IONOS mail server with reliable protection

Digital security is never to be underestimated. Your emails may sometimes contain private information which, should not be accessible to third parties and should be kept safe. An email server from IONOS provides both these assurances. With the help of firewalls and filters, we’ll secure your emails against unwanted access and dangerous attacks. You can count on the high data protection standards. In addition, we perform automatic backups on a daily basis. This means that your data cannot be lost - even in the event of a natural disaster! IONOS’s data centers are certified according to ISO/IEC 27001:2013 and are geo-redundantly mirrored. Should one data center fail, another can step in immediately.

Advantages of mail hosting with the IONOS mail servers

01

Own mail domain – a professional impression

With all email offers from IONOS you will receive your own email domain free of charge. Instead of using the domain of a free email provider, you can make a professional impression with your own company name. It’ll give the impression that you’re serious and committed to your business. Even in the private sector, using your own domain looks impressive.
02

Generous storage space for multiple mailboxes

With up to 10 mailboxes and up to 50 GB, you or your employees have a lot of space at your disposal for messages and data. The email servers are also easily scalable and can grow with your business. Book additional mailboxes or more storage at any time to provide permanent space even for large files.
03

No advertising, no spam, highest virus protection

When hosting mail with IONOS email servers, we will help you keep your mailbox spam and virus free. Thanks to modern filters and firewalls, there’s nothing to worry about. You can forget about having to use ad-blockers, too, because with an email package from IONOS, you won’t be constantly disturbed at work by advertisements.
