 10 GB pool. Which is cheaper depends on how many people need a mailbox and how much mail they store.
Pay per mailbox when each person needs their own space, from 10 GB up to 100 GB, and you want a predictable cost per user. Pay for storage when you want unlimited mailboxes sharing one pool of 10 to 100 GB. On the 3-year term, a 10 GB pool costs less than Starter mailboxes from 2 mailboxes up, as long as all your mailboxes fit inside the pool.
With a storage plan you can create unlimited mailboxes, and they share the pool. With a per-mailbox plan you choose how many mailboxes you need and add or remove them as your team changes. Ask sales about volume discounts if you need 20 or more mailboxes.
