Help and Resources
Contract & accounting
As a mailbox business customer, you get a lot of flexibility:
- Flexible contracts
Add or remove email addresses at any time. Change account price plans with immediate effect. Adjust the storage space you have booked at short notice and only pay for what you need. - VAT invoices
You will receive a monthly VAT bulk invoice. Payment by bank transfer or Direct Debit can be arranged. - Short notice period
No annual contracts: Our customers tend to be with us because they want to be with us. At mailbox, notice periods are short as a matter of principle.
Support & Service
Depending on your chosen service package, our support specialists are available to be contacted by your account administrator by email ticket system or on the phone - even 24/7 in case of emergency. You decide which level of support you require.
- 2nd/3rd -Level Support
mailbox provides 2nd/3rd level support for you as a customer or your account administrator. - 1st level support as per mailbox price plan
We will be happy to provide you with 1st level support for your employees on request. Please note that this option is only available for our STANDARD and PREMIUM mailbox price plans. - Personal contact person

What is possible, what makes sense, what is feasible? As a business customer, you will be assigned a personal contact person in advance. They will contact you to discuss any issues and take care of coordinating your move. - Relocation with Audriga

This is a bit like a luxury relocation service: When you enter your new mailbox office, your desk and all files will be there waiting for you. - Need help with the setup?

Central administration & API
Everything under control. As a Business Mail customer, you get access to your own administration interface to configure or change your mail hosting settings at any time.

Manage your contract, domains, mailboxes, forwarding rules, passwords, storage space and all other account settings in a single place. - Enable individual settings
Specify if you want your users to be able to change their individual settings for spam filter, blacklist and backup. - Groupware in user groups
Define different user groups within your account. This makes it easier to share groupware resources such as calendars, contacts and files. - API for professionals
Do you maintain a larger IT environment and have your own administration processes? Or would you like to make our services available to your users as a reseller on your own website? All settings can be easily integrated into your infrastructure and modified through our API.
Server location in Germany
As a business customer, you benefit from the fact that our servers are physically located in Germany. We operate our services exclusively in redundant data centres in Berlin, and these meet the highest security standards. Your data is therefore subject to strict German data protection law and the GDPR - a decisive advantage when it comes to compliance requirements. We ensure maximum security through comprehensive physical and technical protection measures in our data centres. Most importantly, your data does not get transferred abroad, which avoids legal uncertainty.
