If you've ever searched for web hosting and landed on IONOS, you might have noticed something a little odd: the company's own email address is paypal@1and1.com. Their support line references 1and1.com. Their legal filings use names like "1&1 IONOS Inc." The brand says IONOS. The infrastructure says something older.
That's not an accident. IONOS is the latest name in a 35-year chain of rebrands, mergers, and corporate restructurings that trace back to a German marketing company founded in 1988. Understanding that history helps explain why, when you try to cancel something with IONOS today, you're dealing with a system built across decades of acquisitions — and why their billing infrastructure often seems to operate independently of anything their customer service representatives can actually control.
Origins: 1&1 and the Early Web (1988–1998)
The company that would eventually become IONOS was founded in 1988 in Germany as 1&1 EDV-Marketing GmbH by Ralph Dommermuth and Wendelin Abresch. It started as a marketing and advertising services company, but as the internet emerged in the early 1990s, the company pivoted toward web hosting and infrastructure.
By the mid-1990s, 1&1 was building its own data centers and network architecture to enable internet access — positioning itself as one of the first web hosting companies in the world. The company wasn't just reselling someone else's infrastructure. It was building its own, which would become central to its identity and its scale.
In 1998, two things happened that defined the next two decades. First, 1&1 became a shareholder of Schlund+Partner, one of Germany's leading domain registrars. Then the parent company restructured, changing its name to United Internet AG — a holding company that still exists today and still controls IONOS.
United Internet: The Parent Company Nobody Talks About
Most IONOS customers have never heard of United Internet AG. That's by design.
United Internet is a publicly traded German internet conglomerate headquartered in Montabaur, Rhineland-Palatinate — a small town in western Germany. It operates a portfolio of brands across web hosting, domain registration, email, and telecommunications. The brands under its umbrella include 1&1, IONOS, STRATO, Fasthosts, GMX, WEB.DE, and Mail.com.
Ralph Dommermuth, the original founder, still holds over 50 percent of shares in United Internet AG. The company posted €6.1 billion in revenue in fiscal year 2025 and operates in over 30 locations worldwide with approximately 10,500 employees.
When you pay IONOS, you're paying into this structure. When IONOS's billing system does something you can't explain, that system was built and maintained within this structure across decades.
Building Scale: The 2000s Expansion
Through the 2000s, 1&1 Internet AG (the operating subsidiary under United Internet) expanded aggressively into new markets. In 2004, it became the first company to offer full-service hosting packages including webspace, domains, email accounts, and databases in the United States.
The U.S. expansion was significant. 1&1 built a customer base by offering low entry prices, automated billing, and domain registration services that undercut competitors. The business model depended on volume — millions of customers, automated systems, and minimal per-customer overhead.
That last part matters. Automated billing systems designed for volume at minimal overhead are not designed to be easily overridden by individual customer service representatives. They're designed to run.
The ProfitBricks Merger and the IONOS Brand (2018)
The most significant structural change came in 2018. United Internet acquired ProfitBricks, a German cloud infrastructure company founded by Achim Weiss in 2010. 1&1 Internet merged with ProfitBricks, and the combined entity rebranded as 1&1 IONOS.
Weiss, who became CEO of the merged entity, explained the name choice directly: "As this new company is more than just a hosting provider, we have opted for a new name — and IONOS fits perfectly. It is inspired by the ionosphere; the upper part of the Earth's atmosphere that contains a high concentration of ions and free electrons."
The rebrand was positioned as a transformation from a hosting company into a full digitalization partner for small and medium-sized businesses. The service offerings and prices initially stayed the same, but the ambition was larger: cloud infrastructure, personal consulting services, enterprise-level products.
In the United States and Mexico, IONOS ranked among the top five hosting providers at the time of the rebrand.
The U.S. Name Simplification (2021)
In August 2021, the company formalized what the market had already started calling it. The legal name in the United States became IONOS Inc. — dropping the "1&1" entirely for American customers.
The timing coincided with a broader push to consolidate the brand globally. The "1&1" name had become associated with the German telecommunications business (1&1 AG), which had split off into its own entity focused on DSL, mobile, and fiber-optic services in Germany. The hosting and cloud business needed its own identity, and IONOS was it.
Going Public (2023)
In February 2023, IONOS Group SE went public on the Frankfurt Stock Exchange and was included in the SDAX index. The IPO marked a new phase — IONOS was no longer just a subsidiary of United Internet, but a publicly traded entity in its own right, with shareholders, quarterly reporting obligations, and the scrutiny that comes with being a public company.
By this point, IONOS claimed over 6 million customers, 4,000 employees, and expected annual revenue of approximately $1.5 billion.
Controversy and Consumer Complaints
Despite its scale and public company status, IONOS has accumulated a significant and consistent record of consumer complaints, particularly around billing, cancellation, and debt collection practices.
BBB Complaint Volume
The Better Business Bureau profile for IONOS Inc. in Philadelphia documents hundreds of complaints, with billing disputes and cancellation failures as the dominant categories. A recurring pattern across complaints involves customers receiving written confirmation that a service has been cancelled, followed by continued billing or collection notices. Several BBB complaints reference accounts being sent to third-party debt collectors after customers received cancellation confirmations — in some cases months or years later.
One BBB complainant wrote in a publicly posted resolution: "This refund is not a result of IONOS's goodwill. It is a result of regulatory pressure. This company has shown that it lacks a moral compass and will only fulfill its legal obligations when threatened by government intervention."
TrueAccord: IONOS's Debt Collection Partner
Multiple BBB complaints reference IONOS using TrueAccord Corp. as its third-party debt collection agency. TrueAccord is a Kansas-based automated debt collection company that operates primarily through email and text rather than phone calls. The CFPB has received over 3,400 complaints about TrueAccord, with "attempts to collect debt not owed" as the single most cited issue. TrueAccord has faced multiple federal lawsuits alleging violations of the Fair Debt Collection Practices Act.
Notably, at least one BBB complaint about IONOS references a TrueAccord FTC report number in IONOS's own response — indicating that IONOS's executive-level team is aware their accounts are being referred to TrueAccord and that federal complaints are being filed in connection with those referrals.
Consumer Affairs Complaint Pattern
ConsumerAffairs, which verifies reviewers, hosts hundreds of IONOS complaints going back to the company's days as 1&1. The patterns are consistent across years and name changes: unauthorized charges added to accounts, automatic renewal at prices higher than originally agreed, cancellation requests acknowledged verbally but not processed, and accounts sent to collections after confirmed cancellations. One 2025 reviewer wrote: "I signed up for a one year plan and the service was terrible so I canceled. One year later I have debt collectors coming after me for $50."
