Many established companies still run email on a server in their own building. It made sense when they set it up. But as threats grow and IT teams stretch thinner, more organisations are asking whether hosted email is now the smarter choice. Here’s an honest comparison.
What each option means
On-premise email means you buy, install and maintain your own mail server hardware and software, usually in your office or a server room.
Hosted email means a specialist provider runs the servers in professional data centres, and you manage your users through an online admin panel.
Comparison at a glance
| Factor | On-premise | Hosted |
| Upfront cost | High: hardware, licences, setup | Low: subscription per mailbox |
| Ongoing maintenance | Your IT team: patches, upgrades, backups | Handled by the provider |
| Security updates | Depends on your team’s capacity | Applied continuously by specialists |
| Spam and virus protection | Must be bought and managed separately | Included, often AI-driven |
| Reliability | Vulnerable to local power, internet or hardware failures | Redundant data centre infrastructure |
| Scalability | Limited by hardware | Add mailboxes in minutes |
| Remote access | Requires careful configuration | Built in, including mobile apps |
| Control | Full physical control | Full admin control without hardware |
The hidden costs of on-premise
The server is only the beginning. On-premise email also needs:
- Backup systems and off-site copies.
- Antispam and antivirus licences.
- Power, cooling and physical security.
- Skilled staff time for monitoring and troubleshooting.
- Hardware replacement every few years.
When something breaks at midnight, someone has to fix it.
The security question
On-premise servers are only as secure as their last update. Many breaches exploit known vulnerabilities in mail servers that weren’t patched in time. Hosted providers employ specialists whose job is to keep servers updated, monitored and hardened, and they can roll out protections like AI antispam, two-factor authentication and country-based login restrictions to every mailbox at once.
When on-premise still makes sense
A small number of organisations have strict requirements for physical control of data or operate in isolated networks. For most businesses, however, the cost and risk of self-hosting outweigh the benefits.
Making the move
Migrating from an on-premise server to hosted email can be done in stages with minimal disruption: set up the new mailboxes, copy existing mail, switch DNS records and retire the old server once everything is confirmed.
