Most business email options are either expensive (Google Workspace at $6+/user) or unreliable. InterServer's private email hosting sits in between: $2.50/mo for professional business email with 25GB mailboxes, Outlook/webmail/mobile access, 100% uptime guarantee, and email archiving built in.
We ran this as a primary business email for four months, testing deliverability, Outlook connectivity, and the promised 100% uptime.
Quick Specs
Outlook, webmail, and mobile — all three work
We connected accounts via IMAP/SMTP in Outlook 2024, Microsoft 365, and Apple Mail. Configuration completed using InterServer's auto-detect settings in under 3 minutes per client. Mobile sync (iOS Mail and Android Gmail) worked identically. The webmail interface is clean and responsive — adequate for full-time use.
Deliverability to major providers (Gmail, Outlook.com, Yahoo) was 100% across 200 test emails during our testing period. No legitimate messages landed in spam.
25GB mailboxes + archiving means you never delete email again
At 25GB per mailbox, most users will never approach the storage limit. Combined with the built-in email archiving feature, this means you can configure archiving policies and retain years of email history without managing separate archive servers or paying for additional storage.
Unlimited aliases and forwarding are useful for business workflows: route orders@, support@, and billing@ to a single inbox, or set up team distribution lists without paying per address.
100% uptime guarantee — what it means in practice
InterServer backs their email hosting with a 100% uptime SLA. During our four-month test, we measured zero email downtime. SMTP delivery tests ran every 15 minutes from an external monitor — all 11,520 checks succeeded. For a business where email downtime means missed customer communications, this guarantee matters.
Pros & Cons
Is it right for you?
