Overview
- .gmx is a brand gTLD created for the GMX mail brand and applied for under ICANN's New gTLD Program.
- The TLD's purpose is to expand the available namespace for GMX email addresses and provide memorable, brand-aligned second-level names.
History
- Applied for by 1&1 Mail & Media GmbH (part of United Internet / 1&1 Group) during ICANN's New gTLD Program.
- A Registry Agreement with ICANN was signed on 24 April 2014.
- .gmx was delegated to the DNS root zone on 5 September 2014.
- The registry is listed as Knipp Medien und Kommunikation GmbH (Knipp); the brand operator is 1&1 Mail & Media GmbH.
Usage and Audience
- Intended audience:
- GMX users and customers of 1&1 Mail & Media products and portals.
- Email account holders who need additional or more memorable addresses.
- Context and scale from the applicant's submission:
- GMX is an established email service (described as an email pioneer) with millions of users in German-speaking countries.
- Mail&Media (which operates WEB.DE, GMX and MAIL.COM) reported tens of millions of users across its brands and cited around 15,000 new registrations per day for email services, motivating the need for expanded namespace.
- Use case: the TLD is primarily used to create email addresses and brand-related second-level names under .gmx.
Registration Rules
- Second-level registrations:
- Mail&Media will always be the owner of all second-level registrations under .gmx.
- Labels must be 1 to 63 characters long.
- Allowed characters are ASCII letters, digits and hyphens.
- Hyphens are not permitted in the third and fourth positions of a label.
- Contact and WHOIS requirements:
- Contact information is collected in compliance with Specification 4 of the New gTLD Agreement.
- Registrant contact details to be provided include name, organization name, address, phone, fax and email contact details.
SEO and Brand Impact
- As a brand gTLD, .gmx is positioned to reinforce GMX’s brand identity and extend its controlled namespace for email and related services.
- Centralized ownership by Mail&Media means the brand retains control over available second-level names, supporting consistent branding and trust for GMX-issued addresses.
- The stated mission for .gmx is to offer "prestigious and easy-to-remember" email addresses to GMX's growing customer base, addressing scarcity of desirable addresses under legacy domains.
